9:00 - 12:00 PMTutorial Room 1
Tutorial 1

The tutorial will begin by surveying the properties and availability of sunlight, introducing the necessary measures and some commonly used data sources. A simple thermodynamic model for solar power conversion will be established to place an upper bound to the conversion efficiency. It will then be shown that using a semiconductor absorber leads to the usual measures for solar cell performance, short-circuit current, open circuit voltage and fill factor and introduces additional constraints to photovoltaic power conversion leading to the Shockley-Queisser efficiency limit. The carrier transport and recombination processes that are present in practical solar cells will be discussed in the context of Shockley’s diode equation and establishing analytical models for solar cell dark current, quantum efficiency and reciprocity between absorption and emission, or equivalently absorption and open circuit voltage. Having established a framework for understanding PV devices, several solar cell technologies will be surveyed (including crystalline silicon, CdTe, CIGS, organic and perovskite) considering both their present laboratory status and manufacturing processes. The application of these modules in PV power systems will be surveyed together with the economic and life-cycle metrics that are commonly used to determine the feasibility and desirability. The tutorial will conclude with a brief perspective on possible future scenarios for PV power generation and technological evolution

9:00 - 12:00 PMTutorial Room 2
Tutorial 2

This tutorial will discuss cell and module testing. A particular emphasis will be placed on best practice for testing Silicon devices under industrial conditions, at calibration laboratories, and in R&D. Strategies for minimizing uncertainties will be presented, based on the fundamentals of the equipment and also the device physics behind concepts such as the effects of cell capacitance, illumination non-uniformity, cell mismatch, and the module circuits including bypass diodes. The ambiguities in measuring the “efficiency” of cells with vanishingly little Ag in the busbars is an especially-challenging reality. The use of production IV testing to implement cell-by-cell advanced diagnostics and process control correlated with in-line measurements will be described.


Silicon Cell And Module Testing: Best Practice For Silicon R&D And Production

9:00 - 12:00 PMTutorial Room 3
Tutorial 3

This tutorial will begin with a brief introduction on what is needed to make a solar cell out of a semiconductor, thereby briefly explaining the basics of photovoltaics. We will then show different strategies to make a good solar cell, introducing surface passivation, light trapping, local contacts and local doping, always using typical Si solar cell structures as examples. From this we will go on looking into making really good Si solar cells by using passivating contacts and interdigitated back contact (IBC) schemes. This will then be topped by analyzing the potential of multi-junction cells on Si. In the second section of this tutorial, we will look a bit closer at Si solar cells currently in production and the latest trends in the industry, such as structural diversification, increasing number of busbars, making solar cells bifacial, using half cells and shingling. We will further give an overview of the importance of field performance and reliability, covering different degradation mechanisms and the importance of considering the complete lifecycle of silicon PV modules for sustainability.


Silicon Pv Technology: From Cradle To Grave
Anastasia Soeriyadi, Udo Romer

9:00 - 12:00 PMTutorial Room 4
Tutorial 4

This tutorial provides a high-level view of utility-scale PV system design, equipment selection, as well as a discussion of various plant optimization approaches that makes the plant viable. It also includes a discussion of several factors that have made significant PV growth possible. Next insights into practices that are necessary to meet current and future grid integration challenges will be discussed. Finally, the tutorial provides guidance on factors that make the combination of solar and storage more effective in addressing challenges arising from increased solar penetration.

9:00 - 12:00 PMTutorial Room 5
Tutorial 5

This tutorial will review the methodology and most recent results of solar and storage technoeconomic analysis at the National Renewable Energy Laboratory's (NREL) Strategic Energy Analysis Center (SEAC). From bottom-up component manufacturing costs to project levelized cost of energy (LCOE) and levelized cost of storage (LCOS), this tutorial will provide an opportunity to review the economics and cross-technology competitiveness of solar and storage systems.


Bottom-Up Manufacturing Costs Analysis Of The Pv Module Supply Chain And The Economics Of Pv Systems Coupled With Storage

1:00 - 4:00 PMTutorial Room 1
Tutorial 6

This tutorial will describe field experiences with PV modules and how identification of failure modes can lead to the development of accelerated stress tests that are used to develop more reliable and durable products. Proper application of these stress tests through qualification testing along with implementation of quality management systems in module manufacturing led to improvements in module lifetimes and extensions of the product warranties. The tutorial will review recent research being done to improve reliability and durability with an ultimate goal of try to develop a method of assessing module lifetimes


Reliability And Durability Of Photovoltaic Modules
John Wohlgemuth

1:00 - 4:00 PMTutorial Room 2
Tutorial 7

This tutorial will give a brief general introduction to the field of multijunction solar cells for the use in terrestrial and space systems, including basic theoretical considerations of the benefits of using several junctions to convert the broad solar spectrum into electricity. We will then separate the remainder into two main Si-based hybrid tandem solar cell technology areas: III-V (with some consideration of other inorganic materials) and perovskite. Within, we will review the fundamentals of the materials systems themselves, including techniques used for producing them at photovoltaic qualities and the various unique complexities associated with the fabrication processes. Key issues related to efficiency- and reliability-limiting defects and properties will be highlighted, including recent develops toward their mitigation. The various different device architectures that have thus far been investigated within these tandem photovoltaic systems will also be reviewed, with an eye toward future progress.

1:00 - 4:00 PMTutorial Room 3
Tutorial 8

The promise of thin film photovoltaic technologies has always been to reduce material and production costs while providing high conversion efficiency to achieve competitive cost. More recently their low energy payback time has been recognized as a critical advantage in carbon reduction strategies reliant on TW-scale electrification. CdTe and Cu(In,Ga)Se2 (CIGS) (as well as perovskites, subject of another tutorial) have in the past decade demonstrated conversion efficiencies in the same >20% range as multicrystalline Si. The fact that these technologies can achieve such high performance is truly remarkable because they consist of heterogeneous stacks of polycrystalline material layers with grain boundaries and interfaces spaced only microns from each other. What special attributes enable such high performance from such structurally imperfect materials? What are the process requirements for their cost-effective production? This tutorial will introduce participants to the leading thin film technologies ranging from the commercially successful to those in research or development stages. We will examine their materials, processing methods, device structures, and how these come together. The outstanding challenges will be discussed for each technology and materials and device concepts on the horizon will be introduced

1:00 - 4:00 PMTutorial Room 4
Tutorial 9

This tutorial will explore strategies, costs and timelines for deep renewable electrification of energy services leading to rapid reductions in global greenhouse emission of three quarters at low cost. Solar photovoltaics (PV) and wind constitute about two thirds of global annual net new generation capacity additions. Balancing an electricity system with 50-100% variable PV and wind is straightforward using off-the-shelf techniques comprising strong interconnection over large areas (million km2) to smooth out local weather; storage; demand management; and occasional spillage of renewable electricity. We will explore the technology and costs of HVDC long-distance transmission; storage in the form of pumped hydro and batteries; and the interplay of storage, transmission and spillage. Reference will be made to Australia which is installing PV and wind 4-5 times faster per capita than the EU, USA, Japan or China. Emissions reductions of 50% can be achieved through conversion of electricity supply to PV & wind, coupled with conversion of land transport to renewable electricity (mostly via electric vehicles) and low temperature air & water heating & cooling to renewable electricity (mostly via heat pumps). This requires only off-the-shelf technology but requires an increase in global electricity production of 50%. Longer-term opportunities for emissions reductions will be explored including conversion of industrial heating to renewable electricity; and the use of PV and wind to create energy-rich metals, materials and synthetic fuels to eliminate emissions from industrial processes and aviation.

100% Renewable Future

1:00 - 4:00 PMTutorial Room 5
Tutorial 10

The performance of photovoltaic devices is governed by the structural and chemical properties of the materials used as well as the interactions between the different materials that make up the devices. Understanding these properties requires the use of a variety of characterization techniques based on different probing methods designed to expose specific material properties. Electron beams are one type probe that allow researchers to probe the structure, chemistry, and electro-optical properties of photovoltaic materials from millimeter-scale down to the atomic-scale. In this tutorial we will provide a detailed survey of electron beam based characterization techniques used to study photovoltaic materials and devices from routine analyses through cutting edge methods. The discussion of each technique will focus on what information can be attained (as well as what cannot) and how that information can be related to photovoltaic parameters. One critical factor in the interpretation of electron beam based characterization data is understanding where the information corresponds to within the sample (e.g. surface, bulk, etc.…). Within a portion of this tutorial we will also provide an interactive session focused on modeling the interaction volume for scanning electron microscopy (SEM) and transmission electron microscopy (TEM) experiments using open access software available to all attendees. Following the technique discussion and interactive modeling session we will survey current material problems related to different photovoltaic materials (CdTe, CIGS, III-Vs, silicon, halide-perovskites) in the context of electron beam based characterization techniques.

Introduction: A hot carrier solar cell is a device that offers the potential to reduce thermalization losses in the material and could potentially double the efficiency of single junction solar cells (30% to > 60%), which would be a significant breakthrough for the photovoltaics community. Although these hot carrier devices have been the source of a considerable amount of research over the last 10 to 15 years, the realization of a practical solution to this challenging problem has thus far eluded researchers. In this topical discussion, several experts in the community will discuss the evolution of this field. Specifically, recent progress towards the realization of hot carrier solar cells in which several experimental works have demonstrated the potential of such systems. Despite this progress several significant challenges remain. It is expected this new progress and the outlook for this field in general, will stimulate considerable debate from both the panel and the wider live audience. Panelists: Gavin Conibeer, University of New South Wales; Stephen M. Goodnick, Arizona State University; Jean Francois Guillemoles, IPVF, France; Louise C. Hirst, University of Cambridge; Art Nozik, University of Colorado/NREL.

JOINT SESSION AREA 5/8 Advanced characterization of PV modules and systems, incl. performance testing and standards

Papers focusing on characterization of complete modules and systems where the nature of the device is dominated by the ensemble of microscopic behaviors distributed throughout a large area rather than the understanding of individual microscopic behaviors should be submitted in this Sub-Area. For example, papers in this Sub-area could focus on methods such as LBIC or electroluminescence specifically as applied to understanding module performance rather than the same methods applied to small areas of device. Other examples of papers relevant to this area include adaptation of existing methods to characterize modules from emerging technologies such as perovskites or addressing the characterization of degradation mechanisms of modules or systems of those materials.

Matching Problems and Models: Speed Dating for the Advancement of 3rd Generation Solar Cells

Forced to stay out of our labs, many of us have been thinking how to advance the development of 3rd generation solar cells by employing computational methods. There is a large array of widely available methods for analyzing and understanding advanced photovoltaics, but choosing the right tool and getting started using it can be challenging. We hope to match scientists who have computational needs with experts in the respective fields to either get started or to have a longer collaboration. This event will have experts in modeling device physics relevant to Area 1. We will begin with an overview of the capabilities of these various tools, and then experts will provide 5-minute overviews on the application of their modelling expertise. We will split into breakout rooms centered on the different methods with the goal of giving useful advice and establishing new collaborations. This session is moderated by Louise Hirst from the University of Cambridge. Panelists: Rebecca Saive, University of Twente; Diego Alonso-Álvarez, Imperial College; Matthew Lumb, NRL/George Washington University; Jacob Krich, University of Ottawa; Yongjie Zou, Arizona State University
