SC1 Short Course on Thin Film Deposition (offered on Saturday)

Instructor: Dr. Angus Rockett, Professor, Department of Materials Science and Engineering, University of Illinois Urbana-Champaign

This full day short course introduces students to the fundamentals of vapor phase deposition processes, thin film nucleation and growth, epitaxy, and the specific processes of evaporation, sputtering, and chemical vapor deposition (including a brief introduction to atomic layer deposition). The vapor phase deposition portion includes an introduction to vacuum, mean-free-paths, flux incident on surfaces, etc. Adsorption, desorption, surface diffusion, classical nucleation theory, wetting, surface energy effects, strain, and mechanisms of ion modification of materials are covered. Special issues related to epitaxial growth, critical thickness and mechanisms of strain relief are described. Discussion of evaporation include types of evaporation sources, flux distributions from evaporation sources and effusion cell design, and flux monitoring techniques including RHEED oscillations. Sputter deposition describes the basic mechanisms of sputtering, fundamentals of magnetron and rf sputtering processes, sputter yields, cosputtering, reactive sputtering, and methods of obtaining energetic fluxes of ions at a substrate to produce ion modification of the growth processes. Finally, basic chemical vapor deposition is described. This includes reaction and gas transport rate limited growth, hot and cold wall reactors, reactant selection issues, gas handling and safety, gas phase reaction processes, illustration of various CVD methods based on examples from GaAs deposition, selective CVD, and plasma-enhanced CVD are discussed. Finally a brief overview of the concepts of atomic layer deposition is provided.

Students should be aware that this is a very large range of topics to cover in the time available so the coverage of individual topics will necessarily be limited. Complete one or two day short courses on most of these topics are available from the American Vacuum Society and other organizations.

AM2 Technology Status and Critical Issues for Manufacturing High Volume Thin Film Photovoltaics: CdTe, Cu(InxGa1-x)Se2, Cu2ZnSn(SxSe1-x)4 and a-Si/nc-Si

Instructors: Dr. Tim Anderson, Dean of Engineering, University of Massachusetts Amherst, and Dr. Steven Hegedus, Scientist, Institute of Energy Conversion, University of Delaware

Thin film semiconductors have been investigated as absorber layers for large scale photovoltaic since the 1960's based on the promise of low manufacturing cost for large-area high-throughput PV modules. Three thin film absorber materials emerged in the 1980's as being technically and commercially viable for solar cells: CdTe, CuInSe2-based, and Si-based. More recently the Cu2ZnSn(SxSe1-x)4 kesterite material has received intense research as an earth-abundant absorber layer. The Si films are either amorphous or nanocrystalline while the other three are polycrystalline. Each is configured as a multilayer heterojunction device fabricated on glass, foil, or plastic substrates. Sustained worldwide research and development have significantly increased our understanding the materials chemistry and physics leading to advanced device structures and high-throughput processing at high yield. Each technology has the benefits common to thin films but each has specific challenges. In this tutorial, we will provide an overview of the basic processing sequence, device structures, manufacturing options, and key challenges for each thin film technology. Based on our 3 decades of direct involvement in thin film PV, we will review the evolution of each thin film technology into today's commercial success and identify critical issues limiting wider commercialization. The course is intended for graduate students, industrial researchers and technologists interested in an overview of the technologies as well has understanding the fundamental materials chemistry, device operation and characterization and process engineering.

PM5 Distributed Grid Integration using Solar PV Systems

Instructors : Michael Coddington and Blake Lundstrom, Distributed Energy Systems Integration Group, National Renewable Energy Laboratory and Dr. Ravel Ammerman, Teaching Professor, Electrical Engineering and Computer Science Department, Colorado School of Mines

Renewable energy resources are widely distributed geographically and are intermittent in nature, so they cannot be directly controlled and dispatched like the more traditional sources of generation. Large electrical power networks have been historically designed using centralized power generating stations supplying customer loads over interconnected transmission and distribution networks. Increasing the penetration level of distributed renewable energy sources requires adjustments to the existing operating procedure and design philosophy of large-scale power systems.

The workshop begins with a high-level overview of energy resources and distributed generation technologies, followed by an in-depth technical discussion of distributed generation interconnection issues. The intent of the workshop is to encourage audience interaction by soliciting input from all participants, using distributed generation interconnection case studies to facilitate discussions. We will cover: Energy System Basics - The Electric Power Grid, Distributed Energy Systems - PV Systems, Applicable Standards and Codes, Interconnection Processes and Procedures, Integrating Distributed Generation - Problems and Mitigation Techniques.
