On behalf of the Technical Program Committee, I invite you to submit an abstract on your latest achievements in photovoltaics research, development, and applications to the 38th IEEE PVSC. The PVSC is not just about the latest efficiency record either so whether it is a new module encapsulation, an novel characterization technique, or a new piece of science of the materials used in PV, we encourage your submissions in any topic related to PV. The chance to share and discuss these crucial PV developments in a timely and influential forum is what the PVSC is all about. Please contribute to the PVSC's tradition as the premier international conference on the science and technology of photovoltaics.

PV is a global industry, growing exponentially worldwide. Many key participants in the community have noted that, with strong cost drivers for a competitive technology, worldwide shipping of product will become increasingly difficult as it becomes a greater part of the cost of the devices. At the same time, electric power generation is intrinsically regional as long distance transmission is hard. Therefore this is a technology of worldwide interest and research and development in PV is distributed globally. I encourage participation from around the world in the 38th PVSC. This conference has traditionally had worldwide appeal and I hope that will continue in Austin. Travel to Texas is easy and Austin is a fun city, in addition to hosting the best PV conference in 2012.

We are continuing to promote two new technical areas that were initiated at the 35th PVSC. In recognition of the rapidly growing interest in organic photovoltaics and dye-sensitized solar cells, we are encouraging a special focus on Organic Photovoltaics, which is Area 6 at the 38th PVSC. The other special focus area is Area 8: Advances in Characterization of Photovoltaics. Here the desired focus will be on methods of measurement and analysis themselves, rather than on a particular photovoltaic material system. Where the characterization method is applied specifically to a given technology we plan joint sessions between that area and Area 8. By breaking out characterization methods separately, it is hoped that researchers will have more exposure to tools typically used for PV materials across areas of specialization. This will give researchers some 'new eyes' with which to look at their materials.

To have your paper considered for presentation at the 38th PVSC, please submit a 3-page evaluation abstract, and a short abstract no more than 300 words in length for display on the PVSC website, by the deadline below. Manuscripts are expected to be detailed enough to allow a competent technical review, a suggested format has been provided at the conference website. The preferred way to submit your abstract is via the 38th PVSC website at www.ieee-pvsc.org. Log in with your user name and password and carefully follow the instructions provided to upload your abstract successfully. Please be aware that the abstract and 3-page extended summary may constitute disclosure of what you include. Therefore be careful how you present proprietary or patentable information.

The deadline for electronic submission of the abstracts is February 6, 2012 at midnight Pacific Standard Time (UTC - 8 hours). Contributing authors will be notified of the acceptance status of their papers after March 10, 2012. For visa application purposes, an invitation letter will be issued at that time. Authors will be asked to confirm that they will be able to present their work at the conference and upload their manuscript by the due date of May 21, 2012 (2 weeks before the conference).

Submission to the IEEE Journal of Photovoltaics (J-PV): Authors submitting particularly high quality review abstracts, as evaluated by the program committee, will be offered the opportunity to directly submit a manuscript to J-PV. Authors who accept that opportunity will provide a full J-PV manuscript through the J-PV website (http://mc.manuscriptcentral.com/jpv) by May 21, 2012 as well as provide a 3-page abstract to the PVSC website (link) for conference attendees to electronically view. Papers submitted to J-PV will undergo a full peer review. Manuscripts accepted to J-PV will be published in J-PV as well as included in the conference proceedings DVD. For manuscripts rejected or withdrawn, the authors will provide a regular PVSC manuscript that will be archived in the conference proceedings and available on the IEEE Xplore website. This PVSC proceedings paper can be a modified version of the submitted manuscript or review abstract, having benefited from the J-PV review process. When the J-PV articles are finalized, a DVD copy of the full conference proceedings will be assembled and mailed to registered attendees.

Dear Colleagues,

On behalf of the technical program committee, it is our pleasure to invite you to submit papers in the area of Organic Photovoltaics (Area 6) to the 38th IEEE Photovoltaic Specialists Conference, to be held in Austin, Texas, the week of June 3, 2012.

Organic, hybrid inorganic/organic, and dye sensitized solar cells are rapidly advancing technologies that are beginning to demonstrate initial commercial viability. With efficiencies in OPV and DSSC approaching or exceeding 10% and new tandem devices approaching 9% these technologies may represent scalable PV technologies capable of achieving DOE cost goals. The flexibility to model and produce different donor/acceptor combinations including both organic small molecule and polymer as well as nanostructured inorganic materials stimulate a large diversity of possible approaches to realize the promise of efficient and highly stable devices. Many of the devices are excitonic in nature necessitating new models and understanding of the critical interfaces in the bulk heterojunction and the contacts.The symposium will focus on the examination of many of the key areas evolving in this diverse approach to solar energy.

The primary focus will in three primary areas that crosscut many of the themes in the broad set of devices combining inorganic and organic materials to developed high performance solar energy convertors with stability and low cost.

  1. New materials synthesis - this includes the topic of first principles design of new donor/acceptor materials, active absorbers and the enhancement of PV properties with QD and related inorganic materials. Themes are design and synthesis for increased red response, for tandem devices, and for stability
  2. Device Design and Interfacial Science and Engineering - as materials evolve so must the overall device structure as well as the interface to the outside world. This combination of device structure and interface design and characterization, crossing the boundaries of organic and inorganic materials is unique to this area.
  3. Lifetime and Scale-up - while OPV devices have shown very encouraging lifetimes, it is clear that to large scale production new processes, module designs and packaging will be need to be developed. As market penetration is aimed at building integrated PV and power generation this may require specific evolution for these applications. Key is establishing and predicting lifetime with a constantly changing materials set.

Dear Colleagues,

On behalf of the technical program committee, it is our pleasure to invite you to submit your Space Technologies (Area 7) related papers to the 38th IEEE Photovoltaic Specialists Conference, to be held in Austin, Texas, the week of June 3, 2012.

Advances in photovoltaic device performance for spacecraft applications over the past decade have been continuous and remarkable. However, spacecraft requirements of the power system continue to grow and power subsystems are still the most failure prone, thus there is much work to be done. Papers are sought that describe advancements in photovoltaic devices capable of high performance (efficiency, mass specific power, volumetric specific power, radiation stability, high temperature capability, LILT, low-cost, etc) as well as solar array designs suitable for these advanced devices. Also of interest are papers concerning cell, array and power system reliability, space environmental effects, and advanced protective materials for the space environment. To span the spectrum from fundamental research to applied engineering, we welcome papers ranging fromtheoretical studies to applied experimental efforts, including characterization and qualification as well as flight experiments and missions.

Area 7 has been divided into three subareas, as presented below. Submission of papers on detailed scientific research studies and visionary papers addressing the full range of these fundamental issues and technological challenges in the field are invited, including:

7.1: Space Devices and Materials
This subarea focuses on novel photovoltaic device approaches and recent developments for achieving high performance photovoltaic devices for spacecraft applications. Submissions may include (but are not be limited to) next generation multijunction solar cells, quantum enhanced devices, advanced cell materials and the spin-on of terrestrial photovoltaics for spacecraft applications (ie. thin film PV, etc). In addition, novel environmental protection technologies that enable longer on-orbit capability, high voltage operation, etc., are sought. Papers on characterization, modeling, and qualification of high efficiency solar cells are also welcome.

7.2: Space Systems
This subarea focuses on technology developments associated with integrating space photovoltaic devices into high performance spacecraft power systems, including blanket/module technologies (cell interconnects, advanced harnessing, modularity schemes, etc) and advanced solar array technologies.

7.3: Flight Performance and Environmental Effects
Analysis and results from on-orbit experimentation will be presented in this subarea. This includes behavioral data and analysis of high performance photovoltaic devices and systems exposed to the space environment as well as results from on-ground testing activities under realistic conditions. Papers examining solar cell degradation due to particle irradiation along with its modeling and flight prediction are encouraged. Also of interest are papers in which performance data is presented relevant to specific missions, such as near sun or deep space where solar cell performance has to be determined under extreme conditions (high intensity, high temperature and low intensity, low temperature, respectively). Finally, an emphasis will be placed on papers addressing photovoltaic device/array reliability.

Dear Colleagues,

On behalf of the technical program committee, it is our pleasure to invite you to submit papers in the area of Characterization Methods (Area 8) to the 38th IEEE Photovoltaic Specialists Conference, to be held in Austin, Texas, the week of June 3, 2012.

It is difficult to understand innovation in photovoltaics without the support of measurements and characterization. Measurements are needed at all different levels of R&D: from the investigation of the operating principles of solar cells to standards for the performance of installed PV systems. Understanding the relations between structure, physical properties, and the resulting PV performance is an exemplary problem in materials science and engineering and, in our opinion, one of the most critical to the development of the next generation of PV. Area 8 is intended for the presentation of the latest developments in the characterization of photovoltaics. We encourage members of the PV community to submit their contributions addressing the full range of scientific and technological challenges in the field, including the following topics:

8.1: Defects in Photovoltaic Materials and Solar Cells.
The presence of defects often limits the performance of solar cells and process yield. Relevant to this subarea are all methods for the characterization of defects and their influence on the PV performance, including (opto)electronic measurements, structure, composition, stress fields, and mechanical properties. This subarea includes both intrinsic defects of the PV materials and manufacturing defects associated with yield.

8.2: Advanced Methods and Instruments for the Characterization of Solar Cells and Modules.
In the last decade, improvements in methods and instrumentation in the field of the characterization of PV have been extraordinary. This subarea is targeted to an audience that is interested in getting a better understanding of the most recent developments in characterization methods and the capabilities offered by the latest generation of instruments available to the PV community and how their research can be assisted by these new capabilities.

8.3: Characterization Methods for the Photovoltaic Industry: In-Situ Measurements, Process Control, Defect Monitoring.
Process control typically requires continuous measurements integrated (and compatible) with the manufacturing equipment. These measurements, often required to be on contact and non-destructive, are essential to control manufacturing parameters and to yield and process performance optimization. In addition to this, it is important to develop feedback methods by which a process is controlled. This subarea includes both, novel methods and the application of existing methods in selected environments.

8.4: Challenges in the Characterization of Multi-Junction PV Devices
The concept of using more than one pn junction is one possible pathway to increase photovoltaic conversion efficiencies. It is successfully used in thin film photovoltaics as well as in III-V based solar cells. The internal series connection of several subcells, that cannot be accessed individually, adds complexity to the characterization. In addition spectral variations show a higher impact on the performance of these devices. Issues related to the characterization of multi-junction based photovoltaic devices are the topic of this subarea.

8.5: Performance, Reliability Testing, and Standards.
Standardization of measurements for the determination of the performance, reliability, and lifetime of PV modules and systems is increasingly important as the global installed PV power continues to expand exponentially. Of particular importance is the standardization of accelerated lifetime tests to estimate the PV performance over time. This subarea encompasses all such testing methods and standards as well as topics related to system components such as inverters, mounting hardware, resistance to harsh environmental conditions, and other issues.
