Message from the Chairman

Dear Colleague

Thank you for your interest in ThermoPhotoVoltaics and Infrared Sensitive Solar Cells. The TPV-8 Conference will be held this year in coordination with and immediately following the ICSC-5 conference (see www.ICSC5.com and www.ICSC5.com/tpv.html). It will be held on November 20th in Palm Desert CA.

Topics will include:
Infrared Sensitive Cells
Infrared Radiant Sources
Spectral Control
Applications in Combined Heat and Power
Infrared Power Beaming
Space and Military Applications

Please submit abstracts by Sept 30 to lfraas@jxcrystals.com.
Follow the abstract format instructions given for the ICSC-5 conference.
The common theme for these 2 conferences is high power density photovoltaics. Therefore, please register for the ICSC-5 conference as the conference fee will cover attendance at both conferences.

Thank you.
Dr. Lewis Fraas

TPV-8 Conference Chairman

 

Background

The 8^th World Conference on Thermo photovoltaic (TPV-8) Generation of Electricity will be held immediately after the International Conference on Solar Concentrators for the Generation of Electricity or Hydrogen (ICSC-5). The ICSC-5 will focus on solar concentrator photovoltaic (CPV) systems.  Key to both conferences is the use of high power density photovoltaic chips to reduce the cost of photovoltaic electric power producing systems.  TPV and CPV systems are also complimentary in that solar systems work best during the day, in summer, and in warmer climates whereas TPV systems work best at night, in winter, and in colder climates. 

These 2 International Conferences will provide an opportunity to learn about cutting-edge research, industrialization and commercialization of high power density photovoltaic systems. The conference will emphasize in-depth technical discussions on the science, engineering, and economics of systems that convert concentrated radiation to electricity or hydrogen, with primary emphasis on photovoltaic (PV) technologies.

Very high-efficiency solar cells — now over 40% — have recently been developed using multi junction concentrator cell technology. This development has increased the potential of solar concentrators for generating low-cost electricity or hydrogen. Solar electric concentrators could dramatically overtake other PV technologies in the electric utility marketplace because of the low capital cost of concentrator manufacturing facilities and the larger module size of concentrators. The current feed-in tariff conditions in Spain, Italy, Japan, and the positive perspectives in USA and Greece provide the opportunity for development of large power plants, long assumed to be the natural market for PV concentrators.  The development of these high efficiency solar cells has also led to the development of infrared sensitive PV cells.  These cells are now enabling for TPV systems.  There are other applications as well for these IR cells including, for example, solar hybrid lighting and infrared power beaming applications.

Around the world, researchers and engineers are developing high power density PV technologies for entry into the electricity generation market. The accelerated activity in high-efficiency terrestrial cell R&D and manufacturing in the last three years, coupled with industrial developments at key concentrator PV companies, promise an exciting conference for researchers, developers, and investors alike.

 

Presenters

Call For Papers

Papers and oral presentations are invited in the listed topic areas and will be judged solely on the basis of an abstract that clearly explains the significance of the work. The research must be new, of high quality, and contribute significantly to the knowledge of high power density photovoltaic devices and systems.

The conference will cover the interests of university research, industry research and development, user communities such as electric utilities, and government-funded research. The focus will be on science and technology of high power density photovoltaic devices and systems technologies and topics can range from exploratory research through applied research, engineering, technology development, and application.

Accepted abstracts will appear on the conference Web site. Copies of both oral and poster presentations will be submitted at the conference for a CD-ROM and AIP compilation of all presentations. Acceptance of the abstract does not guarantee acceptance of the presentation for the CD-ROM. The conference language will be English. Abstracts are solicited now through September 12th, 2008.
