Speaker: Dr. Steven S. Hegedus, Institute of Energy Conversion, University of Delaware
In his talk, Dr. Hegedus, a 30-year solar cell research veteran, provides an overview of the existing status of today's solar technology platforms and manufacturing issues, as well as provide viewers with his perspective looking 3 to 5 years into the future. He discusses cadmium telluride (CdTe) and copper indium gallium selenide (CIGS) thin-film technology. He also provides up-to-date results for advanced crystalline silicon (c-Si) high efficiency cell technology concepts such as the amorphous/c-Si heterojunction, all-back-contact cells, selective emitters and laser-fired contacts. Finally, he briefly describes his lab's current work on addressing critical issues in CIGS and c-Si cell technology.
Dr. Hegedus has been a member of the research staff at IEC at the University of Delaware, the world's oldest photovoltaic research laboratory, since 1982. He co-edited the 1st and 2nd editions of the "Handbook of Photovoltaic Science and Engineering" (Wiley 2003, 2011) and is a co-editor of the journal "Progress in Photovoltaics."
