Overview and Challenges of Thin Film Solar Electric Technologies

Research output: Contribution to conferencePaper


In this paper, we report on the significant progress made worldwide by thin-film solar cells, namely, amorphous silicon (a-Si), cadmium telluride (CdTe), and copper indium gallium diselenide (CIGS). Thin-film photovoltaic (PV) technology status is also discussed in detail. In addition, R&D and technology challenges in all three areas are elucidated. The worldwide estimated projection forthin-film PV technology production capacity announcements are estimated at more than 5000 MW by 2010.
