Advances in Photovoltaics at NREL

Description: This paper discusses the critical strategic research and development issues in the development of next-generation photovoltaic technologies, emphasizing thin-film technologies that are believed to ultimately lead to lower production costs. The critical research and development issues for each technology are identified. An attempt is made to identify the strengths and weaknesses of the different technologies, and to identify opportunities for fundamental research activities suited to advance the introduction of improved photovoltaic modules.

Polycrystalline Thin Film Photovoltaics: From the Laboratory to Solar Fields

Description: The conclusions of this report are that: (1) many issues how thin-film solar cells work remain unresolved, requiring further fundamental R and D effort; (2) commercial thin-film PV module production reached 29% in 2005 in the US, indicating much more rapid growth than crystalline Si PV; (3) commercial module performance is increasing based on current knowledge, more R and D will lead to further improvement; and (4) stability of thin-film modules is acceptable ({le} 1% per year power loss) if the right manufacturing processes are used for manufacturing.
