Silicon-sheet and thin-film cell and module technology potential: Issue study

The development of high-efficiency low-cost crystalline silicon ribbon and thin-film solar cells is a key element in achieving the goals of the US Department of Energy National Photovoltaics Program. This report summarizes the findings of an issue study conducted by the Photovoltaics Program Analysis and Integration Center at the Jet Propulsion Laboratory, with assistance from the Solar Energy Research Institute and the Flat-Plate Solar Array Project at the Jet Propulsion Laboratory. The study team interviewed leading researchers in crystalline-silicon ribbon and thin-film solar-cell technologies from Federal agencies and industry that conduct research funded both by the government and by private investment. The collected data identified the status of the technology, future research needs, and problems experienced. The data were also studied and evaluated to assess the potentials of present research activities to meet the Federal/industry long-term technical goal of achieving 15 cents per kilowatt-hour levelized PV energy cost. Recommendations for future research needs related to crystalline silicon ribbon and thin-film technologies for flat-plate collectors are also included.
