Photovoltaic Solar Energy Conversion: Materials and Technology Challenges

摘要

The direct conversion of solar energy to electricity by photovoltaic devices is on track to become a leading competitor for next generation green power production. Although wafer-based crystalline Si is currently the dominant material for solar cells and it is expected to remain for at least a decade as the major technology, Si might not be so able to meet long-term cost goals.rnThin film solar cells based on amorphous Si (a-Si), Cu(lnGa)Se_2 (CIGS) and CdTe and nano/micro/poly-Si are gaining a strong momentum for their prospective high potential for cost reduction and quality improvement and are now becoming to experience an increasing weight on the market.
