Market Acceptance of LCPV and HCPV

Concentrator cells have been reaching increasingly impressive efficiencies, inspiring new interest in the high-efficiency, high-concentration approach. Currently, the record efficiency is 40.7 percent for a three-junction GaInP / GaInAs / Ge cell. From JX Crystals' perspective, its president Dr. Lewis M. Fraas sees the LCPV approach as fast to market with minimal risk. 'It is a simpler approach to understnd in terms of reliability and O&M because it is evolutionary from the traditional planar silicon module. Because of its simplicity, LCPV may be more suited to commercial building flat rooftops,' he recently told in an interview.
