The crystal silicon solar cell combines hetero-junction technology, a combination of crystalline silicon and amorphous silicon, with back-contact technology where electrodes are aggregated on the back surface, widening the light-receiving surface and increasing conversion efficiency. NEDO and Kaneka are striving for solar power generation at a cost target of 14 yen/kWh in 2020 and 7 yen/kWh in 2030, combining high efficiency with high reliability.
