CIGS solar cells grown by a three-stage process with different evaporation rates

Solar cells based on polycrystalline Cu(In,Ga)Se 2 (CIGS) absorber layers have shown high potential for low cost photovoltaic energy conversion. Our group has achieved 18.1% efficient cells on glass substrates and 14.1% on flexible polyimide foils without antireflection (AR) coating. These results w...
