Progress and prospectives of solution-processed kesterite absorbers for photovoltaic applications

Solar cells based on emerging kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) materials have reached certified power conversion efficiency (PCE) as high as 13.6%, showing great potential in the next generation of photovoltaic technologies because of their earth-abundant, tunable direct bandgap, high optical ab...
