Suppressing back-interface recombination in CZTSSe solar cells via SiO2 nanoparticle-induced discrete local contacts

Nano Research
The severe back interface recombination remains a major performance limiting factor in Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. In this work, SiO2 nanoparticles deposited on Mo substrate by spin-coating were used to create discrete local contact points to ...
