Potential fluctuations on CZTSSe solar cells admittance

, 2016
The Cu2ZnSn(SxSe1-x)4 (CZTSSe) kesterite compounds have proven their interest for next more friendly environment thin film solar cell technologies, compared to CuInxGa1-x(SSe)2 (CIGS) devices, currently in production, as they are composed of earth-abundant and non-toxic elements. However, an open-circuit voltage lower than expected is commonly reported

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 ...
