AbstractChalcopyrite-based solar cells have reached an efficiency of 23.35%, yet further improvements have been challenging. Here we present a 23.64% certified efficiency for a (Ag,Cu)(In,Ga)Se2 solar cell, achieved through the implementation of a series of strategies.

1 Introduction Kesterite Cu2ZnSn(S,Se)4 (CZT(S,Se)) seems a promising absorption layer material in thin-film solar cells due to the low-cost, earth-abundant, nontoxic, and environmentally friendly component elements.

In a recent study we showed that record open circuit voltage (1.1 V) can be obtained for wide band gap full Germanium kesterite Cu2ZnGeS4 (CZGS) thin film solar cells by substituting the standard CdS buffer with a Zn1−xSnxOy (ZTO) buffer layer grown by atomic layer deposition [N. Saini et al., Sol. RRL 2021, 2100837].
