Abstract
Cu$_{\mathbf {2}}$ZnSnS$_{\mathbf {4}}$ (CZTS) has been regarded as one of the most promising candidate for second generation solar cell and has attracted great attention recently. However, its current relative low efficiency limits its future development. In this contribution, partial Ag alloying method has been used to boost efficiency of CZTS solar cell. With Ag alloying, the microstructure has been improved and non-radiative recombination is suppressed. Consequently, the efficiency boost significantly from 7.8% to 8.8%.
