Abstract

original image

A new chemical route to Cu2ZnSn(SxSe1-x)4 based thin film solar cells has been developed using spin coating of commercially available molecular precursors from an environmentally friendly non-toxic solvent. 4.1% efficiency solar cells were achieved after selenization of Cu2ZnSnS4. This technique could provide simple, facile, and reproducible fabrication for efficient and large area solar cells.
