Earth-Abundant Element Photovoltaics Directly from Soluble Precursors with High Yield Using a Non-Toxic Solvent

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 cou...

Zusammenfassung: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.
