Low‐Temperature‐Processed Cu2ZnSnS4 (CZTS)/CdS/1D‐Titania Tandem Photoanode with Effectual Photoelectrochemical Response

A molecular precursor–based Cu2ZnSnS4 (CZTS) layer deposited at very low temperature (100 °C), without any sulfurization step, over a CdS/1D titania tandem photoanode is explored for its photoelectrochemical (PEC) application. Further, the CZTS‐based tandem photoanode is optimized by varying the com...

Description
Summary:A molecular precursor–based Cu2ZnSnS4 (CZTS) layer deposited at very low temperature (100 °C), without any sulfurization step, over a CdS/1D titania tandem photoanode is explored for its photoelectrochemical (PEC) application. Further, the CZTS‐based tandem photoanode is optimized by varying the composition of Cu and Zn in the molecular precursor solution. With enhanced optical absorption in the visible region and also more efficient separation of the photogenerated charge carriers, the tandem photoanode exhibits an almost 20 times higher PEC response compared to 1D TiO2, on par with the best in the relevant literature. Herein, a scalable solution route for good quality Cu2ZnSnS4 thin films at ultralow temperature and ≈180% enhancement in the photoelectrochemical response shown by the tandem photoanode as compared to 1D titania are demonstrated.
