Qian Cheng, Prof. Xihong Peng and Prof. Candace K. Chan Structural and Photoelectrochemical Evaluation of Nanotextured Sn-Doped AgInS2 Films Prepared by Spray Pyrolysis ChemSusChem 6
Tin best or tin pest? The role of Sn extrinsic dopants in chalcopyrite AgInS2 is investigated to understand their effects on the optical, electronic, and photoelectrochemical properties of this promising photoanode material. We found that at low amounts, Sn increased the AgInS2 carrier concentration and photocurrent, but was detrimental at higher dopant concentrations.
