NUS Graduate School for Integrative Sciences and Engineering Research Project Write-up Title of Project : Advanced Thin Film Solar Cells-Materials and Devices Name of Supervisor : GONG Hao Contact Details: [email protected] DID: 65164632 Short Description Thin film photovoltaic technologies comprising CuInS2 (CIS), CuInGaSe2 (CIGS) and CdTe provide very high efficiency solar cells. However, such materials rely on elements that are costly and rare in the earth’s crust (e.g. In, Ga, Te) and are toxic (e.g. Cd). Hence, , using abundantly available non-toxic elements, seem to be the main issues in cost reduction. Kesterite structure Cu2ZnSnS4 (CZTS), having similar electronic structure of CIGS, is one of the most promising absorber layer candidates for low cost thin film solar cells. It is composed of earth abundant and non-toxic elements, promising price reductions. This project will be on the fabrication and study Kesterite structure low cost solar cell materials and devices. It is hoped that the progress of CZTS and CZTS thin film solar cells will lead to new paths for productive research.
