ZnSe films prepared by the close-spaced sublimation and their influence on ZnSe/CdTe solar cell performance
CAS 2011 Proceedings (2011 International Semiconductor Conference)(2011)
摘要
This paper focuses on physical properties of ZnSe thin films and photovoltaic parameters of ZnSe/CdTe thin film solar cells. X-ray analysis and SEM images show that ZnSe films are polycrystalline and exhibit wurtzite-zinc-blende structure. ZnSe/CdTe solar cells show an efficiency of about 4.7%. The external quantum efficiency (EQE) for these cells shows that the shape of these characteristics depends on ZnSe layer thickness. The incorporation of Zn at the ZnSe and CdTe interface, for the first time, doubles the short circuit current density and improves the performance of ZnSe/CdTe thin film solar cells.
