Nanoscale investigation of potential distribution in operating Cu(In,Ga)Se2 thin-film solar cells

Zhang, Zhenhao

Abstract:
Thin-film solar cells based on CIGS absorber materials show the highest power conversion efficiency among all kinds of thin-film solar cells. The distribution of the electrostatic potential in and between the materials in the solar cell has obviously a major impact on the superior performance of the device. This thesis reported on imaging of the electrostatic potential on untreated cross sections of operating CIGS solar cells using Kelvin probe force microscopy.
