Studies of Basic Electronic Properties of CdTe-Based Solar Cells and Their Evolution During Processing and Stress: Annual Technical Report, 1 November 2005 - 31 October 2006

Research output: NREL › Subcontract Report

Abstract

We describe the results of our continuing study of deep electronic states controlling open-circuit voltage in CdTe/CdS thin-film solar cells (Task 1). The study includes: (1) analysis of factors affecting trap signatures derived from admittance spectroscopy and capacitance transients measurements, such as activation-energy capture cross-sections and trap-density estimates, and (2) comparativestudies of cells received from four different sources and prepared with significant variations in cell structure and processing procedures.
