Correlations of Capacitance-Voltage Hysteresis With Thin-Film CdTe Solar Cell Performance During Accelerated Lifetime Testing

Abstract

In this paper we present the correlation of CdTe solar cell performance with capacitance-voltage hysteresis, defined presently as the difference in capacitance measured at zero-volt bias when collecting such data with different pre-measurement bias conditions. These correlations were obtained on CdTe cells stressed under conditions of 1-sun illumination, open-circuit bias, and an acceleration temperature of approximately 100 ºC
