Abstract

Quasi steady state photoconductance (QSS-PC) and the "Suns- V oc" technique have been extensively used for characterizing silicon solar cells. QSS-PC has been used to determine the minority carrier lifetime, saturation current and surface recombination velocity. In this paper, we use both techniques to measure III-V tandem solar cells and III-V material, demonstrating the utility of the Suns- Voc for tandem devices and the ability to apply the QSS-PC measurements to the III-V materials, including GaAs and GaN. PC1D modeling is used to explain the experimental results.
