Abstract

Copper indium gallium selenide (CIGS) solar cells on thin film stainless steel substrates were evaluated by current-voltage-temperature (IVT) from 150K-350K to determine current transport mechanisms. Both dark and photo data at reverse and low forward voltages exhibited tunneling-like behavior. At intermediate forward voltages, diffusion or thermionic emission are suggested by an ideality factor close to 1.0. At higher currents and voltages there is a trend towards recombination or space change limited behavior.
