In this study, we demonstrate that space-charge limited current (SCLC) is an intrinsic current shunting leakage in CdTe thin film solar cells. The SCLC leakage channel, which is formed by contact between the front electrode, CdTe, and the back electrode, acts as a metal-semiconductor-metal (MSM) like transport path. The presence of SCLC leaking microchannels in CdTe leads to a band bending at the MSM structure, which enhances minority carrier recombination and thus decreases the minority carrier lifetime in CdTe thin film solar cells. SCLC was found to be a limiting factor both for the fill factor and the open-circuit voltage of CdTe thin film solar cells. Published by AIP Publishing.
