Abstract

High densities of both bulk and interface states were found in CdZnS/CuInSe₂ thin film devices. Deep level transient spectroscopy studies showed that air baking removes minority carrier levels at 39 meV and 78 meV. Light induced capacitance indicated that charging of deep interface states reduced the CuInSe₂ diffusion potential. A model was proposed using interface recombination as the only diode current mechanism. This model relates interface state charging to a reduced open-circuit voltage.
