Abstract

High efficiencies of 19% CdTe solar cell devices were made using a thermal evaporation technique to deposit absorber layers of CdSe and CdTe. The absorber films were very high quality for a device fabrication, and with demonstrated high efficiency, it is a viable option to employ thermal evaporation in research and manufacturing. We also investigated four different interfaces scenarios of with and without MZO and CdSe in the device near front interface. The results clearly indicate that Se plays a key role in improving device performance, but the MZO is not necessarily required unless experiment goals demanded. Removing the MZO layer from the device structure and being able to use thermal evaporator for CdTe deposition will help with cost reduction in manufacturing.
