Electrical & Computer Engineering Faculty Publications

This program has explored a number of novel materials for contacts to CdTe solar cells in order to reduce the back contact Schottky barrier to zero and produce an ohmic contact. The project tested a wide range of potential contact materials including TiN, ZrN, CuInSe₂:N, a-Si:H and alloys with C, and FeS₂. Improved contacts were achieved with FeS₂. As part of understanding the operation of the devices and controlling the deposition processes, a number of other important results were obtained. In the process of this project and following its conclusion it led to research …
