Summary:

This is the Phase 1 Annual Technical Progress Report of a subcontract titled {open_quotes}Novel Two-Stage Selenization Methods for Fabrication of Thin-Film CIS Cells and Submodules.{close_quotes} The objectives of the program are the development of a cost effective process for CIS film deposition, optimization of various layers forming the CIS solar cell and fabrication of submodules using these processes and devices. During this first phase of the program the authors have completed their 1 ft² size processing capabilities and added to their facilities an in-line sputtering system that can handle up to 1 ft² size substrates. They have optimized the sputtering conditions for the Mo contact as well as the Cu and In films. Thickness uniformity of the Cu and In layers have also been optimized by masking the magnetron cathodes to obtain a variation of 3% throughout a ft² substrate. Using the resulting films, they have demonstrated their first large area CIS submodules with outputs of about 3W/ft². Addition of a computer controlled mechanical scriber to the fabrication facilities, and optimization of the large-area ZnO layers are expected to improve the power output of these submodules to over 5W/ft² shortly. In addition to the large-area submodule work, the authors have also carried out research aimed at the development of a non-vacuum processing approach for the growth of CIS layers. They have deposited films using this technique, and small-area cells with over 10% conversion efficiency have been demonstrated on such CIS layers.
