The purpose of this subcontract is to (1) identify the challenges that ISET may face in the process of making a 'Lab to Large-Scale' transition for its ink-based non-vacuum process in production of thin-film CIGS solar cells and modules, and (2) develop workable solutions for these challenges such that they can readily be implemented in a large-scale processing line for CIGS modules. The primary objective of this research is to streamline ISET's ink-based non-vacuum process for fabricating efficient CIGS modules at a lower cost of module production of < $1.0 watt. To achieve this objective, ISET focuses R&D efforts on investigating topics that directly impact the ultimate cost of processing CIGS modules. These topics include (1) module output, and therefore, the solar cell and module efficiency, (2) overall process yield, which requires developing a process that offers a very high degree of repeatability for every manufacturing step, and finally (3) a process approach that maximizes the utilization of the materials used. In accordance with the above, this report will cover activity during Phase I in the investigation of methods for low-cost manufacturing and process development. Specific tasks cover four broad areas: (1) solar cell efficiency, (2) process control, (3) module integration, and (4) enhanced material utilization by recycling unused materials.
