Fully processed CMOS Si wafers were reclaimed to make solar cells, while ensuring an acceptable efficiency loss of 15%. This project successfully developed a wafer reclaim process coupled with a solar cell fabrication process. The optimum efficiency obtained was 12.4% using prime wafers and surface texturing, while comparably processed reclaimed wafers were able to achieve 10.5% efficiency.
