Abstract :
Quasi-mono (mono-like) is a well-known process for ingot growth that has potential to significantly increase cell performance over traditional multi-crystalline based silicon solar cells. In general, ingot is divided into A, B, C area. In this presentation, cells made from A and B areas average efficiency are comparable to traditional multi-crystalline cell made from DSS method by acid-texturing process. Cells from C area reached 19.08% conversion efficiency in average and over 19.40% in champion cell by using alkaline-texturing process with conventional screen printing technology. Quasi-mono wafers by alkaline-texturing process can be able to reach 260-265W 60 cells-module at lower cost per Wp due to much lower wafer cost in comparison with mono-crystalline wafer.
