摘要

准单晶(类单晶)是一种众所周知的晶锭生长工艺，与传统的多晶硅太阳能电池相比，它具有显著提高电池性能的潜力。一般情况下，钢锭分为A、B、C区。在本报告中，由A区和B区制成的电池的平均效率与由DSS法通过酸纹理工艺制成的传统多晶电池相当。采用常规丝印技术加碱性织构工艺，C区细胞平均转化效率达19.08%，冠军细胞平均转化效率达19.40%以上。由于单晶片成本比单晶片低得多，采用碱织构工艺的准单晶片每Wp的成本可以达到260-265W的60个电池模块。

19.4% Quasi-mono cells by conventional screen printing technology

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.
