p型TOPCon技术及其在高效晶体硅太阳电池应用的研究进展
RESEARCH PROGRESS ON p-TYPE TOPCon TECHNOLOGY AND ITS APPLICATION IN HIGH-EFFICIENCY c-Si SOLAR CELLS
摘要
Abstract
Tunneled silicon oxide passivation contact(TOPCon)c-Si solar cells are widely recognized as the next generation of efficient solar cell technology,and n-type TOPCon technology has become the mainstream solution for new production lines.Although the p-type TOPCon technology is more suitable for the p-type c-Si solar cell industry ecosystem,its development is slow due to factors such as difficulty in improving its key passivation contact performance and existing technical solutions not suitable for mass production.This paper is based on the importance of p-type TOPCon technology,providing a detailed introduction to the research progress of p-type TOPCon technology,and exploring the key scientific issues that constrain the improvement of passivation performance of this technology.From the research results at home and abroad,it can be seen that p-type TOPCon technology based on LPCVD technology and PECVD technology has made progress in passivation performance,achieving p-type TOPCon structures with the highest hidden open circuit voltage(corresponding to the lowest single-sided saturation current density)of 737 mV(2 fA/cm2)and 732 mV(approximately 5 fA/cm2),respectively.This has preliminarily demonstrated the potential for industrial application.The development of p-type TOPCon technology with industrial application value is of great significance for the development of c-Si solar cell industry and deserves further in-depth research by the entire industry.关键词
