During the TaiyangNews Virtual Conference on High Efficiency Solar Technologies 2022 – TOPCon, HJT and Beyond, Today & Tomorrow, Ma Jiayu, Product Manager Jolywood, shared the company’s proprietary plasma oxidation & plasma assisted insitu-doping deposition (POPAID) route of producing TOPCon for utility scale applications. It has helped the manufacturer increase n-type cell efficiency to the record level of 26.1% in R&D lab based on 182mm wafer size using its latest TOPCON 3.0. The key attributes of this upgrade technology are selective emitter and optimized metallization pattern, the crystallinity and thickness of poly layer and ARC coats. Since the technology was developed very recently, the company is continuing with TOPCON 2.0, both of which are based on PVD based deposition.
The 3-Day Conference took place from 23-25 November 2022, and had leaders from research, production equipment and materials supply as well as cell/module manufacturing and market analysis.
