Jinchen's first HJT PECVD passed production line verification
December 27, 2021 Author: Xiao Bei
PV-Tech News) Recently, Jinchen Co., Ltd.'s first heterojunction (HJT) PECVD equipment has achieved excellent performance-the battery conversion efficiency has been basically the same as that of Jinneng Technology's production line, and it has successfully passed the equipment process verification.
It is reported that the first HJT PECVD equipment independently developed by Jinchen has received strong support from the Jinneng team since it entered Jinneng Technology in June this year. After the installation and commissioning of the PECVD equipment was completed in early August this year, the production line of Jinneng Technology began to process wafers, and the efficiency of the first cell was 22.8%.
After more than three months of continuous hardware improvement and process optimization, the average efficiency of the cells produced by this equipment has reached 24.38% (open voltage Voc>745mv, fill factor FF>84.5%), and the efficiency distribution is very convergent. High, the average efficiency of the optimal batch is 24.55%.
Jinchen shares said that in the future, the company will continue to increase the HJT equipment industry layout, and is committed to achieving technological progress in the future of HJT battery line equipment quality and investment cost reduction.
According to reports, in order to continue to improve the technology and equipment R&D level of Jinchen, Jinchen has established a project to establish a "high-efficiency battery & high-efficiency component R&D laboratory", which is planned to be put into use in the first quarter of 2022, with a target research and development conversion efficiency of more than 25% of high-efficiency batteries Process and equipment technology (double-sided microcrystalline HJT, TOPCON, and new metallization solutions, etc.) and silver-less and silver-less component technology and equipment solutions, reserve new process methods, test data, research and development equipment, for high-efficiency batteries ( HJT, TOPCON) and supporting high-efficiency component technology from the laboratory to production, providing advanced and reliable technical solutions.
