低成本银包铜浆料在HJT太阳电池中的应用研究
RESEARCH ON APPLICATION OF LOW COST SILVER COVERED COPPER SLURRY IN HJT SOLAR CELLS
摘要
Abstract
The high production cost restricts the development of HJT solar cells,with a relatively high proportion of metallization costs.Currently,the industry mainly achieves cost reduction of HJT solar cells through solutions such as silver coated copper slurry,non main grid technology,copper electroplating technology,and laser transfer technology.This paper describes the preparation of HJT solar cells using silver coated copper slurry with a silver content of 50%,and preparation into PV modules.The structure and tensile properties of the silver coated copper grid lines,the electrical performance of solar cells,and the reliability of PV modules are studied.The research results show that HJT solar cells and PV modules prepared using silver coated copper slurry have good performance,with a photoelectric conversion efficiency of 24.37%and a PV module CTM of 97.3%.The reliability tests are all qualified.In addition,compared with low-temperature silver paste,silver coated copper slurry can save the cost of silver paste,and if combined with non main grid technology,the cost of silver paste can be reduced by about 50%.关键词
