Product Introduction
HJT Solar Silver-Copper Paste is a key functional material that significantly reduces the manufacturing cost of HJT (Heterojunction) solar cells by partially replacing silver with copper.
Core Advantages
● Significant Cost Reduction
Copper prices are much lower than silver, and replacing silver with copper can reduce the paste cost by 20%-50%, bringing the HJT cell silver paste cost down to 0.04-0.06 CNY/W.
● Comparable Performance
The average conversion efficiency of the prepared HJT cell can reach over 24.37%, which is comparable to pure silver paste, with a cell-to-module (CTM) loss of approximately 97.3%.
● Process Compatibility
Suitable for the low-temperature preparation process of HJT cells and compatible with existing screen printing and 0BB (No Busbar) technology.
