Lignin-based silver paste lifts HJT solar cell efficiency to 25.96%
Researchers at Guangdong University of Technology replaced 25% of petroleum-based epoxy resin with epoxidized lignin, boosting HJT cell efficiency to 25.96%.
Researchers at Guangdong University of Technology have developed a silver paste for silicon heterojunction (HJT) solar cells that replaces part of the petroleum-based resin binder with epoxidized lign...
