Abstract

Silver paste is an important material for silicon heterojunction SHJ solar cells. Lower volumetric resistivity and contact resistance, strong adhesion, fine line printing performance and corrosion aging resistance of module grid lines are the key technology points to improve. As conductive phase, silver powder have a critical influence on the performance of silver paste. Based on the conductivity mechanism and performance pursuit of low-temperature curing silver paste of SHJ solar cells, the tap density, morphology, particle size, surface treatment agents and its compatibility with organic matters of silver powder are reviewed. The application of nano-silver powder and silver-coated copper powder in low-temperature silver paste of SHJ solar cells are discussed.

Key words

silicon heterojunction solar cells / low-temperature silver paste / silver powder / surface treatment / tap density / silver-coated copper
