摘要
银浆是硅异质结太阳电池的重要材料,更低的体积电阻率和接触电阻、良好的附着力、优良的细线印刷性能及组件栅线抗腐蚀老化是其不断改进的方向.作为导电相,银粉的性能和含量对银浆有着至关重要的影响.该文基于低温固化银浆导电机理以及SHJ电池对银浆性能的追求,综述了银粉的振实密度、形貌、粒径、表面处理剂及其与有机物的适配.进一步探讨了纳米银粉和银包铜粉在SHJ太阳电池用低温银浆中的应用.
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.
