▎ 摘　　要

NOVELTY - Ultra-narrow linewidth high-temperature sintered solar cell front-side silver paste comprises 5-8% nano-silver wire, 0-6% triangular nano-silver sheet, 0-3% nano-silver cube, 62-75% spherical micro-nano silver powder, 1-5% glass powder, and 7-15% organic carrier and further comprises 0-5% graphene. USE - The silver paste is useful in solar circuits. ADVANTAGE - The silver paste restricts line width and film thickness of the front silver paste produced in the later stage during application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the ultra-narrow linewidth high-temperature sintered solar cell front-side silver paste.
