Abstract

Aluminum pastes (APs) with various silicate glasses (SGs) have been synthesized to enhance physical and electrical characteristics of screen-printed multi-crystalline silicon solar cells (SPMSSCs). The improved back surface field (BSF) and decreased tortoise-shell veins were demonstrated by suitably Si-Bi-B-doped Si-Bi-Ti-based oxide SGs in APs. The promoted mechanism could be attributed to the circulating track supplied from binary SGs softened in APs during co-firing. The achievement of a conversion efficiency improvement of more than 1.34% absolute from 16.01% to 17.35% in SPMSSCs with a binary Si-Bi-Ti of 1 wt% and Si-Bi-B of 3 wt% SGs in AP was explored.
