In this paper, we proposed and demonstrated the application of a rear busbar-parallel line opening pattern (BLOP) to reduce the series resistance and improve the PERC type cell efficiency. The proposed cells with BLOP gave an average efficiency of 21

The effect of material inhomogeneity on open-circuit voltage (V/sub OC/) of string ribbon Si solar cells is investigated by a combination of experimental results and a simple analytical model. Light beam-induced current (LBIC) measurements showed tha

This paper shows that one second (1 s) firing of Si solar cells with screen-printed Al on the back and SiN x anti-reflection coating on the front can produce a high quality Al-doped back-surface-field (Al-BSF) and significantly enhance SiN x -induced

Low-cost rear surface passivation has been a critical requirement for fabrication of cost effective high efficiency cells with local back surface field (LBSF) structures. This becomes even more important as we move towards next generation thin solar
