Samenvatting:
N-type Metal Wrap Through (n-MWT) is presented as an industrially promising back-contact technology to reach high performance of silicon solar cells and modules. It can combine benefits from both n-type base and MWT metallization. In this paper, the integration of the MWT
technique with a commercial industrial bifacial n-type Si Solar cell (239 cm2) process is described. After the integration, 0.35% absolute efficiency gain was achieved, and Voc gain and Isc gain up to 0.42% and 2.45%, respectively, were obtained, mainly attributed to reduced shadow loss and surface recombination. Based on calculations, the anticipation of further improvements
for n-MWT solar cells, by taking better advantage of this integration, is also presented.
