Comparison of high and low injection cells for bifacial illumination

Abstract

A pilot production of bifacial cells was carried out using high resistivity and low resistivity bases, so that the cells work under high injection and low injection conditions respectively. When the performances of these cells were measured and compared with theoretical models, an agreement was found. It was concluded that the high injection cells show a more symmetric behaviour and that the low injection cells show slightly higher efficiencies, although good cells can be obtained with both bases.
