Industrial applications of a novel technology for commercial multicrystalline silicon solar cells

Passivated emitter and rear contact cells are being more and more popular at present. In this paper, a novel technology for multi -crystalline silicon solar cells based on PERC are reported in which boron diffusion and SiNx dielectric layer are selected as the rear passivation. Industrial mass production of this technology has been implemented in a factory. Compared to ALBSF cells, about 0.6% efficiency gains was obtained. Most of the existing equipments for producing conventional ALBSF solar cells can be utilized in this technology, so this technology provides a more cost efficient solution for next generation solar cells.
