N-Type Monolike Silicon Bifacial Solar Cell: An Alternative Way of High Efficiency and Low Cost

33rd European Photovoltaic Solar Energy Conference and Exhibition; 595-599
China “Top Runner Program” leads to huge demand of high efficient solar cells in 2016. Every company is enthusiastic to develop their own high efficient solar cell technologies and products to keep competence in this field. Mono and multi PERC cells are the most popular among high efficient solar cells, however, the shortage of p-type mono wafer, Al2O3 and LIR tools hinder the cost and development of mono PERC. Besides, extra black silicon texturing and severe LID are still the issues for multi PERC. To solve the difficulties of mono and multi PERC, ntype monolike silicon bifacial solar cell is developed and presented in this article. The front cell efficiency up to 20.8% in average was realized by industrial-available process and facilities. Zero LID because of the intrinsic characteristic of n-type silicon wafers was proven without LIR process. Module power of 295Wp was achieved with 60 pcs cells and white backsheet. With the development and commercialization of double glass module, it is expected that low cost and high efficient bifacial solar cells will get more and more attention.
