Recombination Behaviour of Passivated Emitter and Rear Cell (PERC) Bifacial Silicon Solar Module under Different Illuminations

Bifacial silicon solar module has received considerable attention in recent years due to increasing the performance of photovoltaic plants. The passivated emitter and rear cell (PERC) bifacial silicon solar cell reduces contact recombination, and improves open-circuit voltage and cell performance. In this paper, recombination behaviour of passivated emitter and rear cell (PERC) bifacial silicon solar module under different illuminations was investigated. It is found that the J(01) of bifacial PERC solar module decreases with increasing irradiance intensity, and the J(02) is nearly constant from low injection to high injection. This shows that the PERC bifacial silicon solar module has more advantage in the field compared to Al-BSF solar module.
