研究目的
Investigating the recombination behaviour of passivated emitter and rear cell (PERC) bifacial silicon solar module under different illuminations.
研究成果
The PERC bifacial silicon solar module exhibits lower J01 and nearly constant J02 across different irradiance intensities compared to conventional Al-BSF solar modules, indicating better performance and temperature sensitivity. This makes PERC bifacial modules more advantageous in field applications.
研究不足
The study focuses on the recombination behaviour under different illuminations but does not explore the impact of other environmental factors such as temperature variations or long-term degradation.
1：Experimental Design and Method Selection:
The study involved theoretical analysis and experimental investigation of the recombination behaviour of PERC bifacial silicon solar modules under different illuminations. The double diode model was used for theoretical analysis.
2：Sample Selection and Data Sources:
P-type single crystalline silicon bifacial PERC solar cells were used, sorted by Berger simulator, and assembled into modules.
3：List of Experimental Equipment and Materials:
Solar simulator (XJTU-9), Berger simulator, tinned copper ribbon, ethylene-vinyl acetate (EVA), glass superstrate and substrate.
4：Experimental Procedures and Operational Workflow:
Electrical performance of the bifacial PERC solar module was measured under different illuminations. J01 and J02 were calculated using the double diode model.
5：Data Analysis Methods:
The relationship between J01, J02, and irradiance intensity was analyzed to understand the recombination behaviour.
