Abstract

Crystalline silicon solar cells have long dominated the photovoltaic market due to their high conversion efficiency, stability, and mature industrial chain. This paper systematically reviews the research progress of crystalline silicon solar cells, with a focus on analyzing the working principles and characteristics of Passivated Emitter and Rear Contact (PERC) cells, Silicon Heterojunction (SHJ) cells, Tunnel Oxide Passivated Contact (TOPCon) cells, and Metal Oxide Selective Contact cells. It is found that PERC significantly reduces recombination losses through localized backside contacts. SHJ achieves full-area passivation by utilizing amorphous silicon and crystalline silicon heterojunctions. TOPCon combines ultra-thin oxide layers with doped polycrystalline silicon, offering both high passivation and process compatibility. Metal oxide selective contact technology simplifies doping processes through band engineering, but interface stability still needs improvement. Despite the efficiency improvements brought by these technologies, they still face challenges such as the high purity requirement of n-type silicon substrates for SHJ, the uniformity control of ultra-thin oxide layers in TOPCon, and the adhesion of metal oxide interfaces. High material costs, process complexity, long-term reliability, and the consistency of large-scale production remain challenges. Future research should further balance efficiency and cost, develop new passivation materials, optimize interface engineering, and promote the efficient transition of technologies to industrialization, to support the sustainable development of the photovoltaic industry.
