As the global demand for renewable energy continues to grow, solar cells have received widespread attention as an efficient and clean energy conversion method. Tunnel Oxide Passivated Contact (TOPCon) solar cells, as a new type of solar cell technology, have become a research hotspot due to their advantages of high efficiency, low cost, and ease of large-scale production. This technology effectively reduces interface recombination losses and improves the open-circuit voltage and fill factor of the solar cell by introducing an ultra-thin tunnel oxide layer and a polysilicon layer on the back of the cell, thus enhancing the photoelectric conversion efficiency of the solar cell. This article first introduces the research background of TOPCon solar cells, then provides a detailed theoretical analysis of their working principle, followed by a description of the key structures and preparation techniques for TOPCon solar cells. It also discusses the current research status and key issues of TOPCon solar cells, and finally summarizes and forecasts, providing reference and insight for future research on TOPCon solar cells.
