N-TYPE TOPCON TECHNOLOGY PV MODULES TECHNOLOGY
TOPCon solar cell technology is a high-efficiency crystalline silicon solar cell technology based on Tunnel Oxide Passivated Contacts (TOPCon). This technology involves forming an ultra-thin silicon oxide layer and a doped polysilicon layer on the surface of the silicon solar cell to improve its electrical performance and photovoltaic conversion efficiency. The core of TOPCon technology lies in utilizing the tunnel oxide layer to reduce minority carrier recombination at the interface, thus increasing the open-circuit voltage and fill factor of the cell.
Significant progress has been made in the research and development of TOPCon solar cells. For example, optimizing the thickness of the tunnel oxide layer, doping concentration, and structure of the polysilicon layer can further enhance the cell’s efficiency. Studies show that ultra-thin tunnel oxide layers and low defect densities are crucial for improving the passivation quality and efficiency of the cell. Additionally, advanced processes such as selective emitter (SE) technology and laser doping can achieve higher photovoltaic conversion efficiencies in TOPCon solar cells.
Another significant development direction for TOPCon solar cells is their integration with perovskite/crystalline silicon (c-Si) tandem solar cells. This tandem structure is expected to break the theoretical efficiency limit of single-junction solar cells and achieve higher photovoltaic conversion efficiencies. For instance, one study demonstrated a perovskite/c-Si monolithic tandem device using industrially produced TOPCon devices as the bottom cell, achieving an efficiency of 27.6%.
In terms of industrial production, TOPCon solar cell technology has made considerable progress. For example, using Low-Pressure Chemical Vapor Deposition (LPCVD) and Plasma-Enhanced Chemical Vapor Deposition (PECVD) technologies, high-efficiency TOPCon solar cells can be manufactured on a large scale. Furthermore, the use of tube PECVD equipment technology can further increase the production efficiency and reduce costs of TOPCon solar cells.
In summary, TOPCon solar cell technology significantly improves the electrical performance and photovoltaic conversion efficiency of silicon solar cells by introducing tunnel oxide passivated contact structures. As the technology advances and industrial production matures, TOPCon solar cells are poised to become one of the leading high-efficiency solar cell technologies in the future.
