Product type
TOPCon solar cells, or Tunnel Oxide Passivated Contact solar cells, are a type of high-efficiency photovoltaic technology designed to convert sunlight into electricity. They are constructed using a silicon wafer with a thin layer of tunnel oxide and a passivated contact, which enhances the cell's performance by reducing recombination losses. This design allows for better light absorption and improved energy conversion efficiency compared to traditional solar cells.
| Efficiency range | 20% to 25% |
| Material | Monocrystalline silicon |
| Cell size | 156mm x 156mm or 158mm x 158mm |
| Temperature coefficient | -0.3%/°C |
| Power output | Up to 400W per module |
When selecting TOPCon solar cells, consider the efficiency rating, which affects the overall power output. It's important to specify the desired wattage and size based on your installation requirements. Additionally, inquire about temperature coefficients to ensure optimal performance in varying climates. Certifications such as IEC 61215 and IEC 61730 may also be relevant for quality assurance. Quantities should be determined based on your project scale, whether it's for residential, commercial, or utility applications.
