710-725W Topcon Solar Panel

TOPCon, which stands for Tunnel Oxide Passivated Contact, is an advanced solar cell technology designed to enhance the efficiency and performance of photovoltaic cells. Here are some key points about TOPCon technology:

• Structure and Manufacturing: TOPCon cells are built with an n-type silicon substrate, which is more efficient and less prone to impurities compared to p-type silicon. A thin layer of silicon oxide is applied to the backside of the cell, followed by a layer of doped silicon.
• Efficiency: TOPCon cells have a theoretical maximum efficiency of up to 28.7%, which is very close to the theoretical limit for crystalline silicon solar cells (29.43
• Advantages:
  • Higher Efficiency: The advanced structure of TOPCon cells allows for better light absorption and reduced energy losses.
  • Lower Degradation: TOPCon cells exhibit lower degradation rates, including reduced Light-Induced Degradation (LID) and Potential-Induced Degradation (PID), which means they maintain their performance over a longer period24.
  • Compatibility: The manufacturing process for TOPCon cells is similar to that of PERC cells, allowing manufacturers to upgrade their production lines with minimal changes1.
