TOPCon solar cell technology is a cutting-edge development that is significantly more efficient compared to PERC/PERT solar cells, which have a very similar structure. Panels of this type have higher efficiency, with conversion efficiency exceeding 25%. A lower temperature coefficient, less than 0.3%/°C, greatly improves their performance in a lot of extreme weather conditions.
The bifacial factor for PERC photovoltaic modules is typically around 70%. TOPCon solar panels have demonstrated a bifacial factor reaching 85%. Additionally, the structure of such solar cells is more resistant to dirt and debris.
- Half-cell type – double the number of cells
- TOPCon technology
- Monocrystalline silicon module
The structure of TOPCon N-type solar cells, used in Könner & Söhnen® panels, is more efficient than the P-type structure and is distinguished by greater resistance to dirt!
