N-TYPE SOLAR CELL | The next generation solar cell technology

N-Type solar cells are an advanced photovoltaic (PV) technology designed for higher efficiency, improved durability, and superior performance compared to traditional P-Type cells. They are made from N-type silicon, which is doped with phosphorus to create a negative charge, reducing electron recombination losses and enhancing energy conversion efficiency.

These cells feature an optimized contact structure that minimizes energy loss, along with a thin silicon dioxide layer that further improves electrical performance. N-Type solar cells also resist Light-Induced Degradation (LID) and Potential Induced Degradation (PID), ensuring long-term reliability and higher energy yield. They perform exceptionally well in low-light and high-temperature conditions, making them ideal for residential, commercial, industrial, and utility-scale solar projects. With higher efficiency, better stability, and enhanced sustainability, N-Type solar cells represent the next generation of solar technology, providing maximum power output and long-term performance for clean energy solutions.
