USF-200S Solar Panel | Monocrystalline PERC (Passivated Emitter and Rear Contact)

The USF-200S is one of our solar panel models, alongside the LF100M and LF300M. Compared to other monocrystalline silicon solar panels, ours utilizes the more advanced and efficient monocrystalline PERC (Passivated Emitter and Rear Contact) solar cell technology. This technology combines the advantages of monocrystalline silicon and PERC (Passivated Emitter and Rear Contact) technologies, significantly improving solar cell efficiency.

What is Monocrystalline PERC (Passivated Emitter and Rear Contact)?

PERC is a technological improvement to solar cells that increases the overall efficiency of the cell by adding a passivation layer to the back of the cell. The role of the passivation layer is to reduce electron recombination and increase the electron recovery rate, thereby improving the photoelectric conversion efficiency of the cell.

How PERC works:

Emitter passivation: A passivation layer is added to the front (emitter) of the cell to reduce electron recombination and improve electron conduction efficiency.

Back contact passivation: A passivation layer is added to the back (back contact) of the cell to prevent electron recombination at the back contact, ensuring smooth electron outflow.

Enhanced reflection: A key feature of PERC technology is enhanced reflection. The back passivation layer not only helps reduce electron recombination but also reflects more unabsorbed light back into the silicon wafer, increasing light absorption and further improving conversion efficiency.

Advantages of PERC Technology:

Higher Photovoltaic Conversion Efficiency:

PERC technology effectively reduces the recombination of electrons and holes by adding a passivation layer, thereby improving cell efficiency. For monocrystalline silicon cells, using PERC technology typically improves photovoltaic conversion efficiency by 5%-10%.

Improved Performance in Low Light:

PERC technology improves cell performance in low-light or low-illumination environments, enabling greater power generation capabilities under conditions such as cloudy days, early mornings, and evenings.

Higher Stability and Durability:

The passivation layer reduces degradation of cell materials, improving the long-term stability and durability of the cell.

Lower Production Cost:

The implementation of PERC technology can significantly improve cell efficiency without significantly increasing costs, resulting in higher energy output and returns.
