Which one is more efficient
The solar industry has witnessed significant advancements in technology, leading to improved efficiency and performance of solar modules. Two popular types of solar modules are N-Type Topcon and Mono PERC. In this blog, we'll explore why N-Type Topcon modules are more efficient compared to Mono PERC.
*N-Type Topcon Modules:*
N-Type Topcon modules use a different approach to solar cell architecture. Unlike traditional P-Type cells, N-Type cells use a negative charge carrier, which reduces electron-hole recombination. This results in:
- Higher efficiency (up to 22%)
- Improved temperature performance
- Increased longevity
*Mono PERC Modules:*
Mono PERC (Passivated Emitter and Rear Cell) modules are a type of solar cell that adds a passivation layer to the rear of the cell. This design improves efficiency by:
- Reducing electron-hole recombination
- Increasing reflectivity
However, Mono PERC modules still use P-Type cells, which have limitations compared to N-Type cells.
*Comparison:*
N-Type Topcon modules outperform Mono PERC modules in several areas:
- Efficiency: N-Type Topcon modules have higher efficiency rates (up to 22%) compared to Mono PERC (up to 19%)
- Temperature Performance: N-Type Topcon modules exhibit better temperature performance, resulting in higher energy yield
- Longevity: N-Type Topcon modules have a longer lifespan due to reduced degradation
*Conclusion:*
N-Type Topcon modules offer superior efficiency and performance compared to Mono PERC modules. While Mono PERC modules are still a popular choice, the advantages of N-Type Topcon modules make them an attractive option for those seeking higher efficiency and long-term reliability.
