As a result, they begin generating electricity earlier in the morning and continue operating longer into the evening, thus extending the overall energy generation time. Compared to n-type BC solar panels, TOPCon panels show a power generation gain of 2.0%-7.18% over n-type BC, marking a significant improvement in efficiency and energy harnessing capability.

Conclusion:

In regions with inadequate daylight, like cloudy or foggy days or high-latitude areas in Northern Europe, South West of China, Japan, Korea, the focus on the efficient power generation capability of solar panels within limited sunlight hours highlights the importance of their low-light performance.  TOPCon's performance advantage in low irradiance scenarios is proven to work better, mainly due to the shunt resistance and FF advantages of n-type TOPCon. The relative efficiency change of n-TOPCon cells is higher than that of n-type BC cells, and the weak light performance of n-TOPCon cells is better than that of n-BC cells.
