Outstanding Performance of N-type Solar Cells: Low temperature coefficient: The power temperature coefficient of n-type modules is -0.29%/ degree Celsius, which is lower than that of p-type cells at 0.35%/degree Celsius. This means that n-type modules are less affected by temperature and can maintain high power generation efficiency at different temperatures. High bifaciality: The bifaciality of N-type cells such as TOPCon can reach 85%, which is superior to the 70% of P-type cells such as PERC. This makes the N-type battery perform better in bifacial power generation and can generate electricity using more light . Low attenuation: The attenuation of N-type solar cells is even lower. The attenuation in the first year is =1%, and from the second year onwards, it is =0.4%. This means that their long-term power generation is more stable and the power generation throughout their entire life cycle is higher. High reliability: N-type solar cells perform exceptionally well in terms of mechanical strength and UV resistance. Its structure is symmetrical and the stress distribution is uniform, which can better disperse mechanical loads and reduce the risk of local stress concentration. Meanwhile, the front-back contact structure enhances the battery surfaces resistance to ultraviolet rays and slows down the degradation rate of the passivation layer. 50W Mono Solar Panel Specifications: Rated Power:50W Solar Cell:Monocrystalline Max.
