Solar monocrystalline silicon single-sided N-TOPCon module is a new type of photovoltaic module, which uses monocrystalline silicon as the substrate, and adds N-type passivation layer and TOPCon technology to it. The N-type passivation layer can effectively improve the electron transport performance of the component, reduce the recombination loss of electrons, and improve the photoelectric conversion efficiency. The TOPCon technology can increase the photoelectric conversion rate by forming a transparent conductive film on the surface of the crystal. This module has higher efficiency and lower photosensitivity degradation rate in the solar field, can better adapt to various lighting conditions, and has a longer service life. Therefore, solar monocrystalline silicon single-sided N-TOPCon modules have broad application prospects in solar power generation systems.High conversion efficiency: The use of N-TOPCon structure can improve the photoelectric conversion efficiency, so that the module can make full use of solar energy and generate more electricity. High-performance stability: Due to the high-quality monocrystalline silicon material, the module has good weather resistance and stability, and can run stably for a long time. Size flexibility: Solar monocrystalline silicon single-sided N-TOPCon modules can be customized according to requirements, and modules of different sizes and powers can be produced to suit different application scenarios.Q1: How could I buy the solar panel if there is no price in the website?
