Характеристики





Conventional P-type cells use a boron-doped silicon substrate after initial illumination Boron-oxygen pairs are easily formed,trapping electrons in the silicon substrate to form a composite Center, resulting in photoattenuation, and N type cell silicon substrate doped with phosphorus, There is almost no loss of recombination center formed by boron-oxygen pair, and the photoattenuation is obtained Greatly optimized. On this basis, taking TOPCon technology as an example, tunneling The structure of the oxide layer further reduces the number of sub-surface recombination rates, pole The efficiency of cell conversion is optimized in large ground, and its upper limit can reach to 28.2%~28.7%.
TOPCon batteries apply cutting-edge efficient passivation contact technology, and upgrade the back of the battery to use a micro-nano tunnelling oxide layer and a carrier selective microcrystalline silicon film Functional structure. This innovative structure demonstrates a two-way improvement in passivation and conductivity, resulting in significant improvements in battery conversion efficiency and power generation performance.
