Description

technical field [0001] The invention relates to the technical field of photovoltaic materials, specifically a novel photovoltaic material and a preparation method. Background technique [0002] Traditional photovoltaic materials refer to materials that can directly convert solar energy into electricity. Photovoltaic materials are also called solar cell materials, and only semiconductor materials have this function. Materials that can be used as solar cell materials include monocrystalline silicon, polycrystalline silicon, and amorphous silicon. There is monocrystalline silicon for space. Monocrystalline silicon, polycrystalline silicon, and amorphous silicon have been mass-produced on the ground. However, the current crystalline silicon photovoltaic materials have the problems of low utilization rate of sunlight and low energy conversion efficiency, and the current preparation method of crystalline silicon photovoltaic materials is relatively complicated, which is not con...
