Description

technical field [0001] The invention relates to the technical field of photovoltaic material preparation, in particular to a nanocomposite photovoltaic material and a preparation process thereof. Background technique [0002] The use of solar energy for photothermal and photoelectric conversion and the development of solar cells have become an important way to solve the worldwide energy crisis and environmental pollution. The current industrialized solar cells are mainly compound solar cells such as Si-based and CIGS, but the preparation process of Si-based solar cells is complicated and the pollution is serious. For other compound solar cells, indium and selenium are relatively rare elements, and cadmium is highly toxic. . Therefore, the development of such batteries is bound to be limited. Because of this, in recent years, it is necessary to develop new semiconductor solar cells in consideration of environmental pollution and other issues. [0003] The current photovolt...
