Abstract

The invention discloses a novel ultraviolet-visible full-waveband absorbing material and a preparation method and application thereof. Components of the material comprise tin oxide, bismuth oxide, cadmium oxide, iron oxide, copper oxide and sulfur which are uniformly distributed in the composite material. The molar ratio of the components is SnO2: Bi2O3: CdO: Fe2O3: CuO: S = a: b: c: d: e: f, 2 <= a < = 3.5, 1.5 < = b < = 3, 1 < = c < = 2, 0.5 < = d < = 1, 0.5 < = e < = 0.8, and 0.5 < = f < = 0.8. The invention further provides a preparation method and application of the novel ultraviolet-visible full-waveband absorbing material. The nano-powder material is high in photoelectric conversion efficiency, the preparation raw materials are wide in source, cheap and easy to obtain, the preparation method is simple, and the cost is low. The nano-powder is easy to form by tabletting, and meets the processing requirements of solar window materials.

Description

technical field [0001] The invention belongs to the technical field of new energy materials, and relates to a novel ultraviolet-visible full-band absorbing material and its preparation method and application. Background technique [0002] With the continuous development of human society, non-renewable resources such as oil, coal, and natural gas are decreasing day by day. At the same time, the large-scale use of these non-renewable resources will cause great pollution to the environment. At the same time of sustainable development, it attaches great importance to the development and research of alternative energy and renewable energy. It is estimated that by 2025, photovoltaic power generation will account for 6%-21% of the total power generation of countries in the world. In recent years, international photovoltaic power generation has developed extremely rapidly. Developed countries such as the United States, Europe and Japan have formulated extremely large and exquisite ...
