Coating for converting optical energy into electric energy and glass assembly

Abstract

The invention provides a coating for converting optical energy into electric energy and a using method of the coating. The coating comprises 90-95% of titanium dioxide nano particles, 1-5% of cadmium sulfide or cadmium selenide, 2-8% of water and 0.5-2% of alcohol. The surfaces of the titanium dioxide nano particles are coated with cadmium sulfide or the cadmium slenide and then suspended in mixed liquid of the water and alcohol to form thick mash; transparent conducting material is coated with the thick mash and exposed in light, and then electricity can be generated. The invention further provides a glass assembly converting the optical energy into the electric energy, and the glass assembly is coated with the coating. Through a large number of experiments, the formula proportion of the coating is optimized, so that solar energy is effectively converted into the electric energy, besides, optical energy of indoor lamp light, candlelight and others is converted into the electric energy, the optical energy conversion rate is high, raw material is cheap, the using quantity is small, and only one thin layer is needed, so that demands for silicon are reduced, and cost is greatly saved.

Description

technical field [0001] The invention relates to a coating, in particular to a coating for converting light energy into electric energy and a method for using the same, and also relates to a glass component for converting light energy into electric energy. Background technique [0002] The energy of solar energy is the energy from celestial bodies outside the earth (mainly solar energy). It is the huge energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperature. Most of the energy needed by human beings comes directly or indirectly from the sun. Fossil fuels such as coal, oil, and natural gas that we need for life are all formed by plants and animals buried in the ground after a long geological age after converting solar energy into chemical energy through photosynthesis and storing it in the plant body. In addition, water energy, wind energy, wave energy, and ocean current energy are all converted from solar energy. [0003] There are two types of ...

Problems solved by technology

[0004] However, most of the existing solar power generation needs to use special equipment, such as silicon solar cells, and the input cost is relatively high, and most of the solar power generation equipment can only use solar energy when it is directly exposed to sunlight, and the utilization time of sunlight is short

The U.S. "Popular Science" magazine disclosed a solar nano-coating in 2007. This solar nano-coating uses carbon nanotubes and buckyballs as main materials, and it can generate electricity by coating it on walls, cars, etc., but its The conversion rate of solar energy is only about 1%, and the utilization rate of solar energy is too low, so it must be installed outdoors, and the indoor utilization rate is extremely low
