Abstract

The invention discloses a solar cell with high power generating efficiency on the basis of an electrochromic device and a manufacturing method thereof. According to the solar cell, the structure and manufacturing process of the electrochromic device are both improved, so that the prepared solar cell with the high power generating efficiency on the basis of the electrochromic device has the advantages that automatic energy supply can be achieved, the conversion efficiency of optical and electric energies is high, the service life is prolonged, and the anti-freezing performance is great. The method is simple, easy to operate and capable of providing convenience for industrialized production. At the room temperature, a 1,000 W xenon lamp (Oriel 91192, USA) capable of simulating the sunlight as the light source is used, a Keithly 2400 source meter is adopted, and according to a measurement result under the situation that the radiation intensity is 100 W / cm<2> and the illumination area of the cell body is 0.25 cm<2>, the conversion efficiency of the optical and electric energies is 8.29-10.58%, and after the steps above are repeated 5,000 times, the conversion efficiency of the opticaland electric energies is measured as 8.01-10.56%.

Description

technical field [0001] The invention belongs to the field of solar power generation, and more specifically relates to a solar cell with high power generation efficiency based on an electrochromic device and a manufacturing method thereof. Background technique [0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are photoelectric semiconductor sheets that use sunlight to generate electricity directly. As long as it is illuminated by light, it can output voltage instantly and generate current when there is a loop. In physics, it is called solar photovoltaic (Photovoltaic, photo light, voltages volts, abbreviated as PV), or photovoltaic for short. [0003] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Thin-film solar cells that work on the photoelectric effect are the mainstream, while practical solar cells that work on the photochemical effect are still in th...
