Abstract

The invention discloses a high-generating-efficiency solar cell based on an electrochromic device and a making method of the solar cell. Improvement is conducted on the structure of the electrochromic device and a making technology, therefore, the electrochromic device has the self-power supply advantage, and the high-generating-efficiency solar cell based on the electrochromic device is made, wherein the solar cell is extremely high in photovoltaic energy conversion efficiency, the service life is prolonged, and the cold resistance is good. The method is simple and easy to operate, and industrial production is easy. At room temperature, a 1,000 W simulated sunlight source xenon lamp (Oriel 91192, USA) and a Keithly 2400source meter are used, the photovoltaic energy conversion efficiency is measured to range from 8.28% to 10.58% on the condition that the irradiation intensity is 100 W / cm<2>, and the irradiation area of the cell is 0.25 cm<2>, and after circulation is conducted 5,000 times, the photovoltaic energy conversion efficiency is measured to range from 8.01% to 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...
