Abstract

The invention discloses a solar power generation building based on an electrochromism device and a manufacturing method thereof. According to the solar power generation building and the manufacturing method, the structure and the manufacturing technology of the electrochromism device are both improved, and the self energy supplying function is added; in addition, the manufactured electrochromism device has the advantages that response time is short, photoelectric energy conversion efficiency is high, the service life is prolonged, and freezing resistance is good; in addition, the method is simple and easy to operate, and industrial production is facilitated. Under the conditions that the temperature is the indoor temperature, a 1,000-W sunlight source simulating xenon lamp (Oriel 91192, USA) is adopted, a Keithly 2400source meter is adopted, irradiation strength is 100 W / cm<2>, and the battery light receiving area is 0.25 cm<2>, the measured photoelectric energy conversion efficiency ranges from 8.28% to 10.58%; after 5000 times of cycles are carried out, the measured photoelectric energy conversion efficiency ranges 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 power generation building 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. 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 their infancy. [0003] In ...
