Abstract

The invention discloses a high generation efficiency solar cell based on an electrochromic device and a manufacturing method thereof; structure of manufacturing technology of the electrochromic device are improved so that the electrochromic device can supply energy for itself. The solar cell with high generation efficiency has the advantages that the manufactured photoelectric energy conversion efficiency is very high; the service life is prolonged; frost-resistance is good; also, the method is simple; the operation is easy; and industrialization production can be easily realized. At room temperature, the photoelectric energy conversion efficiency is 8.28-10.58% in the condition of a 1000W simulated solar light source xenon lamp (Oriel 91192, USA), keithly 2400 source meter, irradiation intensity of 100W / cm2 and cell illuminated area of 0.25cm2; and the photoelectric energy conversion efficiency measured after 5000 times of cycle is 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...
