Problems solved by technology

(GranqvistClaes G. Electrochromics for smart windows: Oxide-based thin films and devices[J]. Thin Solid Films, 2014, 564: 1-38.) In addition, another difficulty is encountered in engineering design, due to this electrochromics The color-changing component needs to connect the external power supply with the central power control system to effectively control the component. It takes a lot of manpower and material resources to wire and connect the power supply when it is installed in the building, resulting in the installation cost required in the early stage. How to effectively reduce its dependence on external power supply to reduce installation costs has become a new research and development topic

Description

technical field [0001] The invention relates to an electrochromic device, in particular to a self-driven integrated photoelectrochromic component energy-saving glass that uses a perovskite solar cell as an electric drive source to systemically integrate the electrochromic energy-saving glass. Background technique [0002] In recent years, due to the massive use of non-renewable energy such as petrochemical energy by human beings, a large amount of carbon dioxide greenhouse gas emissions have resulted in a serious greenhouse effect. The average annual temperature of the earth has continued to rise after the industrial revolution, resulting in extreme climates, resulting in record-breaking summer temperatures. Therefore, how to effectively reduce the dependence on petrochemical energy and increase the proportion of renewable energy power generation has gradually become an important development direction of human society. However, in the transitional period when renewable energ...
