Problems solved by technology

[0006] There are some problems in this integrated self-powered electrochromic device: on the one hand, the dye layer in the device will reduce the transmittance of the device; on the other hand, as an integrated device, the electrochromic process and the photoelectric conversion process are carried out simultaneously There will be some impact. For the electrochromic layer, the absence of ion storage layer in the integrated device will reduce the electrochromic properties, and the photoelectric conversion efficiency is low

Abstract

The invention belongs to electrochromic technologies, and relates to an intelligent remote-control self-power electrochromic window and a method for manufacturing the same. The intelligent remote-control self-power electrochromic window mainly comprises a solar cell, a voltage controller, a light sensing switch, an electric energy storage and an electrochromic window. Steps for manufacturing an electrochromic device include sequentially depositing various functional layers on transparent substrates and carrying out laminating and sealing assembling; preparing counter electrodes; preparing working electrodes; preparing gel electrolyte; assembling the device. The intelligent remote-control self-power electrochromic window and the method have the advantages that the electrochromic window can have electrochromic functions without additional voltages, the electrochromic degree of the electrochromic window can be regulated, accordingly, the intensity of light from outdoor environments to indoor environments can be dynamically regulated and controlled, and the intelligent remote-control self-power electrochromic window can normally work by the aid of electric energy stored by the electric energy storage without sunlight at night or on cloudy days.

Description

technical field [0001] The invention belongs to electrochromic technology, and relates to an intelligent remote control self-powered electrochromic window and a manufacturing method thereof. Background technique [0002] In this era when energy issues become the focus, it is not only necessary to develop new energy sources, but also to save existing energy sources. The energy consumption applied to buildings accounts for 30%-40% of the world's total energy consumption, and these energy sources are mainly used for heating, cooling, ventilation and electrical appliances inside buildings. Windows are the weak link in the building when it comes to heat dissipation. In order to improve comfort, the area of ​​windows is getting bigger and bigger. In some commercial buildings, the area occupied by windows is equivalent to the area of ​​walls. A large part of energy is wasted through glass diffusion. Reducing energy consumption of windows has become a market demand. [0003] In 19...
