Abstract
The invention relates to a multi-color solar photovoltaic electrochromic device, comprising a first transparent base plate, a second transparent base plate opposite to the first transparent base plate, a photo-electrochromic element located on the first transparent base plate, and an allochroic element located between the first and second transparent base plates. The photo-electrochromic element comprises thin-film solar batteries and electrochromic materials on the thin-film solar batteries. Different potential differences exist between the thin-film solar batteries, and each thin-film solar battery comprises an anode, a photoelectric conversion layer and a cathode, wherein the anode and the cathode of each thin-film solar battery act as the anode and the cathode of the photo-electrochromic element. The allochroic element comprises two electrodes and allochroic materials thereon, wherein the cathodes of the thin-film solar batteries with different potential differences are respectively connected to the first and second electrodes of the allochroic element.
Description
technical field [0001] The present invention relates to a solar photoelectric electrochromics apparatus (photovoltaic electrochromics apparatus), and in particular to a multicolor solar photoelectric electrochromics apparatus. Background technique [0002] A so-called electrochromic or electrochromic element is an element composed of an electrically conductive substance that can produce a color change by applying an electric field or current to cause a reversible oxidation / reduction (redox) reaction. The manufacture of electrochromic components needs to meet the following characteristics, including: the colors presented at different potentials must be easily distinguishable, the color changes quickly and uniformly, the reversible color changes of the components should be able to repeat tens of thousands of times, and stability high. Common electrochromic elements include solid state surface confined thin film (surface confined thin film) electrochromic elements and solution...
