Intelligent window based on ZnO-based transparent solar cell and preparation method of intelligent window

Abstract

The invention provides an intelligent window based on a ZnO-based transparent solar cell and a preparation method of the intelligent window. The intelligent window comprises a glass substrate layer, afirst latticed Ag nanowire electrode layer, an n-type ZnO thin-film layer, a P-type ZnMgO thin-film layer, a second latticed Ag nanowire electrode layer and an Ag nano particle thin-film layer, wherein the above layers are sequentially arranged from bottom to top. According to the invention, the Ag nano particle thin-film layer is adopted as a mask, and the transverse overgrowth is promoted. Thedislocation annihilation is induced, and the quality of the P-type ZnMgO thin-film layer is improved. Meanwhile, the Ag nano particle layer has the local-area surface plasma enhancement effect, so that the solar conversion efficiency is improved. The self-cleaning function is further realized, so that the later maintenance cost is further reduced. In addition, a single solar cell is formed by then-type ZnO thin-film layer and the P-type ZnMgO thin-film layer, so that the solar energy is absorbed and stored by the single solar cell. In addition, due to the fact that Ag particles have excellentreflection characteristics for infrared rays, Ag nanowires and Ag nano particles can reflect most of infrared rays indoors. The effect of winter warming is achieved.

Description

technical field [0001] The invention specifically relates to a smart window based on a ZnO-based transparent solar cell and a preparation method thereof. Background technique [0002] At present, smart windows are mainly divided into two types, one is electrochromic glass and the other is lowe glass. [0003] The former uses the electric field to control the color change of the glass and the amount of light passing through, so as to regulate the light. Although it can cool down in summer, it has no function of keeping warm in winter, and it cannot make good use of the sun. Light, the later cost is higher. [0004] Although Lowe glass can reflect back sunlight and indoor infrared light, it can only achieve the function of heat preservation and heat dissipation by reflecting sunlight or infrared light, and cannot make good use of solar energy. The cleaning of the smart window further increases the maintenance cost of the smart window in the later stage. Contents of the inv...
