Household glass based on 3D printing nano-diamond transparent thin-film battery and preparation method

Abstract

The invention discloses household glass based on a 3D printing nano-diamond transparent thin-film battery and a preparation method. The household glass comprises glass and an anode layer, a P-type nano-diamond thin film, a PN junction layer, an N-type nano-diamond thin film and a cathode layer sequentially arranged on the glass close to the indoor side. The method comprises the following steps of: (1) cleaning the glass for later use; (2) preparing a Ti / SnO2 thin-film electrode as an anode for later use; (3) establishing a 3D digital model of the glass according to the size and shape of the glass, and printing P-type and N-type nano-diamond thin films; and forming the PN junction layer by use of a diffusion tube to obtain a battery substrate; (4) preparing a ZnO / Al transparent thin-film battery as a cathode by FDM-based 3D printing equipment on the battery substrate to obtain a nano-diamond transparent thin-film battery; and (5) performing lamination encapsulation of the glass, anode and nano-diamond transparent thin-film battery through a flexible polyester film.

Description

technical field [0001] The invention relates to a household glass capable of utilizing solar energy, in particular to a household glass based on a 3D printed nano-diamond transparent film battery and a preparation method thereof. Background technique [0002] Solar cells are currently mostly prepared using tetravalent semiconductor silicon materials, and the preparation process consumes a lot of energy and causes high pollution. However, diamond is also tetravalent. Now people have mastered the method of preparing nano-diamond in the laboratory with low energy consumption and no pollution, so artificially prepared diamond is widely used in clothes, shoes and hats. Diamond has excellent physical properties such as high thermal conductivity, high hardness, high breakdown field strength, low friction coefficient, low dielectric constant and wide band gap, and high mobility of electrons and holes, and has good optical transmittance and chemical properties. Stability, so that di...

Problems solved by technology

[0003] In the existing home solar energy collection, a large area of ​​uniform solar panels is usually installed on the roof to collect solar energy, but this method is expensive and the efficiency is mediocre

The solar glass disclosed in the prior art uses paint to absorb sunlight and then transmits the light at different wavelengths to the solar cells installed on the edge of the glass. Although the light transmittance is not affected by the use of transparent materials, its stability is poor. The path is long, the efficiency is low, and only a concept has been proposed at present, which is only at the level of theoretical research
