Solar lighting generation device and preparation method thereof

Abstract

The invention provides a preparation method of a solar lighting generation device which has high light energy use ratio, flexible installation and wide application range. The device comprises a light pipe and a solar generation component, wherein the solar generation component is fixedly wrapped on the outer side of the wall of the light pipe, and the sunlight receiving surface of the solar generation component faces towards the inside of the light pipe. The solar generation component is formed by solar cell nano materials which are formed on the wall of the light pipe in a growth manner of physical package or chemical deposition and conductive layers arranged inside and outside of the solar cell nano materials. The solar lighting generation device has the advantages of simple structure, convenient installation and preparation, high use ratio of the solar energy and simple preparation method, solves the sunlight transmission and lighting problems, and increases the generation function, thereby being applicable to the lighting and generation fields of various buildings.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a preparation method of a solar lighting power generation device. Background technique [0002] With the advancement of science and technology and the improvement of public awareness of environmental protection, solar energy has attracted more and more attention as an inexhaustible clean energy. Current solar energy utilization methods include converting solar energy into electrical energy or directly using it as lighting, but there are certain defects in both of these methods: 1. Conversion of solar energy into electrical energy: many places have begun to use solar cells to generate electricity on a large scale, but the current Solar cells, whether they are crystalline silicon solar cells with strong light effects or amorphous silicon thin film solar cells with better weak light effects, must be installed in places where sunlight is directly irradiat...

Current solar energy utilization methods include converting solar energy into electrical energy or directly using it as lighting, but there are certain defects in both of these methods: 1. Conversion of solar energy into electrical energy: many places have begun to use solar cells to generate electricity on a large scale, but the current Solar cells, whether they are crystalline silicon solar cells with strong light effect or amorphous silicon thin film solar cells with better weak light effect, must be installed in places where sunlight is directly irradiated, which greatly limits their scope of use.

But the existing light-guiding material only transmits solar light to the room, and light loss occurs because the light passes through the light-guiding material in the transmission process (the inner wall of the light guide is a highly reflective material, and the reflectivity is generally more than 95% ), this part of the lost energy cannot be utilized
