Problems solved by technology

However, adding a lithium battery will increase the volume of the controller; at the same time, the group control system also increases the production cost
In addition, in order to generate additional electricity, the volume of solar cells also needs to be increased. One is not beautiful enough, and the other will increase the cost.

Abstract

The invention discloses a preparation method of a light energy plate for an electric curtain. The method comprises the following steps: providing a substrate, texturing the substrate, cleaning with anaminosilane coupling agent solution, and sequentially forming an n-type amorphous silicon layer, an i-type amorphous silicon layer, a p-type amorphous silicon layer and an antireflection layer on thefront surface of the substrate to obtain a base sheet; then putting the base sheet into a copper particle sol solution, and forming a nano copper particle layer on the back surface of the substrate;and forming an aluminum electric field layer on the nano copper particle layer to obtain a finished product of the light energy plate. Correspondingly, the invention further discloses a light energy plate for an electric curtain, wherein the light energy plate is prepared by the preparation method. By implementing the invention, a good light trapping structure can be formed on the back surface ofthe light energy plate, and the spectral response capability of the light energy plate is effectively improved, so that the light energy plate can provide enough energy for driving the electric curtain under weak light conditions such as cloudy days and indoor light.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar panel used for electric curtains and a preparation method thereof. Background technique [0002] At present, sunshade products on the market can block sunlight by controlling the opening and closing of the curtain through the rotation of the motor. The power supply mode of the motor can be generated by external household power supply or by solar thermal radiation. Using the former power supply method requires wiring, which affects the appearance of the wall and increases the difficulty of installation. If the latter power supply method is used, it will not be able to obtain sufficient and stable electric energy when it is cloudy and cannot receive enough sunlight. In response to the above problems, the inventor proposed a technical solution for the combination of lithium batteries and solar panels in the previous application (202010297520.9), by storing the excess el...
