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 light energy generating device for an electric curtain. The device comprises a base, a light energy plate and a light gathering device, the light energy plate and the light gathering device are arranged on the base, and the light gathering device is arranged above the light energy plate; the light energy plate comprises a substrate, an n-type amorphous silicon layer, an i-type amorphous silicon layer, a p-type amorphous silicon layer and an anti-reflection layer which are sequentially arranged on the front surface of the substrate, and a nano copper particle layer andan aluminum electric field layer which are sequentially arranged on the back surface of the substrate, under the illumination condition of 500 Lux, the open-circuit voltage of the light energy plateis larger than or equal to 13.5 V, the working current of the light energy plate is larger than or equal to 22 mA, and the working voltage of the light energy plate ranges from 15 V to 17 V. By implementing the invention, a good light trapping structure can be formed on the back surface of the 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 electric curtain accessories, in particular to a light energy device for electric curtains. 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 electric energy...
