Power supply device for solar mobile terminal mad of multiple photoelectrical material

Abstract

The invention discloses a solar panel, comprising two or more than two photoelectric conversion materials, wherein one of the photoelectric conversion materials is a multi-component compound photoelectric material; wherein the multi-component compound photoelectric material is gallium arsenide, indium phosphide, silicon carbide or gallium nitride. Moreover, the invention also discloses a solar mobile terminal power supply device comprising the solar panel, also comprising a solar battery working circuit; the solar battery working circuit comprises an output control module, a current detectingmodule, a display module and a battery. The solar panel according to the invention has high conversion rate and excellent performance price ratio, capable of providing stable pressure; being set on the mobile terminal, it can effectively improve the working efficiency of the mobile terminal.

Description

technical field [0001] The invention belongs to the field of solar cells, in particular to a solar mobile terminal power supply device composed of two or more photoelectric materials. Background technique [0002] At present, optoelectronic materials commonly used to make solar cells include monocrystalline silicon, polycrystalline silicon, multi-component compounds (such as gallium arsenide, indium phosphide, silicon carbide, gallium nitride), amorphous silicon, bio-solar materials, and nanocrystals. The characteristics of these photoelectric materials are very different. First, (1) From the perspective of photoelectric conversion efficiency, tests have shown that under standard light intensity, among the above photoelectric materials, the photoelectric conversion efficiency of the multi-component compound material is the highest. It can reach 24.88%, but the cost price of this material remains high. The photoelectric conversion material whose photoelectric conversion effi...

[0004] In addition, in daily life, the ambient light changes greatly. With the change of light, the current of the solar panel installed on the mobile terminal to charge the battery will be correspondingly reduced. The mobile terminal of the board, such as the light-energy mobile phone in the prior art, has no way to provide the information of the charging current change of the internal power supply device of the mobile terminal in real time, so for the user, it is impossible to grasp the charging situation in real time, and it is impossible to Adjust the position of the mobile terminal in time according to the real-time current information to change its light environment, and use light more effectively to charge the battery of the mobile terminal
