Power supply device for generating power through environment temperature

Abstract

The invention relates to a power supply device for generating power by using ambient temperature. Under certain specific conditions, some natural resources cannot be used for power generation. The device comprises a power generation box, a controller and a storage battery, wherein the power output end of the power generation box is connected with the power input end of the storage battery throughthe controller. The power generation box comprises a sealed box body, photovoltaic cell panels are attached to all the inner walls of the box body, cell pieces of the photovoltaic cell panels face theinterior of the box body, and a back plate is attached to the inner walls of the box body. After all the photovoltaic cell panels are connected in series, positive and negative electrodes are led outof the box body to be connected with the controller; and the box body is filled with a long-afterglow luminescent powder material. The photovoltaic cell panels are gallium arsenide solar cell panels.The long-afterglow luminescent powder is made of a europium dysprosium co-doped strontium aluminate long-afterglow material. Light emitted by electron excitation and compounding in the long-afterglowmaterial in a heat balance state is fully utilized and converted into electric energy through a photovoltaic device, other forms of energy sources are not needed, and the temperature difference doesnot need to be maintained. The device is simple in structure, reliable in operation and completely free of noise.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and relates to a power supply device that utilizes ambient temperature to generate electricity. Background technique [0002] At present, various energies in the environment can be used as energy sources, such as wind power generation, tidal power generation, solar power generation, hydropower generation, industrial waste heat power generation, etc. , it is impossible to use the above natural resources for power generation. [0003] Due to the existence of temperature, electrons in semiconductor materials are constantly undergoing the process of upward excitation and downward transition and hole recombination. As long as the ambient temperature is not absolute zero, these two processes always exist. The higher the temperature, the stronger the excitation and recombination, and vice versa, the weaker the excitation and recombination. At a certain temperature, upward excitation and downwa...
