technical field

The invention relates to the field of photovoltaic power generation, in particular to a mobile photovoltaic power generation device.

Background technique

Solar energy is a renewable energy source. Refers to the sun's thermal radiation energy, the main performance is often said that the sun's rays. In modern times, it is generally used to generate electricity or to provide energy for water heaters. Since the birth of life on earth, it has mainly survived on the thermal radiation provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as making salt and drying salted fish. With the decrease of fossil fuels, solar energy has become an important part of the energy used by human beings, and it has been continuously developed. There are two ways to utilize solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When a photon irradiates a metal, its energy can be completely absorbed by an electron in the metal. The energy absorbed by the electron is large enough to overcome the internal gravity of the metal to do work, escape from the metal surface and become a photoelectron. If pure silicon is doped with atoms with three outer electrons, such as boron atoms, a P-type semiconductor is formed. When the P-type and N-type are combined, a potential difference is formed at the contact surface, which becomes a solar cell. When sunlight hits the P-N junction, the holes move from the N-pole region to the P-pole region, and the electrons move from the P-pole region to the N-pole region, forming a current.

Existing photovoltaic power generation devices are generally fixed structures (such as the invention patent with patent publication number CN110768623A and the utility model patent with patent publication number CN209388191U), and are generally installed on roofs, color steel tile roofs, etc. It has the ability to be portable and mobile, and it does not have the ability to condense light.
