Outdoor camping is very popular nowadays, but do you know what we are most worried about in outdoor activities? Yes, what I am most worried about is the use of electricity. nowadays, people can say that they use electricity all the time, such as mobile phones, cameras, drones, lighting equipment, and even kitchen appliances, etc., so I believe that many friends who like outdoor camping have outdoor power like me. But no matter how powerful the outdoor power supply is, it can't stand the twists and turns for many days. How to replenish the electricity in the wilderness? At present, solar power generation is already a very mature technology, from national projects to a variety of emergency equipment, we can see the figure of camper solar panels.
The solar panel is a device that converts solar radiation into electricity directly or indirectly through the photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon", but due to the high production cost, its widespread use has some limitations. Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products.
A solar cell is a device that responds to light and converts light energy into electricity. There are many kinds of materials that can produce photovoltaic effects, such as monocrystalline silicon, polysilicon, amorphous silicon, gallium arsenide, selenium indium copper, and so on. Their principles of power generation are basically the same, and now take crystalline silicon as an example to describe the process of photo power generation. P-type crystal silicon can be obtained by doping phosphorus into N-type silicon, forming the Pmurn junction. When the light illuminates the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, which makes the electrons transition and become free electrons gathered on both sides of the Pmurn junction to form a potential difference. When the external circuit is turned on, under the action of this voltage, a current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting photon energy into electricity.
With the decrease in fossil fuels, solar energy has become an important part of human energy use and has been continuously developed.
Solar power generation is a new renewable energy, which has the advantages of both economic and environmental protection. the electricity generated by solar panels can be directly used to drive electrical appliances or charge batteries, and can also supply AC load through inverters. Therefore, countries have also begun to promote various applications based on solar power generation.
