Solar cell knowledge

Solar cell is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. It is also called "solar chip" or "photocell". As long as it meets certain illuminance conditions, it can output voltage instantly and in the case of loops. Generate current. In physics, it is called photovoltaic (Photovoltaic, abbreviated as PV), or photovoltaic for short.
Solar cells are devices that directly convert light energy into electrical energy through photoelectric effect or photochemical effect. Crystalline silicon solar cells that work with the photovoltaic effect are the mainstream, while the implementation of solar cells with thin-film cells that work with the photochemical effect is still in its infancy.

  1. Why solar street lights will become the main force of outdoor lighting?

    Why solar street lights will become the main force of outdoor lighting?

    In recent years, with the rapid development of the global economy, the infrastructure construction of various countries has become more and more perfect. Street lamps, as outdoor lighting equipment, have also moved from cities to rural areas, which greatly facilitates the daily lives of urban and rural residents. Careful friends may also have discovered that solar street lights can be seen everywhere and become the main force of outdoor lighting. So, why did solar street lights develop so fast and become the main force of outdoor lighting? Today, we will take a closer look.
    There are five main reasons why solar street lights are so popular: One is energy saving. As we all know, solar street lights use solar power to convert sunlight into electrical energy for lighting, which reduces our consumption of traditional electricity and saves a lot of electricity for the country every year. Energy-saving and emission-reduction is the general trend, so it has been strongly supported and promoted

  6. Do you choose lithium-ion batteries for solar street lights?

    Solar street light battery

    The wide application of solar street lights has greatly reduced the installation cost, and the advantages of high efficiency and energy saving have made it widely promoted and applied. The energy storage battery of solar street lights is also one of the very important components in the entire system. The general types are lithium iron phosphate. There are three types of batteries, lithium-ion batteries, and lead-acid batteries. Lithium-ion batteries and iron-lithium batteries are currently the most widely used. Lithium-ion batteries have high energy density, can be made smaller, and iron-lithium batteries have a longer life. This is the main reason why everyone favors lithium batteries. However, in practical applications, due to outdoor exposure and exposure to the sun, the possible high temperature and humid climate will greatly shorten the life of lithium batteries, and ultimately lead to serious

  7. How to install solar surveillance cameras

    How to install solar surveillance cameras

    The solar monitoring system is mainly composed of cameras, solar panels, controllers, and batteries. The installation steps of the traditional solar camera monitoring system are mainly divided into the following steps:
    The front-end camera equipment needs to be powered by wired methods such as solar panel arrays, controllers, battery packs, inverters, and switches. Installation is complicated, there are many steps, wiring is required, and maintenance is troublesome after problems occur. Many monitoring systems installed on both sides of the highway have become furnishings.

    With the development of science and technology and the maturity of the Internet of Things technology, the installation of solar camera systems is now less cumbersome. By inserting a mobile phone data card and accessing a 3G/4G network, real-time image transmission can be realized.

  10. Detection method of high-quality solar cells

    Solar cell

    Solar cells are divided into crystalline silicon and amorphous silicon. Among them, crystalline silicon solar cells can be divided into monocrystalline solar panels and polycrystalline solar panels. The efficiency of monocrystalline silicon is higher than that of crystalline silicon.

    How to detect the high quality of solar panels, we will explain from the appearance inspection, physical size inspection and appearance defect inspection of battery samples below.

    1. Visual inspection of battery samples

    We observe whether the color of the battery surface is uniform, whether there is mechanical damage, and whether the solder joints have oxidation spots.

    Whether the upper electrode of the battery and the bottom electrode of the battery have fallen off. Whether the anti-reflection film is peeling off or discolored. We also need to use vernier calipers and micrometers to measure the overall dimensions and thickness of the battery samples, which should meet the product
