What are the classifications of photovoltaic cells and how to maintain them?
Photovoltaic cells can be divided into monocrystalline silicon photovoltaic cells, polycrystalline silicon photovoltaic cells, amorphous silicon photovoltaic cells, and copper indium selenide photovoltaic cells; the surface of the battery components should be kept clean, and the battery components should be inspected regularly. The following is a detailed introduction to the "photovoltaic cells" Classification and maintenance methods”.
1. Classification of photovoltaic cells
1. Monocrystalline silicon photovoltaic cells
Monocrystalline silicon photovoltaic cells are a type of photovoltaic cell that was developed earlier, has the highest conversion rate, and has a large output. The conversion efficiency of monocrystalline silicon photovoltaic cells has reached an average of 16.5% in my country, and the highest conversion efficiency recorded in the laboratory exceeds 24.7%. This kind of photovoltaic cell generally uses high-purity monocrystalline silicon rods as raw materials, with a purity requirement of 99.9999%.
2. Polycrystalline silicon photovoltaic cells
Polycrystalline silicon photovoltaic cells are photovoltaic cells based on polycrystalline silicon materials. Since polycrystalline silicon materials are mostly cast instead of the drawing process of single crystal silicon, the production time is shortened and the manufacturing cost is greatly reduced. In addition, monocrystalline silicon rods are cylindrical, and photovoltaic cells made from them are also wafers, so the plane utilization rate after forming photovoltaic modules is low. Compared with monocrystalline silicon photovoltaic cells, polycrystalline silicon photovoltaic cells appear to have certain competitive advantages.
3. Amorphous silicon photovoltaic cells
Amorphous silicon photovoltaic cell is a new type of thin film battery made of amorphous silicon as raw material. Amorphous silicon is a semiconductor with an amorphous crystal structure. Photovoltaic cells made with it are only 1 micron thick, equivalent to 1/300 of monocrystalline silicon photovoltaic cells. Compared with monocrystalline silicon and polycrystalline silicon, its manufacturing process is greatly simplified, silicon material consumption is less, and unit power consumption is also reduced a lot.
4. Copper indium selenide photovoltaic cells
Copper-indium-selenide photovoltaic cells are semiconductor films made of copper, indium and selenium ternary compound semiconductors deposited on glass or other cheap substrates. Due to the good light absorption performance of copper indium selenide cells, the film thickness is only about 1/100 of that of monocrystalline silicon photovoltaic cells.
2. Maintenance methods of photovoltaic cells
1. The surface of the battery component should be kept clean. Use dry or damp soft and clean cloth to wipe the battery component. It is strictly forbidden to use corrosive solvents or hard objects to wipe the battery component. Battery components should be cleaned when the irradiance is lower than 200W/m2. It is not advisable to use liquids with a large temperature difference from the components to clean the components.
2. The battery components should be checked regularly. If the following problems are found, the battery components should be adjusted or replaced immediately. The battery components have broken glass, scorched back plates, and obvious color changes; there are bubbles in the battery components that form communication channels with the edges of the components or any circuits; the battery component junction boxes are deformed, twisted, cracked, or burned, and the terminals cannot be used properly. touch.
3. The live warning mark on the battery component must not be lost.
4. For battery components with metal frames, the frame and bracket should be well combined, the contact resistance between the two should not be greater than 40, and the frame must be firmly grounded.
5. When working under no shadow conditions, when the solar irradiance is more than 500W/m2 and the wind speed is not more than 2m/s, the temperature difference on the outer surface of the same battery module (the area directly above the battery) should be less than 20°C. . Photovoltaic power stations with an installed capacity greater than 50kWp should be equipped with infrared thermal imaging cameras to detect temperature differences on the outer surfaces of battery components.
