The production of solar cells is mainly based on semiconductor materials. Its working principle is to use the photoelectric effect of semiconductors. Silicon is a semiconductor material. Silicon solar cells are solar cells that use silicon as their base material. According to the crystal form of silicon material, silicon solar cells can be divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells.
Solar panels can be divided into:
1. Crystalline silicon panels: polycrystalline silicon solar cells, monocrystalline silicon solar cells.
2. Amorphous silicon panels: thin film solar cells, organic solar cells.
3. Chemical dye panels: Solar cells sensitized to dyes.
Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy by photoelectric effect or photochemical effect.
The lifespan of solar panels is determined by cell materials, tempered glass, EVA, TPT, etc. Generally, the lifespan of panels made by manufacturers who use better materials can reach 25 years, but over time Due to the influence of the environment, solar panel materials will age over time.
Detailed informationScopes of application:
1. Petroleum, Marine and Weather: Cathodic protected solar power systems for oil pipelines and tank valves, emergency and back-up power supplies for oil drilling. marine detection platforms and equipment, weather observation equipmentorological/hydrological, etc.
2. Lighting power: such as garden lights, street lights, portable lights, camping lights, climbing lights, fishing lights, black light lights, rubber tapping lights, lamps energy saving, etc.
3. Photovoltaic power plants: independent photovoltaic power plants from 10KW to 50MW, wind and solar (diesel) complementary power plants, various charging stations for large parking power plants, etc.
4. Solar buildings: The combination of solar power generation and building materials will make future large buildings self-sufficient in electricity, which is a major development direction for the future.
