1. Photovoltaic cells
Photovoltaic cells are a kind of photovoltaic devices that use different photocurrents generated by the different mobility of photogenerated electrons and hole pairs on semiconductors to generate electricity. The principle of photovoltaic power generation is mainly the power generation principle of solar radiation energy and the propagation principle of solar radiation energy. Solar radiation energy is converted into electrical energy through electrons, because solar energy is a visible light source that has no light radiation and does not need to be electrified, therefore, solar radiation is a natural clean energy that can be used by human beings. Photovoltaic cells are widely used in industrial production and building energy efficiency, especially in the field of industrial production and building energy efficiency.
2. What are the technical requirements for photovoltaic cells?
The technical indicators of photovoltaic cells include six aspects: light attenuation, light energy conversion efficiency, stability and reliability, cost, quality and life. Light attenuation refers to the loss of normal law in the relationship between solar radiation and battery output power. If the light loss is greater than a certain value, the performance of the battery will deteriorate after photoaging. Stability means that the continuous operation of photovoltaic cells is not affected by temperature fluctuations and will not be damaged or failed due to changes in external factors. Stability refers to the fact that photovoltaic cells control the flow of sunlight energy by physical means and can be stably converted into electrical energy.
