What are the characteristics of photovoltaic cells and what are their techniques?
1. Basic characteristics of photovoltaic cells
1. Polarity of photovoltaic cells
Photovoltaic cells are generally made into P+/N-type structure or N+/P-type structure. P+ and N+ represent the conductivity type of the semiconductor material of the light layer on the front of the photovoltaic cell; N and P represent the conductivity type of the semiconductor material of the back substrate of the photovoltaic cell. The electrical properties of photovoltaic cells are related to the properties of the semiconductor materials used to make the cells.
2. Performance parameters of photovoltaic cells
The performance parameters of photovoltaic cells consist of open circuit voltage, short circuit current, maximum output power, fill factor, conversion efficiency, etc. These parameters are a measure of the performance of photovoltaic cells.
3. Volt-ampere characteristics of photovoltaic cells
A P-N junction photovoltaic cell consists of a shallow P-N junction formed on the surface, a strip and finger-shaped front ohmic contact, a back ohmic contact covering the entire back surface, and an anti-reflective layer on the front. When the cell is exposed to the solar spectrum, photons with energy less than the forbidden band width Eg do not contribute to the cell output. Photons with energy greater than the bandgap width Eg will contribute energy Eg to the battery output, and energy less than Eg will be consumed in the form of heat. Therefore, in the design and manufacturing process of photovoltaic cells, the impact of this heat on battery stability, life, etc. must be considered.
2. Tips for cleaning dust from photovoltaic cells
1. Under normal circumstances, photovoltaic equipment should be inspected every four years. First, all photovoltaic fans should be replaced. Then, according to the operating conditions, professionals should check the ripple condition of the DC circuit and check the appearance of the DC capacitors and AC capacitors. If there is no abnormality, use a special meter to test the capacitor capacity to determine whether to replace the capacitor.
2. The cleaning method is to start reinstalling the plug-in after the cleaning and maintenance are completed. Pay attention to the plug-in being inserted tightly and the secondary plug being plugged in properly. Check whether there is resonance between the fan and cover after power is turned on.
3. If the above conditions are normal, the photovoltaic power supply will continue to manually bypass the power supply load. When there is no load, professional technicians will individually debug the automatic bypass, rectifier and inverter for the photovoltaic power supply.
4. If the debugging is normal, the photovoltaic starts to switch from manual bypass to automatic bypass and then to the inverter for power supply.
5. Secondly, during dust removal, check whether the connectors and plug-ins are loose or not in firm contact.
