1. There is no need to worry about the solar panels contacting water, because the solar cells have been sealed and installed under the glass, and the back is laminated with EVA PET, so if there is any water outside, water. will not enter cells coming out from inside.
2. Even if the battery cells inside are filled with water, there is no need to worry, because the characteristics of solar cells may cause a short circuit. At most, there will be no power production during the short circuit. Once the short circuit is gone, it can be restored as before.
Sunlight shines on the p-n junction of the semiconductor to form. new hole-electron pairs. Under the action of the built-in electric field of the p-n junction, the holes are photogenerated to the p region, the photogenerated electrons flow to the n region, and the current is generated after the circuit is turned on. It’sThis is how photovoltaic solar cells work.
The light-heat-electricity conversion method generates electricity using thermal energy generated by solar radiation. Generally, a solar collector converts the absorbed thermal energy into steam as the working fluid and then drives a steam turbine. to produce electricity. The first process is a light-heat conversion process; the second process is a heat-to-electricity conversion process, which is the same as ordinary thermal power generation.
Detailed information
Features
1. Polarity of solar cells
General characteristics of silicon solar cells. It is transformed into a P+/N type structure or N+/P type structure. P+ and N+ represent the conductivity type of the semiconductor material of the front lighting layer of the solar cell. rear substratere of the solar cell. The electrical properties of solar cells are related to the properties of the semiconductor materials used to make the cells.
2. Solar cell performance parameters
Solar cell performance parameters include open circuit voltage, short circuit current, maximum output power, fill factor, conversion efficiency , etc. These parameters are a measure of the performance of solar cells.
