A Solar GEL Battery is a device that converts light energy directly into electrical energy by photoelectric effects or photochemical effects. The principle of Solar GEL Batterys
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on. This is the photoelectric effect of the working principle of Solar GEL Batterys.
First, the solar power There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
1, light - heat - electricity conversion through the use of solar radiation generated by thermal power, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The latter process is the light-heat transfer process; the latter process is the heat-to-electrical conversion process, as is the case with ordinary thermal power generation. The drawback of solar thermal power generation is that the efficiency is very low and the cost is high, Power station 5 to 10 times a 1000MW solar thermal power plant needs to invest 20 to 25 billion US dollars, an average of 1kW investment of 2000 to 2500 US dollars. Therefore, at present only small-scale application to special occasions, and large-scale use in the economy is very cost-effective, can not compete with ordinary thermal power plants or nuclear power plants.
2, optical - electrical direct conversion method The way is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, optical - electrical conversion of the basic device is the Solar GEL Battery. The Solar GEL Battery is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode turns the solar energy into electricity. Current. When many batteries in series or in parallel can become a relatively large output power of the Solar GEL Battery array. Solar GEL Batterys are a promising new power supply, with permanent, clean and flexible three major advantages of Solar GEL Batterys long life, as long as the sun exists, Solar GEL Batterys can be an investment and long-term use; and thermal power, nuclear power generation Compared to Solar GEL Batterys will not cause environmental pollution; Solar GEL Batterys can be large and small simultaneously, large to one million kilowatts of medium-sized power plants, small to only one for the use of Solar GEL Batterys, which is unmatched by other power
