Street lamp solar street light

The sun light in semiconductor p - N junction, form a new company hole - solar street lamps Electron pair in p - N junction under the action of electric field, the hole from p to n area, electronic consists of n to p area, processing circuit to form a current. This is the photoelectric effect of solar cells for



the sun light in semiconductor p - N junction, form a new company hole - solar street lamps Electron pair in p - N junction under the action of electric field, the hole from p to n area, electronic consists of n to p area, processing circuit to form a current. This is solar battery operation principle of the photoelectric effect.

solar panel method of generating solar power has two kinds of methods, one is light - Hot - Electricity transformation method, the other is light - Electricity conversion method directly.

( 1) Light - Hot - Electricity conversion methods through the use of solar radiation of heat power generation, generally the heat energy is absorbed by the solar collector will be converted into working medium vapor, to drive a turbine to generate electricity. A process is light - before Thermal conversion process; After a process is a hot - Electricity conversion process.

( 2) Light - Electric direct conversion approach is the use of photoelectric effect, the solar radiant energy directly into electricity, light - Electricity transformation of basic unit is the solar cell. The solar cell is a kind of by Yu Guangsheng v effect and convert sunlight directly into electricity equipment, is a semiconductor photodiode, when the sun light to the photodiode, photoelectric diode can turn the sun's light energy into electrical energy, electric current. When many cells in series or parallel up can become a larger output power of the solar cell phalanx.
