we all know that now the street light energy is solar energy, thereby saving electricity, how then its photoelectric conversion, beneath the street lamp manufacturers to introduce the street light photoelectric conversion: street light photoelectric conversion principle is this: when the sun light in semiconductor p - Form a new hole - n junction Electron pair in p - N junction under the action of electric field, the hole by n to p areas, electronic from p to n area, processing circuit to form current, light - Hot - Electricity conversion by using thermal, produced by the solar radiation is generally the heat energy absorbed by the solar collector will be converted into working medium vapor, to drive a turbine power generation, light - Electricity direct conversion way the way is to use the photoelectric effect, convert solar radiation directly into electricity, light - Basic unit of electricity conversion is solar battery, solar cell is a kind of effect by Yu Guangsheng volts and convert sunlight directly into electrical energy device, is a semiconductor photodiode, when the sun light to the photodiode, photodiode can turn the sun's light energy into electrical energy, an electrical current. Conversion principle of it is actually very simple, want to know its principle and you won't feel confused, believe street lamp will be more popular in the future, for the street light photoelectric conversion we learned this. , LED street lamp
