Cold light can make solar panels generate electricity
(1) the method of light, heat and electricity is used to generate electricity by solar radiation, and the heat energy absorbed by the solar collector is converted into the steam of the working medium. A process before it is light - heat transfer process; after a process of heat - and eventually converted to electricity conversion process, as with an ordinary power. Solar thermal power generation is very low efficiency and high cost, estimated at least its investment than the average thermal power station cost 5 ~ 10 times.
(2) the direct conversion of light to electricity is the direct conversion of solar radiant energy into electric energy by photoelectric effect. The solar cell is a kind of the photovoltaic effect of solar energy will be directly converted into electrical energy device, a semiconductor photodiode, when the sun light to the photoelectric diode, photodiode will be the sun's energy into electricity, generate electricity. When many batteries are connected in series or in parallel, they can be used as a solar cell array with relatively large output power. Solar power is a new promising, with a permanent, clean and flexible. Three major advantages of solar battery life long, as long as the sun, the solar cell can be an investment in long-term use; compared with the thermal power generation, solar cells will not cause environmental pollution.
(1) the light - heat - electricity - electricity conversion mode uses the heat energy generated by the solar radiation to generate electricity, and the heat energy absorbed by the solar collector is converted into the steam of the working substance. A process before it is light - heat transfer process; after a process of heat - and eventually converted to electricity conversion process, as with an ordinary power. Solar thermal power generation is very low efficiency and high cost, estimated at least its investment than the average thermal power station cost 5 ~ 10 times.
Can generateThere are two ways of solar power generation, one is light - heat - electricity conversion, the other is the direct conversion of light and electricity.
