Unit are solar radiant energy utilization rate of the present invention can reach 71%.The solar radiant energy intensity that arrives earth surface is about 1.1～1.2kw/m
2Near (the noon in the summer tropic of cancer; Have only winter half the); The conversion efficiency of conventional photovoltaic module generating is about 16%; That is to say: every square metre conventional photovoltaic module generating can only have 0.160 kilowatt; Where has remaining energy all gone? Can find out from spectrum analysis: " electromagnetic wave that sunshine comprises be a very wide spectral region (0.25～2.5 μ m) promptly from infrared ray through versicolor visible light up to ultraviolet ray, be divided into substantially that ultraviolet light accounts for 7%, visible light account for 45% and infrared light account for about 47%." the spectrum sensitive maximum of crystal silicon solar energy battery do not overlap with the value of solar radiation fully, can utilize the model of solar cell operating characteristic to make an explanation.In order in silicon, to produce electron-hole pair, it is necessary that light has a definite minimum energy value.The energy of light increases along with the minimizing of wavelength, and promptly the energy of blue light is greater than ruddiness.For silion cell, form electric current in order to produce electron-hole pair, wavelength is less than the light of 1.1 μ m, and just near infrared ray and the visible light near visible light just has enough energy.The solar spectrum medium wavelength can not produce electron-hole pair greater than the wavelength part of 1.1 μ m, but changes heat into.Such light of nearly 25% can not produce electric energy and produce heat energy in the solar radiation.
Energy like light is enough to produce electron-hole pair, and the size of luminous energy is just inoperative so at this moment, and promptly no matter be ruddiness or blue light, a light quantum only produces an electron-hole pair on the luminous energy critical value, and energy remaining is converted into heat again.So 30% of solar energy part is converted into heat energy.
To the photoelectric transformation efficiency impact analysis, temperature raises, decrease in efficiency from temperature.1 ℃ of the every increase of temperature, open-circuit voltage V
OcThe descend 0.002/0.55 ≈ 0.4% of its house temperature, efficiency eta also thereby reduce same approximately percentage.
The solar energy that receives on the conventional in sum photovoltaic generation unit are has 16% the electric energy that converts to; Convert heat energy to more than 55% in addition; That is to say every square metre 0.16 kilowatt of conventional photovoltaic module generated output, producing heat energy power is more than 0.55 kilowatt.
If water is as heat accumulation ability medium, 1 square metre conventional polysilicon (or monocrystalline silicon) photovoltaic module can be elevated to 60 ℃ from 20 ℃ with 47.4 kilograms water every day.Sunshine-duration every day was calculated 0.55 kilowatt of 1 square metre power, specific heat of water 1 card/gram degree, 1 Ka Er=4.18 Jiao by 4 hours.
