Description
Technical field
The utility model relates to a kind of device that quickens the crystal-silicon solar cell photo attenuation.The crystal-silicon solar cell of this apparatus processes is single crystal silicon solar cell or polycrystalline silicon solar cell.
Background technology
Crystal-silicon solar cell is the main product in present photovoltaic cell market.Yet, owing to introduced impurity in the silicon crystal growth course, cause adulterant wherein to form recombination centers to the initial stage illumination meeting of battery, thereby the minority carrier life time of silicon chip is reduced with impurity such as oxygen, iron, cause that battery conversion efficiency descends, the generation photo attenuation.
The general mode that battery is carried out open-air exposure that adopts is studied its light induced attenuation characteristic in the industry, but this mode receives extraneous weather effect easily.It is 1 kilowatt/m that the mechanism that also has uses light intensity
2Analog light source do light irradiation apparatus.This dual mode is all longer required experimental period, is approximately 10 to 20 hours.
The utility model content
The utility model technical matters to be solved is to provide a kind of device that quickens the crystal-silicon solar cell photo attenuation.This device adopts the light source of high light intensity that crystal-silicon solar cell is handled, and can under the prerequisite that does not influence other performances of crystal-silicon solar cell, quicken its decay.
A kind of device that quickens the crystal-silicon solar cell photo attenuation that the utility model relates to comprises the substrate that carries sample, it is characterized in that: this device also is provided with big air quantity fan and high light intensity light source; Said high light intensity light source is positioned at the top of substrate, illumination downwards; Said big air quantity fan, its wind direction is towards substrate.
To be high light intensity light source carry out illumination at the crystalline silicon solar cell modules or the front of adding a cover the battery sheet of ultra-clear glasses to this device, with big air quantity fan to its cooling so that it remains on normal working temperature.
Said high light intensity light source is xenon lamp or halogen tungsten lamp.With xenon lamp or halogen tungsten lamp battery is carried out illumination, the light source height can be regulated between 10cm to 40cm, and light intensity can be at 1 kilowatt/m
2To 3 kilowatts/m
2Between regulate.
Said fan is big air quantity axial flow blower.With big air quantity axial flow blower battery is lowered the temperature, air quantity can be at 0.5m
3/ min to 30m
3Regulate between/the min, the temperature of battery is between 60 ℃ to 70 ℃ when guaranteeing to test.
The principle that the utility model adopts intense light source illumination to quicken the crystal-silicon solar cell photo attenuation is:
Impurity such as oxygen, iron is the principal element that causes the crystal-silicon solar cell photo attenuation.When normal temperature illumination, energy goes out charge carrier greater than the photon excitation of the energy gap of silicon, and impurity such as adulterant and oxygen, iron generate the recombination center under the effect of charge carrier, cause photo attenuation.Increase the quantity of this part incident photon, can accelerate the generating rate in recombination center.Simultaneously, with big air quantity fan the battery cooling is caused other influences that battery temperature raises and brings to avoid strong illumination.
This device can expand according to the demand of experimental amount.
This device also can be used for the photo attenuation experiment of low multiple concentrator cell.
The utility model is simple in structure, and easy operating can shorten experimental period significantly.
