Description
Technical field
The application belongs to photovoltaic art, particularly relates to a kind of photovoltaic cell concentrating testing apparatus.
Background technology
In recent years, solar cell, as a kind of novel regenerative resource, more and more receives the concern of people, and its status on energy industry is also more and more important.Constantly deeply the probing into for high performance solar batteries along with the development of heliotechnics and people, tie by multiple PN the main flow that concentrating solar battery system that the high performance solar batteries that forms and concentrating component form jointly is bound to become solar cell application.
For the solar cell that multiple PN ties, in actual application, not often that on-line operation is out of doors under sunlight, but by collector lens, a large-area sunlight to be converged to the battery surface of a piece very little, this solar cell surface unit are is made to have received higher than common sunlight several times even light intensity of hundred times (specifically depending on the ratio of lens area and lens focus facula area size) like this, one piece of onesize solar cell is so just made to produce higher output current (output current can be directly proportional to light concentrating times) and output voltage, therefore the power output of solar cell can significantly be improved.
But under different intensities of illumination and different temperature, the electric current-voltage characteristic of solar cell also can change.Therefore, inspection battery of good performance under the condition of 1 standard sunlight (outdoor daylight) is needed whether under high power concentrator condition, to still have excellent current-voltage characteristic, and wish can find out this battery can export the highest power output under how many light concentrating times, has the highest energy conversion efficiency etc. under how many light concentrating times.Solar cell optically focused test macro is exactly a kind ofly can carry out current/voltage performance test to solar cell under higher than common sunlight light intensity several times or the condition of hundreds of times and effective record test data (open circuit voltage, short circuit current, fill factor, curve factor, efficiency, series resistance, parallel resistance etc.) and i-v curve complete set system.
In current solar cell optically focused field tests, be all often by adding collector lens or directly replacing the method for traditional xenon source to realize optically focused test with the light source of high light intensity.But due to existence and the loss of light in route of transmission of scattered light, light concentrating times is not proportional linearly to the distance of battery surface with collector lens, therefore often accurately, quantitatively can not calibrate light concentrating times.In other words, when light intensity is certain, the optically focused test macro of existing employing Fresnel Lenses all merely can only be increased by the position changing Fresnel Lenses or is reduced light concentrating times, and tester can not know the light concentrating times of the hot spot being irradiated to battery surface exactly.
In addition, adopt condensation light source to realize the system of optically focused test, namely standard sources is directly replaced by the condensation light source with certain light concentrating times, directly battery is tested, do not need to add any collector lens.Although single light concentrating times can be determined quantitatively like this, however tested hot spot light concentrating times can not to adjust be the large shortcoming of one, and condensation light source involves great expense, and is difficult to extensive use.
