Background technology
Photovoltaic market development at present is rapid, and the crystalline silicon solar cell modules demand is day by day soaring, and battery and component technology are constantly reformed, and have developed the battery of two-sided generating on the market, so the crystal-silicon solar cell double-side assembly also arises at the historic moment.Crystal-silicon solar cell double-side assembly technology roughly has two kinds; A kind of is that the encapsulation of assembly ultrawhite tempered glass is all used on the two sides; Another kind of system is positive to be encapsulated with transparent back panel with glass back, and technology is day by day ripe, progressively introduces to the market; Yet power test still is a difficult problem; Existing common component IV test board also is single face measured power (being single face assembly IV test board) basically, need test separately at the positive back side for the crystalline silicon solar cell modules of two sides generating, does not so also meet the demand of assembly actual power.
The utility model content
The utility model problem to be solved is to be to provide a kind of crystal-silicon solar cell double-side assembly electric performance test device.This device uses the electrical property of analog light source and existing single face assembly IV test board combined test crystal-silicon solar cell double-side assembly; This device is simple to operate; With low cost; Can remedy the deficiency of traditional components test board single face test, also can save the expense of buying expensive double-side assembly special test platform simultaneously.
A kind of crystal-silicon solar cell double-side assembly electric performance test device that the utility model relates to comprises single face assembly IV test board, and it is characterized in that: above single face assembly IV test board, be provided with light source bracket, light source bracket is provided with analog light source.Said analog light source is xenon lamp or halogen tungsten lamp.
Regulate analog light source is demarcated analog light source apart from the distance of assembly light intensity according to the short-circuit current of crystalline silicon solar cell modules; With the analog light source illumination module back side, obtain the IV curve and the associated electrical performance parameter of crystalline silicon solar cell modules according to the height of demarcating simultaneously with single face assembly IV test board test crystalline silicon solar cell modules front.
The course of work of the utility model:
1, positive with single face assembly IV test board test crystal-silicon solar cell double-side assembly, obtain the short-circuit current that the back side does not receive the light time assembly.
2, with analog light source irradiation crystal-silicon solar cell double-side assembly positive (back side does not receive light); When regulating light source and being above-mentioned steps 1 described current value apart from height to its short-circuit current of crystal-silicon solar cell double-side assembly; The light intensity of analog light source is the light intensity under the normal conditions here, i.e. a standard sun.
3, the crystal-silicon solar cell double-side assembly is placed on the single face assembly IV test board table top, face down the back side upwards, crystal-silicon solar cell double-side assembly both positive and negative polarity correctly links to each other with test board both positive and negative polarity connecting line.
4, shine the crystal-silicon solar cell double-side assembly back side according to the height of demarcating with analog light source, the positive general power that obtains its double-side assembly of test crystal-silicon solar cell double-side assembly obtains its IV curve and associated electrical performance parameter.
The said crystal-silicon solar cell double-side assembly of the utility model (is claimed again: the two-sided battery of the crystalline silicon sun); Its positive back side is with the encapsulation of common component ultrawhite tempered glass, or the front waits other two sides can receive the packaged type of light with glass back with the transparent back panel encapsulation.
The principle that the utility model adopts short-circuit current to demarcate analog light source is that the short-circuit current of assembly is directly proportional with the analog light source light intensity.
The utility model also can be tested the back side and receive light less than the situation of a standard solar time, like the standard sun of 20%, 40% equimultiple.
The utility model also can be used for testing other types solar cell double-side assembly.
The utility model is simple in structure, with low cost, practicality simple to operate.
