Description

A kind of jig for monomer IBC cell piece EL test

Technical field

The utility model relates to manufacture of solar cells technical fields, and in particular to a kind of pair of monomer IBC cell piece carries out The attachment device of EL test.

Background technique

EL tester full name is electroluminescent (English Electroluminescent) tester that shines, and is a kind of solar-electricity The Inner Defect Testing equipment of pond or battery component, using the electroluminescent principle of crystalline silicon, using high-resolution CCD camera The near-infrared image of picture shooting assembly obtains and determines the defect of component.The process that EL tester tests solar battery All be to be completed inside camera bellows, most direct test method be arrangement personnel inside camera bellows by EL tester and it is to be tested too The conducting wire of positive energy battery is connected.

Monomer IBC (Interdigitated back contact refers to and intersects back contacts) cell piece, refers to battery front side Electrodeless, positive and negative polarities metal grid lines are in finger-like cross arrangement in cell backside.The parallel two sides of conventional monomeric IBC cell piece are each There are 3 pads, welding side pad connects anode simultaneously or cathode carries out EL test.Single solar cell cannot directly be done Power supply uses.Several single battery series and parallels must be connected to as power supply and are tightly packaged into component.Photovoltaic module (is also named Solar panel) it is most important part in core and solar power system in solar power system.Its Effect is to convert solar energy into electrical energy, and be sent in battery and store, or push loaded work piece.

The decline of output electric energy, the heat that a certain piece of cell piece has the problems such as blackspot that will will have a direct impact on entire solar array The problems such as spot.Therefore it before component production, needs to carry out EL detection to monolithic IBC battery, it can for improving monolithic IBC cell piece By property, this is particularly significant to the entire solar array of raising.

In the prior art, it in test unit IBC battery, needs to handle each monomer IBC cell piece, in list It is welded on body IBC cell piece, extraction electrode, and does the insulation processing of an anti-short circuit, this method is when detecting monomer IBC battery Extensive work is increased, it is cumbersome.

In the prior art, EL detection is carried out to monolithic IBC cell piece, conventional is small-lot testing, sample testing, idol You carry out integrated testability.But existing automation equipment is expensive, is only suitable for large batch of test, is not directed to small-lot testing Jig.

In the prior art, in test unit IBC cell piece, EL tester and monomer IBC cell piece pass through " crocodile The extraction electrode of battery is connected by the mode of folder " clamping with test macro.Script monomer IBC cell piece is close to tempered glass Plate, between the two without gap, when " crocodile clip " clamps the extraction electrode of battery, general extraction electrode is all shorter, " crocodile clip " When clamping the shorter extraction electrode of battery, gives cell piece upward power, will cause percentage of batteries piece and leave armorplate glass, with EL Tester armorplate glass has gap.Cell piece is required not have angle phase with EL tester armorplate glass in EL test process To level, and when " crocodile clip " clamps short extraction electrode, gap between the two will have a direct impact on survey in EL examination instrument reflect it is single The near-infrared image of body IBC cell piece, to influence the judgement to battery tablet quality.

In the prior art, EL detection is carried out to conventional solar energy crystal-silicon battery slice, is equipped with probe guide, be not suitable for described Front is electrodeless, and the monomer IBC battery that positive and negative polarities metal grid lines are arranged in cell backside carries out EL detection.

In conclusion being badly in need of a kind of jig for monomer IBC cell piece IBC battery solves existing in the prior art ask Topic.
