Abstract
The invention relates to a light inspection wire connector of a solar cell laminated piece, which comprises a base, a positive pole, four metal conduction sheets, three diodes and a negative pole, wherein the three diodes are connected in series between the positive pole and the negative pole, and the four metal conduction sheets are respectively connected at both ends of the three diodes. By observing the shape and the distribution of I-V curves produced by light inspection equipment, a user can quickly judge whether the inspected solar cell lamination contains low-efficiency cell slices and can also confirm the probable positions of the low-efficiency cell slices, thereby narrowing the examining range for the subsequent examination of small low-efficiency cell slices.
Description
Technical field:
The present invention relates to the testing tool of solar photovoltaic assembly, relate in particular to the auxiliary detection instrument of inefficient battery sheet in the solar photovoltaic assembly production run.
Background technology:
The seldom single use of solar battery sheet, but the battery sheet that will have a similar characteristic is packaged into assembly after being connected in series, and forms basic group of body unit of solar battery array.Battery generally is connected on together to obtain desired voltage.In the ideal case, the battery sheet in solar module should show identical characteristic, and the I-V curve of whole assembly and single battery sheet should have similar shapes, just the yardstick of coordinate axis difference to some extent.
In actual conditions, all battery sheets all have different characteristics, total the minimum battery sheet of output has limited the output of whole assembly, be exactly the difference off resonance loss between the output of the maximum of summation that the maximum of all battery sheets is exported in the assembly and the actual arrival of assembly.The off resonance battery sheet that is present in the assembly can cause some battery sheet in produce power, and some battery sheet is at consumed energy, the worst situation is, when assembly or component string during by short circuit, the output of all " good " battery sheets all can consume on " bad " battery sheet, the consumption of energy on " bad " battery sheet causes the partial breakdown of battery P-N knot, can produce very big energy consumption in very little zone, caused local overheating, perhaps become " focus ", thereby cause battery component or destructive result such as glass cracking, solder fusing.
At present, in the production run of solar module, all be to adopt light inspection equipment that series connected battery sheet laminate is carried out the light inspection, positive and negative electrode after the series connection of battery sheet is inserted on the electrode of light inspection equipment, with the flicker analog light source battery laminate is carried out illumination, make battery laminate produce electric current,, judge the quality of tested battery laminate according to measured I-V curve by its I-V curve of light inspection testing of equipment.Yet, in the serial connection battery sheet in the monoblock battery laminate, only have certain part of a slice or a slice abnormal conditions to occur and be difficult to be detected, more really its residing Position Approximate.
In order to improve the accuracy of detection of existing lamination part of solar cell light inspection equipment, judge more accurately and whether contain the low battery power sheet in the lamination part of solar cell, the applicant after research and testing, successfully developed a kind of lamination part of solar cell light inspection electric wire connecting junction, it can address the above problem preferably.
Summary of the invention:
The purpose of this invention is to provide a kind of lamination part of solar cell light inspection electric wire connecting junction, it can utilize existing lamination part of solar cell light inspection equipment to judge whether contain lower powered battery sheet in the lamination part of solar cell more accurately.
The technical solution adopted in the present invention is:
Described lamination part of solar cell light inspection electric wire connecting junction, it is characterized in that: comprise base, positive terminal, four metallic conduction sheets, three diodes and negative terminal, three diodes are connected between positive terminal and the negative terminal, and four metallic conduction sheets are connected on the two ends of three diodes respectively.
Further, the metallic conduction sheet is fixed on the base with insulating rotationally.
Concrete using method of the present invention is as follows:
Positive terminal, negative terminal are inserted in the lamination part of solar cell light inspection equipment, make four metallic conduction sheets respectively with battery laminate in the electrode welding overlap, normal control light inspection equipment detects, observe the I-V curve map and can judge whether contain the low battery power sheet in the entire cell laminate fast, utilize the short circuit effect of diode to find a string battery that contains inefficient battery sheet, it is step-like that the I-V curve that tests out is presented, and can detect whether contain inefficient battery sheet in the circuit rapidly.
Owing between lamination part of solar cell and light inspection equipment, set up electric wire connecting junction, in this electric wire connecting junction, be provided with diode, every diode control two row's battery sheets, six row's battery sheets are divided into three groups, and per two rows draw and connect a diode, and three diode series connections are between the both positive and negative polarity of battery laminate, under normal circumstances, each diode is in reverse bias, and each battery can both normally produce electric energy, and the I-V curve of entire cell laminate is very normal.As first row and second row, when having the low battery power sheet among the 3rd row and the 4th row or the 5th row and the 6th row, because the resistance of the resistance of low battery power sheet can be higher unusually, other cell row groups can be impelled the respective diode reverse bias, cause diode current flow, the electric current that originally flows through lower powered battery sheet is shunted by diode, and it is step-like to cause the I-V curve to present.By observing light inspection I-V curve shape and distribution thereof that equipment produced, just can judge whether contain inefficient battery sheet in the tested lamination part of solar cell rapidly, can also determine which two row's battery sheet the low battery power sheet is arranged in, for the accurate investigation of follow-up low battery power sheet has been dwindled the investigation scope.
Description of drawings:
Fig. 1 is the existing connecting circuit synoptic diagram that inefficient battery sheet detects;
Fig. 2 is the connecting circuit synoptic diagram that inefficient battery sheet of the present invention detects;
Fig. 3 is a structural representation of the present invention.
Among the figure: the 1-base; The 2-positive terminal; 3-metallic conduction sheet; The 4-diode; The 5-negative terminal; 6-electrode welding.
Embodiment:
The lamination part of solar cell that is connected in series with six row's battery sheets is an example below, accompanying drawings the specific embodiment of the present invention:
Described lamination part of solar cell light inspection electric wire connecting junction, it comprises base 1, positive terminal 2, four metallic conduction sheets 3, three diodes 4 and negative terminals 5, three diodes 4 are connected between positive terminal 2 and the negative terminal 5, four metallic conduction sheets 3 are connected on the two ends of three diodes 4 respectively, and metallic conduction sheet 3 is fixed on the base 1 rotationally with insulating.
Concrete using method of the present invention is as follows:
According to the characteristic of diode as can be known, as can be seen from Figure 2, when circuit just often, there is not electric current in the diode 4, when having inefficient battery sheet, diode 4 conductings, test its I-V curve, step-like I-V curve must occur, then illustrate to have inefficient battery sheet in the circuit.
