Abstract

Through holes are opened in the junction of positive and negative electrodes of each cell correspondingly in a powered shading blanket of a solar cell detector of an improved mobile dark box. A small drum with a convex lens at the top end is arranged on each through hole and a light focusing point is arranged in the electrode junction. A photoconduction circuit is arranged among the electrodes of all dark resistance high-power cells. Combined photosensitive probes with an illuminometer are arranged in the powered shading blanket, of which one probe faces to the dark box and the other faces to the external light field. Precise nine parameters are comprehensively calculated by a computer according to parameters of reflective light and focusing Illumination received by each cell and each parameter of the cell photocurrent in a light-conducting window detected by a detector. If the parameters are qualified, the light-conducting window is ordered to move down for cycle operation and collection. If the parameters are unqualified, the light-conducting window stops under the control of the computer. A stepping motor controls a single-hole shading board to cover the light-conducting window so that the active shading blanket is folded and deformed to cover a large part of convex lens and only a straight photoconduction circuit with single hole is left to examine the cell in the light-conducting window one by one, thereby determining the position of defective cell or circuit.

Description

Improved mobile dark box solar cell detector

One, affiliated technical field

The utility model relates to the local performance parameter of a kind of detection solar panel, be aggregated into entire cell slab integral performance parameter, discern and define the device of defective batteries sheet position, especially install in the shading blanket and focus on photoconductive device, make the photocurrent of battery sheet in the leaded light window, the dark resistance dissipated power loss of battery section drops to minimum state in the dark box of process.

Two, background technology

At present, known solar panel local detection instrument, because being in, moves in the dark box most of battery sheet of solar panel, the dark conductance of battery sheet is very little, and its dark resistance value reciprocal is very big, the photocurrent that array battery sheet produces in the leaded light window, through the very big battery section of each dark resistance value in the dark box, it is very big that it is lost in the dark resistance dissipated power, impacts for the quality of battery sheet, and work brings inconvenience slower with detection speed to detection computations.

Three, summary of the invention

In order to overcome existing solar panel local detection instrument, be in the very big problem of dark resistance dissipated power loss of battery sheet in the dark box, the improved mobile dark box solar cell that the utility model provides detects detector, the focusing photoconduction device of this detector, reduce the dark resistance power consumption of battery section in the dark box, bring convenience to testing, the data precision and the speed of measurement all improve.

The technical solution of the utility model is: the mobile dark box that leaded light window both sides shading blanket constituted around one week of sales counter panel, its shading blanket is combined integrated by power shading blanket and activity shading blanket.In the power shading blanket of leaded light window both sides, corresponding to each battery sheet of solar panel just, the negative electrode weld tabs intersection through hole that opens the light, little cylinder is installed directly over the light through hole of power shading blanket, convex lens are equipped with on its top, light focusing point position at the battery sheet just, negative electrode weld tabs intersection constitutes the photoconductive device of focusing, the light focus point is radiated at the charge carrier that produces on the battery sheet and accumulates in positive and negative electrode weld tabs intersection under the built in field effect, make between the very high electrode of dark resistance value and become photoconductive circuit, just move interior each the battery sheet of dark box, the intersection of negative electrode weld tabs is all installed and is focused on photoconductive device, its electrode weld tabs connects into photoconductive circuit, the photocurrent that array battery sheet produces in the leaded light window flows to nine big parameter testers through the photoconductive circuit of low resistance power consumption, and tester array battery sheet in computing machine provides the leaded light window produces nine parameters of photocurrent.

Also install in the leaded light window both sides power shading blanket several illuminometers towards opposite combination photosensitive probe, one of them photosensitive probe solar panel in the dark box, detect each battery sheet of cell panel and in dark box, accept refract light illumination, its another photosensitive probe light field outside the shading blanket, just detect interior each battery sheet of dark box, the focal spot illumination that negative electrode weld tabs intersection is accepted, the daylighting circuit of each photosensitive probe of same combination connects the slip shading strip groove brush on power shading blanket both sides respectively, brush rides over and is mixed with the circuit of connecting illuminometer on the multichannel section strip conductor, and illuminometer each battery sheet in computing machine provides dark box is accepted the illumination parameter of refract light illumination parameter and focal spot.

Preliminary nine parameters of photocurrent that computing machine provides array battery sheet in the leaded light window according to nine big parameter testers, provide in the dark box each battery sheet to accept the illumination parameter of refract light and the illumination parameter of focus point in conjunction with illuminometer, comprehensive together computing obtains accurate nine big parameters of array battery sheet photocurrent in the leaded light window.

It is combined integrated that activity shading blanket in leaded light window both sides is enclosed within power shading blanket outside, activity shading blanket is made reductus shape, corresponding to each opens the light hole towards the convex lens position that outer photosensitive probe and each focus on photoconductive device in the power shading blanket, activity shading blanket is by its gauffer distortion of step motor control, logical light hole displacement, gauffer hides convex lens and photosensitive probe, the gauffer of distortion hides most of convex lens, only stay together photoconductive circuit with single hole one straight line that covers the single aperture diaphragm on the leaded light window, array battery sheet in the leaded light window is satisfied an inspection and to this channel check, defined the position of defective batteries sheet position or fault.

The beneficial effects of the utility model are: install in the power shading blanket and focus on photoconductive device, the resistance power consumption of each battery sheet is reduced to and allows within the power consumption in the dark box, detection speed and detection data accuracy all further improve, activity shading blanket is more accurate to the understanding of defectiveness battery sheet and circuit, easier.
