Example Embodiment

[0152] (Example 1)

[0153] On the contact surface of the probe whose tip is circular (diameter 1.5 mm), the average interval (average pitch) between adjacent circles among the concentric circles with an angle of 60°, an average depth of 45 μm, and an average depth of 45 μm is formed concentrically by cutting. ) is a 60μm groove ( Figure 17A as well as Figure 17B ).

[0154] like Figure 18 As shown, probes with grooves formed thereon are staggered and arranged in a region of the cell 1 with a side length of 156, arranged in two rows, and fixed by being embedded in a resin material (holder). The root portions (socket portions) of the probes arranged in this way were welded to copper wires and bundled for each row, thereby producing an output measurement jig for a solar cell.

[0155] One side of the bundle is a current measurement terminal, and the other side is a voltage measurement terminal. These terminals are used by connecting them to a solar simulator.

Example Embodiment

[0156] (Example 2)

[0157] In Example 1, except that the average interval (average pitch) of adjacent circles among the concentric circles of the grooves of the probe 4 was changed to 120 μm, the same procedure as in Example 1 was carried out to produce a solar cell output measuring jig. .

[0158] In addition, the average depth of the grooves became 95 μm.

Example Embodiment

[0159] (Example 3)

[0160] In Example 1, except that the average interval (average pitch) of adjacent circles among the concentric circles of the grooves of the probe 4 was changed to 250 μm, the same procedure as in Example 1 was carried out to produce a solar cell output measuring jig. .

[0161] In addition, the average depth of the grooves became 210 μm.

Abstract

A solar cell output measurement tool having a current measurement terminal that is formed through the arrangement of a plurality of probe pins and is for measuring a current characteristic of a solar cell, a voltage measurement terminal that is formed through the arrangement of a plurality of probe pins and is for measuring a voltage characteristic of a solar cell, and a holder for holding the current measurement terminal and voltage measurement terminal in parallel, wherein on each of the plurality of probe pins of the current measurement terminal and voltage measurement terminal, the surface of a contact part that comes into contact with a finger electrode of the solar cell has a plurality of grooves.

Description

technical field [0001] The present invention relates to an output measurement jig for a solar battery cell and an output measurement method for a solar battery cell. Background technique [0002] Conventionally, as a measurement jig for measuring electrical characteristics of a solar cell, a measurement jig having a plurality of probes in contact with bus bar electrodes of a solar cell is generally used (for example, see Patent Documents 1 and 2). [0003] In recent years, in order to reduce the number of man-hours for manufacturing solar cells and at the same time reduce the amount of electrode materials such as Ag paste used to reduce manufacturing costs, it has been proposed not to provide bus bar electrodes, but to use conductive bonding It is a process method in which the film and the finger electrode are directly connected to the solder ribbon as the internal wiring. Even in solar cells having such a structure without bus bars, the current collection efficiency is equ...
