Body output measures fixture 1 and forms amperometric determination terminal 6 by arranging multiple probes 4, in addition, by arranging multiple probes 4
And form voltage determination terminal 7.
Moreover, solar battery cell is measured with output in fixture 1, the end of multiple probes 4 of amperometric determination terminal 6 is formed
Portion is connected each other by the solder connection of copper cable, and is connected with galvanometer 8.Solar battery cell measures folder with output
In tool 1, the end for forming multiple probes 4 of voltage determination terminal 7 is connected each other by the solder connection of copper cable, and with
Potentiometer 9 connects.
Each probe 4 have by pin main body 4a that stent 5 is kept and the front end for being located at pin main body 4a and with solar cell list
The abutting part 4b that the surface electrode 3 of body 2 abuts.Pin main body 4a is formed as cylindric, and abutting part 4b is formed as more straight than pin main body 4a
Footpath bigger it is cylindric.Probe 4 is kept by pin main body 4a by stent 5, so as to which abutting part 4b dashes forward from the lower surface 5b of stent 5
Go out, the end of pin main body 4a is protruded from the upper surface 5a of stent 5.Moreover, probe 4, passes through the upper surface 5a protrusions from stent 5
The end of pin main body 4a is bundled each other by solder connection of copper cable etc., so as to which multiple probes 4 form the long side throughout stent 5
Direction simultaneously arranges the amperometric determination terminal 6 formed and voltage determination terminal 7.
On the surface of the abutting part 4b of probe 4, slot is formed.
The stent 5 of probe 4 is kept to be formed as rectangular plate-like using resin material.Upper and lower surface 5a, 5b of stent 5, by
The short side of the width of set shape is arranged as with the comparable long side of length on one side of solar battery cell 2 and with probe 4
It forms.Moreover, stent 5, multiple probes 4 are embedded in forming the given alignment of amperometric determination terminal 6 and voltage determination terminal 7
Between lower surface 5a, 5b.
[[linear arrangement]]
As described in Fig. 8 and Fig. 9, amperometric determination terminal 6 and voltage determination terminal 7 are disposed side by side on mutually under stent 5
Surface 5b.In addition, amperometric determination terminal 6 and voltage determination terminal 7 together along stent 5 lower surface 5b long side direction straight line
It is formed shape.In each probe 4 for forming amperometric determination terminal 6 and voltage determination terminal 7, abutting part 4b forms diameter 3.5mm's
Cylindric, the interval S1 between adjacent abutting part 4b is shorter than the interval of general finger electrode, is 0.1mm.
Amperometric determination terminal 6, due to the interval S1 for the abutting part 4b that the surface electrode 3 with solar battery cell 2 abuts
For 0.1mm, for example only as surface electrode 3 and multiple finger electrode 3a parallel to each other formed with predetermined distance it is so-called
In solar battery cell 2 without bus bar configuration, can with than finger electrode 3a general interval (such as 1.0~
It is 2.0mm) short to be alternatively arranged abutting part 4b.Therefore, fixture 1 is measured according to solar battery cell output, even if due to too
It is positive can battery cell 2 and in the case of generating deviation at the interval of finger electrode 3a, also can be with whole finger electrode 3a's
Interval corresponds to.Even in addition, on the thickness of finger electrode 3a there are deviation in the case of, since probe 4 is in abutting part 4b
Surface there are multiple slots, the contact area of probe 4 and finger electrode 3a can also increased, reduces the inclined of measured resistance value
Difference, the output that can stablize measure.
In this way, solar battery cell measures fixture 1 with output, by forming amperometric determination terminal 6 and voltage determination end
Son 7 compared with the probe electrode of 1 row as the measure fixture of amperometric determination terminal and voltage determination terminal, can increase
With the quantity of the finger electrode 3a probes abutted, fixture 1 is measured in particular according to solar battery cell output, spy can be made
The abutting part 4b of pin 4 is abutted with whole finger electrode 3a.In addition, by forming amperometric determination terminal 6 and voltage determination end side by side
Son 7 is not capable of the width of upper and lower surface 5a, 5b of expanded stent 5, by the shielding caused by stent 5 in the measure of electrical characteristics
Loss inhibits relatively low, prevents output from declining.In addition, even if there are deviation on the thickness of finger electrode 3a, since probe 4 exists
The surface of abutting part 4b has multiple slots, can also increase the contact area of probe 4 and finger electrode 3a, reduces measured electricity
The deviation of resistance value, the output that can stablize measure.
In addition, as described in Figure 9, amperometric determination terminal 6 and voltage determination terminal 7, mutual probe 4 is one in orientation
It partly overlaps.That is, amperometric determination terminal 6 and voltage determination terminal 7, long side side of the mutual probe 4 along the lower surface 5b of stent 5
To being arranged in parallel, from the point of view of the width of the lower surface 5b of the stent 5 vertical with the orientation, with the probe 4 of one
The mode that is located between the probe 4 of another one of center of abutting part 4b arrange, and the interval between mutual abutting part 4b
S2, it is, for example, 0.1mm and close arrangement.
Amperometric determination terminal 6 and voltage determination terminal 7 as a result, since the abutting part 4b by mutual probe 4 is from arrangement
A part of overlapping from the point of view of direction, can on the width of the lower surface 5b of stent 5 narrowization and arrange.Therefore, stent 5
In, the width of the stent 5 abutted against with the surface of solar battery cell 2 becomes narrowization, can prevent from being led by shadow loss
The output of cause declines.
Solar battery cell measures fixture 1, such as the Current Voltage of the solar battery cell for 6 inches with output
In the case of the measure of characteristic, the long side of upper and lower surface 5a, 5b of stent 5 is the length with one side of solar battery cell 2
