Problems solved by technology

In addition, due to such a failure in the transportation process, the positions of the cells constituting the battery string and the solar cell panel are also deviated from each other, and accurate defect inspection of the solar cell cells cannot be performed, which also brings obstacles to the lamination process in the subsequent process.

Embodiment 1

[0151] use Figure 11 and Figure 12 A first embodiment of the transport device of the solar cell inspection device of the above will be described. Figure 11 is the front view viewed from the conveying direction, Figure 12 is a side view. The conveyance part 221R / L is comprised from the chain 222, the upper chain guide 223, the lower chain guide 224, the conveyance guide 225, and the attachment 226 for conveyance guide attachment. A plurality of conveying guides are installed on the chain by attachments, and are connected in an endless manner by the chain. The above-mentioned chains are supported by upper chain guides and lower chain guides arranged along the conveying direction. One pair (two rows) of such transport units is provided symmetrically with respect to the transport direction. Such as Figure 11 As shown, the object 200 to be measured is placed on the conveyance guide 225 and conveyed.

[0152] As described above, the object to be measured is in a state w...

Embodiment 2

[0156] The second embodiment of the delivery device of the solar cell inspection device of the above , instead of Figure 11 and Figure 12 Multiple conveying guides set on the chain in, such as Figure 13 As shown, the conveyance guide uses an annular belt-shaped body 322 having the same cross-sectional shape as the conveyance guide 225 .

[0157] The transport unit 321R / L is constituted by an annular belt-shaped body 322 , an upper belt holder 323 , and a lower belt holder 324 . One pair (two rows) of such transport units is provided symmetrically with respect to the transport direction. Ribbon 322 as Figure 13 As shown, the object to be measured 200 is placed and transported.

[0158]The object to be measured transported in the same manner as in Example 1 was in a state where the transparent substrate, the solar cell, the filling material, and the back surface material were laminated before the lamination process. Therefore, the back material is larger than the transp...

Abstract

A solar cell examination apparatus for examining a solar cell by applying a current in the forward direction to the solar cell thereby to cause EL emission of the solar cell is disclosed. The examination apparatus has a simple structure and is produced at low cost. A transfer device for transferring a stack of constituent members of a solar cell to be measured before lamination thereof to the examination apparatus is also disclosed. The stack of the constituent members is prevented from being displaced. The solar cell examination apparatus includes a dark chamber (110) having an opening (or a transparent plate) (112) in the top surface, a support means which is provided on the top surface (111) of the dark chamber and on which an object to be measured is placed, and a camera (120) provided inside the dark chamber (110). The solar cell examination apparatus further includes a light-shielding cover for interrupting light entering the dark chamber through the opening and through the gap between the opening (112) and the solar cell placed on the support means. The transfer device includes a pair of lines of transfer members (two lines) connected in an endless form in the transfer direction. Each transfer member has a wall lower than the thickness of the stack of the constituent members such as a transparent substrate of the solar cell being transferred. The two lines of transfer members guide the stack of the constituent members to prevent the constituent members from being displaced during the transfer.

Description

technical field [0001] The present invention relates to a device for inspecting general performance of solar cells such as solar battery cells, battery strings in which solar battery cells are connected in a row, and solar battery panels in which a plurality of battery strings are arranged in parallel, and an inspection device used for the same delivery device. Background technique [0002] A silicon type solar cell is known as a method of utilizing solar energy. In the manufacture of solar cells, it is very important to evaluate whether the solar cells have the target power generation capability. In performance evaluation, measurement of output characteristics is usually performed. [0003] The output characteristics were performed as photoelectric conversion characteristics for measuring the current-voltage characteristics of the solar cell under light irradiation. Sunlight is preferable as the light source, but since the intensity of irradiation changes depending on th...
