no. 1 approach

[0038] refer to figure 1 , figure 2 , the solar cell panel inspection device according to the first embodiment of the present invention will be described. The solar cell panel inspection device is used to inspect the insulation performance of the outer peripheral insulating region 21 of the solar cell panel 100. The solar cell panel 100 includes a transparent insulating substrate 2 having a main surface 2u and sequentially laminated on the main surface 2u of the transparent insulating substrate 2. The transparent electrode layer 3, the semiconductor photoelectric conversion layer 4, and the back electrode layer 5 have a peripheral insulating region 21 exposing the main surface 2u of the transparent insulating substrate 2 near the outer periphery of the transparent insulating substrate 2. The solar cell panel inspection device has: a first terminal 31 for abutting against the back electrode layer 5; a second terminal 32 for abutting against the vicinity of the outer peripher...

[0058] refer to Figure 16 , Figure 17 , a solar cell panel inspection device according to a third embodiment of the present invention will be described.

[0059] The solar cell panel inspection device of this embodiment is basically the same as the device described in the first embodiment except that Figure 16 , Figure 17 As shown, there is a third terminal switching mechanism 38, which is used to control the one or more terminals while maintaining the state that the first terminal 31 is in contact with the back electrode layer 5 and the second terminal 32 is in contact with the transparent insulating substrate 2. All or part of the third terminal is switched between a first state in contact with the outer peripheral insulating region 21 and a second state in which it does not contact the outer peripheral insulating region 21 , Figure 16 represents the first state, Figure 17 Indicates the second state. The third terminal switching mechanism 38 can be a one-way switc...

Abstract

The invention provides a solar panel inspection device, a solar panel inspection method and a solar panel manufacturing method. The solar panel inspection device is a device used to inspect the insulation performance of the outer peripheral insulation area (21) of the solar panel (100). The solar panel includes a transparent insulating substrate (2) with a main surface (2u) and a stacked The transparent electrode layer (3), the semiconductor photoelectric conversion layer (4) and the back electrode layer (5), and has an outer peripheral insulating area (21) exposing the main surface (2u); the solar panel inspection device has a function for communicating with the back surface The first terminal (31) for contacting the electrode layer (5), the second terminal (32) for contacting near the outer peripheral end of the outer peripheral insulating region (21), and the second terminal (32) for connecting the first terminal (31) and the second terminal (31). One or more third terminals (33, 33a, 33b, 33c) between the terminals (32) and in contact with the outer peripheral insulating area (21) are used to apply a voltage between two terminals selected from these terminals. A voltage application unit (34) and a current detection unit (35) that detects a current flowing between the two terminals to which a voltage is applied.
