Embodiment 1

[0021] like figure 1 As shown, the solar cell panel 50 for a vehicle includes a protective cover 41 , a rear surface cover 43 , a solar cell string 45 , and a sealing member 47 . The solar cell panel 50 for a vehicle is an example of the "solar cell panel" in the present invention. This vehicle solar cell panel 50 is used in a vehicle not shown, and is attached to a roof. In addition, the details of the protective cover 41 , the rear surface cover 43 , the solar cell strings 45 , and the sealing member 47 will be described later.

[0022] In this embodiment, the figure 1 The direction indicated as "front" in the middle is set to the front of the vehicle solar cell panel 50, and the figure 1 The direction indicated as "rear" in the middle is set to the rear of the solar cell panel 50 for a vehicle, and the front-rear direction of the solar cell panel for a vehicle 50 is defined. In addition, the figure 1 The direction indicated as “up” in the middle is set as the upper sid...

Embodiment 2

[0052] In the manufacturing method of Example 2, in the preparation step S1, the preparation Figure 8 Lamination device 101 is shown. In this lamination apparatus 101 , with respect to the support surface 310 of the lamination jig 3 , a stepped portion 310 a protruding toward the laminated body 40 is formed. In addition, the shape of the step portion 310a can be appropriately changed. Other structures in this manufacturing method, including other structures in the lamination apparatus 101, are the same as the manufacturing method of Example 1.

[0053] In this manufacturing method, in the crimping step S32, the rear cover 43 can be bent into a convex shape toward the protective cover 41, and the step 43c can be provided with respect to the bottom plate 43a of the rear cover 43 using the shape of the step portion 310a. In other words, in this manufacturing method, the product shape of the rear cover 43 is curved toward the protective cover 41 in a convex shape, and the step ...

Abstract

The present invention provides a method for manufacturing a solar cell panel. A method of manufacturing a solar cell panel includes the steps of: preparing a laminated body having: a protective cover made of resin having light transmission properties and bent into a convex shape; a flat rear surface cover made of resin; and a solar battery cell. and a sealing member that keeps the solar cell in a sealed state; placing the laminate on the lamination jig in such a manner that the rear surface cover is in contact with the lamination jig; and heating the laminate by the lamination jig, And the laminated body was clamped by the separator and the lamination jig, and the laminated body was crimped, and the solar cell panel was obtained from the laminated body. The lamination jig is bent into a convex shape towards the laminate.

Description

technical field [0001] The present invention relates to a method of manufacturing a solar cell panel. Background technique [0002] Japanese Patent Application Laid-Open No. 2010-149506 discloses a conventional manufacturing method of a solar cell panel (hereinafter, simply referred to as a conventional manufacturing method). The conventional manufacturing method includes a preparation process, a placement process, and a lamination process. In addition, in the conventional manufacturing method, a lamination apparatus having a separator, a lamination jig, and a heater is used. The diaphragm and the lamination jig are arranged to face each other. The heater can heat the lamination jig. [0003] In the conventional manufacturing method, first, a preparation process is performed. In a preparation process, the laminated body which has a protective cover, a back surface cover, a some solar cell, and a sealing material is prepared. The protective cover has light transmittance ...
