## Abstract

A photovoltaic cell module includes a photovoltaic cell panel whose planar shape is a rectangular shape; an insulating material adhered to the photovoltaic cell panel, so as to cover the photovoltaic cell panel from an outer peripheral part on a light receiving surface side, via a side end surface, to an outer peripheral part on a back surface side; and a frame member configured to protect a periphery of the photovoltaic cell panel to which the insulating material is adhered, wherein among a first side and a second side of the photovoltaic cell panel facing each other, at least on the first side, the insulating material, which is adhered to the light receiving surface and the side end surface of the photovoltaic cell panel, and the frame member can be spaced apart from each other.

## Claims

### Claim 1

A photovoltaic cell module comprising:
a photovoltaic cell panel whose planar shape is a rectangular shape;
an insulating material adhered to the photovoltaic cell panel, so as to cover the photovoltaic cell panel from an outer peripheral part on a light receiving surface side, via a side end surface, to an outer peripheral part on a back surface side;
a frame member configured to protect a periphery of the photovoltaic cell panel by a structure where the periphery of the photovoltaic cell panel is adhered to the insulating material and inserted into the frame member,
wherein among a first side and a second side of the photovoltaic cell panel facing each other, at least on the first side, the insulating material, which is adhered to the light receiving surface and the side end surface of the photovoltaic cell panel, is not adhered to the frame member so that the insulating material and the frame member can be spaced apart from each other,
the frame member includes a back surface flange configured to support the back surface side of the photovoltaic cell panel, and
on the first side where the insulating material and the frame member can be spaced apart from each other, the back surface flange and the back surface of the photovoltaic cell panel are directly adhered to each other by an adhesive material.

### Claim 2 (depends on 1)

The photovoltaic cell module according to claim 1, wherein
the photovoltaic cell panel includes a photovoltaic cell element, a front surface protective layer configured to protect the light receiving surface side of the photovoltaic cell element, and a back surface protective layer configured to protect the back surface side of the photovoltaic cell element,
the insulating material is adhered to the photovoltaic cell panel, so as to cover the photovoltaic cell panel from an outer peripheral part on a light receiving surface side of the front surface protective layer to an outer peripheral part on a back surface side of the back surface protective layer, and
the back surface protective layer is a glass substrate.

### Claim 3 (depends on 2)

The photovoltaic cell module according to claim 2, wherein a protecting sheet made of a polyethylene terephthalate resin is provided on the back surface of the back surface protective layer.

### Claim 4 (depends on 1)

The photovoltaic cell module according claim 1, wherein on the second side, which faces the first side where the insulating material and the frame member can be spaced apart from each other, the insulating material and the frame member are adhered to each other.

### Claim 5 (depends on 1)

The photovoltaic cell module according claim 1, wherein the insulating material includes an insulating tape.

### Claim 6 (depends on 1)
