## Abstract

A method of producing a solar cell module including forming a silicon oxide layer by coating a paint containing at least one of silicate hydrolysis products and silica particles on at least one side of a base film; and adhering said silicon oxide layer with a silicone sealing material layer.

## Claims

### Claim at position 1

-7. (canceled)

### Claim 8

A method of producing a solar cell module comprising:
forming a silicon oxide layer by coating a paint containing at least one of silicate hydrolysis products and silica particles on at least one side of a base film; and
adhering said silicon oxide layer with a silicone sealing material layer.

### Claim 9 (depends on 8)

The method according to claim 8, wherein said silicate is butyl silicate.

### Claim 10 (depends on 8)

The method according to claim 8, wherein said base film contains an inorganic pigment.

### Claim 11 (depends on 8)

The method according to claim 8, wherein said base film comprises an ultraviolet absorbent-containing resin layer on the opposite side of the surface on which said silicon oxide layer is formed.

### Claim 12 (depends on 8)

The method according to claim 8, wherein said base film comprises an ultraviolet absorbent-containing resin layer and the surface on which said silicon oxide layer is formed is on the side of said resin layer.

### Claim 13

A solar cell backside sealing sheet comprising a silicon oxide layer formed by coating a paint containing at least one of silicate hydrolysis products and silica particles on at least one side of a base film.

### Claim 14 (depends on 13)
