First Claim
Patent Images
1. A protective sheet for a solar battery module, comprising:
- a weather-resistant sheet; and
a light confining layer formed on a surface of the weather-resistant sheet;
wherein;
the light confining layer has an irregular structure located on a side opposite from the weather resistant sheet;
the irregular structure comprises an arrangement of irregularities having a height or depth in a range of from 0.1 nm to 500 μ
m;
the light confining layer comprises a support film on a side having the irregular structure;
an air layer is disposed between the support film and the irregular structure;
an adhesive layer is disposed between the support film and the irregular structure, the irregular structure and the adhesive layer defining at least one cavity for the air layer to occupy; and
a gas-barrier layer is provided on the weather resistant sheet.

Abstract
A protective sheet for a solar battery module comprises a weather-resistant sheet (1) of, for example, a fluorocarbon resin, and a deposited inorganic oxide thin film (2) formed on one of the surfaces of the weather-resistant sheet (1). A surface-treated layer (3) is formed in the weather-resistant sheet (1) to enhance adhesion between the weather-resistant sheet (1) and the deposited inorganic oxide thin film (2).
