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).
Claims7
A protective sheet for a solar battery module, comprising:
- a weather-resistant sheet;
- an ultraviolet intercepting layer formed on one of the surfaces of the weather-resistant sheet, comprising a coating resin film containing dispersed metal oxide particles having a mean particle size in the range of 1 to 1000 nm;
- and
- a primer layer comprising a polyisocyanate primer or a polyacryamine primer interposed between the weather-resistant sheet and the ultraviolet intercepting layer to enhance adhesion therebetween.
A solar battery module comprising:
- a photovoltaic layer provided with solar cells;
- a pair of filler layers, each layer made of a polyolefin resin, contiguous respectively with opposite surfaces of the photovoltaic layer provided with solar cells;
- and
- a pair of protective sheets contiguous respectively with the pair of filler layers;
- wherein, (1) at least one of the pair of protective sheets comprises a weather-resistant sheet, and an ultraviolet intercepting layer, an infrared intercepting layer, or a highly reflective layer formed on one of the surfaces of the weather-resistant sheet and (2) a primer layer comprising a polyisocyanate primer or a polyacrylamine primer is interposed between the weather-resistant sheet and the ultraviolet intercepting layer, the infrared intercepting layer, or the highly reflective layer to enhance adhesion therebetween.
