Abstract
Solar cell modules are provided having a solar cell layer and a colored multi-layer encapsulant sheet where an uncolored surface sub-layer of the encapsulant sheet is in direct contact with the solar cell layer.
Claims21
A solar cell module comprising a laminate structure, the laminate structure comprising a solar cell layer and a colored multi-layer polymeric sheet, wherein
- (A) the solar cell layer is selected from the group consisting of solar cell layers comprising a single solar cell and solar cell layers comprising a plurality of electrically interconnected solar cells;
- (B) the solar cell layer has a light-receiving side and a non-light-receiving side;
- and
- (C) the colored multi-layer polymeric sheet comprises a first surface sub-layer that is positioned such that it is adjacent to and in direct contact with the solar cell layer, a second surface sub-layer positioned such that it does not contact the solar cell layer, and optionally at least one inner sub-layer positioned between the two surface sub-layers, wherein
- (i) the first surface sub-layer is uncolored and substantially free of electrically conductive color pigment;
- and
- (ii) at least one sub-layer, other than the first surface sub-layer, is colored and comprises at least one electrically conductive color pigment.

A process for preparing a solar cell module, comprising:
- (A) providing an assembly comprising, in order of position,
- (1) a solar cell layer,
- (2) a first polymeric sheet that is uncolored and substantially free of any electrically conductive color pigment, and
- (3) a second polymeric sheet that is colored and comprising at least one electrically conductive color pigment,
- wherein
- (i) the solar cell layer is selected from the group consisting of solar cell layers comprising a single solar cell and solar cell layers comprising a plurality of electrically interconnected solar cells;
- (ii) the solar cell layer has a light-receiving side and a non-light-receiving side;
- and
- (iii) the uncolored first polymeric sheet is in direct contact with the non-light-receiving side of the solar cell layer, and
- (B) laminating the assembly to form the solar cell module.
