Solar modules containing a single-layer polyolefin-based backsheet

摘要

A solar module (1) comprising in order of position from the front, i.e. the light-receiving side, to the back:
(a) a top part (40) comprising a top layer (11) and a solar cell layer (12) and
(b) a bottom part (41) comprising a single-layer backsheet (13) having a top surface (131) and opposite thereto a rear surface (111) that is exposed to the outside of the solar module (1) and wherein the single-layer backsheet (13) comprises a polyolefin layer (114) containing as its major component a cross-linked polymer selected from polyethene homo polymers, polypropene homopolymers, polyethene copolymers comprising repeating units derived from ethene and one or more ±-olefinic hydrocarbons, polypropene copolymers comprising repeating units derived from propene and one or more ±-olefinic hydrocarbons and combinations thereof. Also provided are methods for making a solar module using the single-layer backsheets and methods for mounting a solar module on an aluminium containing support structure and support structures containing the solar module.
