A multi-layer backsheet for a photovoltaic module comprising a first layer having a reflectance of more than 25% of a light with a wavelength anywhere from about 1000 nm to about 2100 nm, and a reflectance of less than 35% of all light with a wavelength from about 380 nm to about 750 nm; and a second layer having a reflectance of more than 50% of all light with a wavelength from about 380 nm to about 2000 nm. A photovoltaic module comprising the multi-layer backsheet, a method of making the photovoltaic module, and a method of converting sunlight into electricity by exposing the photovoltaic module to sun light.

Backsheets for photovoltaic modules using infrared reflective pigments

The present invention relates to phase change materials (PCMs) which may be used with photovoltaic (PV) modules. More specifically, solid/solid PCMs having a polyolefin backbone polymer and a crystallizable side chain are provided. Preferably, the solid/solid PCM has a copolymer backbone having a polyolefin repeating unit, and the crystallizable side chains are grafted onto the copolymer backbone. Most preferably, the copolymer is poly(ethylene-co-glycidyl methacrylate) (PE-co-GMA), and polyethylene glycol (PEG) is the crystallizable side chain. Photovoltaic modules and backsheets for photovoltaic modules having solid/solid PCMs are also provided.
