Abstract
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.
