Abstract
The present invention provides a protective backing sheet for photovoltaic modules. The backing sheets are capable of absorbing a wide range of solar wavelengths (UV, IR and visible) and re-emitting the absorbed solar radiation as a photons wherein the energy is at or greater than the band gap energy of corresponding semiconductor. The backing sheet can be used in a variety of applications including in photovoltaic devices.
Claims23
A backing sheet for a photovoltaic module comprising:
- a polymer layer comprising one or more white pigments and one or more photo luminescent materials.
A photovoltaic module comprising:
- a backing sheet comprising one or more white pigments and one or more photo luminescent material, wherein the backing sheet is capable of absorbing solar radiation and converting the absorbed solar radiation into a peak emission wavelength;
- and
- one or more semiconductors comprised of a material with a band gap at or near the peak emission wavelength.
A method of boosting the power of a photovoltaic module with a backing sheet comprising:
- applying a coating comprising one or more white pigments and one or more photo luminescent materials to a portion of the backing sheet facing the photovoltaic cells.
