Sunovia Energy Technologies Inc. and EPIR Technologies Inc. say they have successfully demonstrated optical down-conversion for increased solar cell energy efficiency.

Optical down-conversion enhances solar cell efficiency by converting the sun's ultraviolet light into visible light, which can be used more effectively by the solar cell. With optical down-conversion, much of the energy from UV light can be converted into electricity, making solar systems more efficient.

The companies have demonstrated down-conversion in glass ceramic materials containing nanoparticles. These nanoparticles contain a rare earth ion that makes them transparent to visible light, creating an ideal top layer for solar cells. The ceramic glass material also safeguards efficiency by minimizing energy loss due to heat.

Sunovia and EPIR say their down-conversion technology is compatible with nearly all types of rigid solar cells on the market today.
