Ubiquitous Energy being absorbed. Developed from research done at Massachusetts Institute of Technology (MIT) they have developed organic photoactive materials (organic photovoltaics, OPVs) that allow visible light to pass through its technology but selectively absorb the light from the invisible part of the spectrum, near infrared (NIR) and ultraviolet (UV) light. They call this technology ClearView power. ClearView Power is an invisible film less than 1/1000 of a millimeter thick that can be put onto any surface and generate energy without with out affecting the material beneath it. Specifically they are trying to capture all of the photons of ultraviolet and infrared
Flashtube is undesired, whether due to production of ozone, damage to laser rods, degradation of plastics, or other detrimental effects. In these cases, a doped fused silica is used. Doping with titanium dioxide can provide different cutoff wavelengths on the ultraviolet side, but the material suffers from solarization; it is often used in medical and sun-ray lamps and some non-laser lamps. A better alternative is a cerium-doped quartz; it does not suffer from solarization and has higher efficiency, as part of the absorbed ultraviolet is reradiated as visible via fluorescence. Its cutoff is at about 380 nm. Conversely, when ultraviolet is
