While this technology is a world away from being commercialized, it’s nice to know that folks are still tinkering. I’m lost on the technology but excited by the prospect. For a copy of the full presentation, click-here.
Columbus (OH) – Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun’s visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be “siphoned off” as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial products are still years away, but this foundational work may well pave the way for a truly renewable form of clean, global energy.
