New Solar Cell Material Captures Broad Sunlight Spectrum
Ohio State researchers have synthesized a new solar cell material that is capable of capturing solar energy over the whole spectrum of visible light. The material excites the electrons off the atoms in two states, dubbed singlet and triplet. The great news here is that the electrons in the triplet state are free from their atom for significantly longer, allowing the cell to marshall them into the array train. This could result in significantly higher efficiency ratios.
