A Japanese research team claims to have tailored an electron-accepting unit, which has been successfully used in an organic semiconductor applied in a solar cell device that showed high PV performance.A group of researchers from Japan's Osaka University has developed new fluorinated electron-accepting units that are said to be able to show precise control of the energy levels within the resulting semiconductor, which means these units are able to tune the band gap. This ability, they said, enables the selectivity over the injection and transport of holes and/or electrons within the semiconductor ...Den vollständigen Artikel lesen ...
