Controlling organic semiconductor band gaps by electron-acceptor fluorination
(PHYSorg.com Chemistry)

Organic semiconductor materials have the potential to be used in innovative applications such as transparent and flexible devices, and their low cost makes them particularly attractive. The properties of organic semiconductor materials can be tuned by controlling their structure at the molecular level through parts of the structure known as electron-accepting units. A group of researchers centered at Osaka University has specifically tailored an electron-accepting unit that was then successfully used in an organic semiconductor applied in solar cell device that showed high photovoltaic performance. Their findings were published in NPG Asia Materials.
