title: The molecular engineering of organic sensitizers for solar-cell applications.
abstract: Positive to the core: ullazine has both strong electron-donating and weak accepting properties. This heterocycle was incorporated into sensitizers for dye-sensitized solar cells (DSCs). One of these sensitizers demonstrated strong light absorption across the UV/Vis region. The corresponding DSC device has a maximum IPCE of 95 % at 520 nm, with a power conversion efficiency of 8.4 %.
