## Description

- description: The photovoltaic performance of molybdenum cluster-sensitized solar
    cells has been explored with the challenge of enhancing their efficiency due to
    the low charge transfer efficiency. Aromatic sulfonate ligands (NS = naphthalene
    2,6-disulfonate = –OSO2–C10H6–SO3–) were now used for the functionalization of
    the {Mo6Ii8} cluster cores. The new functional [Mo6I8iI3a(H2O)2a(NS)a] cluster
    unit exhibits enhanced photophysical and photoelectrochemical properties compared
    to other homologues based on the {Mo6I8i} cluster cores. In greater detail, the
    role of the NS functional groups was beneficially emphasized for the improved
    oxidation stability of the cluster in a redox mediator, adjusting the emission
    lifetime to a suitable range for fast electron injection, and accelerating the
    charge transport process. The best as-synthesized Mo6 cluster-based solar cell
    resulted in a stable photocurrent of 2.38 mA cm–2 with a fill factor of 0.63 and
    the power conversion efficiency of 0.97% under an AM 1.5 illumination, a two times’
    enhancement in comparison to the reference iodide Mo6 cluster-based cell (0.52%).
    Specific attention focused on the increase of the power conversion efficiency
    up to 1.18% after 330 s and then reached the saturation trend. The enhanced charge
    transfer of the metal cluster complex was obtained from facile modifications of
    the functional apical ligands that result in advantageous photophysical and electrochemical
    characteristics, specializing in optoelectronic devices. This study provides the
    general methodology and knowledge for the next improvement of the photovoltaic
    efficiency of the Mo6 cluster-based sensitized solar cells.
