Cooperation of multifunction composite structures and fluorescein for photovoltaic performance-enhanced ZnO-based dye-sensitized solar cells

An NP/NSHS/NR hybrid structure was fabricated and used as a photoanode in dye-sensitized solar cells (DSSCs). The photoanode was treated in fluorescein acetonitrile solution (down-conversion materials) to enhance the photovoltaic efficiency, as well as in ascorbic acid ethanol solution to inhibit fluorescence quenching.523
