Dye-Sensitized Solar Cell with Integrated Triplet–Triplet Annihilation Upconversion System
Photon
upconversion (UC) by triplet–triplet annihilation
(TTA-UC) is employed in order to enhance the response of solar cells
to sub-bandgap light. Here, we present the first report of an integrated
photovoltaic device, combining a dye-sensitized solar cell (DSC) and
TTA-UC system. The integrated device displays enhanced current under
sub-bandgap illumination, resulting in a figure of merit (FoM) under
low concentration (3 suns), which is competitive with the best values
recorded to date for nonintegrated systems. Thus, we demonstrate both
the compatibility of DSC and TTA-UC and a viable method for device
integration
