Establishing nanoscopic structure-function relationships in the working electrodes of dye-sensitized solar cells
Dye-sensitized solar cells are a strong contender for next-generation photovoltaic technology with niche applications as solar-powered windows. The performance of a DSSC is particularly susceptible to the dye sensitizer, which is adsorbed onto the surface of a wide-band-gap semiconductor such as …

Fluorescence Enhancement Strategies for Polymer Semiconductors
… efficient energy transfer to a more emissive squaraine dye molecule is possible despite fast non-radiative decay short exciton diffusion lengths. This results in a significant fluorescence enhancement, which in turn facilitates an order of magnitude increase of the efficiency of polymer light …

Light Harvesting using Metal-Organic and Organic Sensitizers in Hybrid Solar Cells: Synthesis, Characterisation and Application
… the blue-green region arising from MLCT, these dyes feature much higher extinction coefficients in comparison to a commercially available reference dye lacking any donor-antenna groups. By the application of these Ru(II) complexes in solid-state dye-sensitized solar cells, we found a clear …

Synthesis, Linear and Nonlinear Photophysical Characterization of Two Symmetrical Pyrene-terminated Squaraine Derivatives in Solution
Two indole-based squaraine dyes bonded to two pyrenyl groups through vinyl- and ethynyl- linkers were synthesized with the aim of enhancing the intramolecular charge transfer interaction in addition to improving their optical properties. The absorption and emission properties of these derivatives …
