- Solar cells, dye-sensitized;
A new coumarin dye (see figure) for use in dye-sensitized solar cells (DSSCs) is reported. It exhibits near-unity light harvesting efficiency and incident photon-to-electron conversion efficiency (see figure) over a wide spectral region in 6 μm transparent TiO2 films. DSSCs based on this metal-free organic dye show long-term stability and power-conversion efficiencies of around 6 % under continuous light-soaking stress for up to 1000 h.
