New donor–π–acceptor dyes functionalised with a bodipy or indolium acceptor are described, which have an excellent spectral response in the red region and generate record photocurrent in tandem dye-sensitized solar cells. Our cationic acceptor dye, CAD3, generated a cathodic photocurrent density of 8.2 mA cm−2, the highest reported for a NiO p-type solar cell to date.

Sensitized Solar Cells

Metal-free organic sensitizer consisting of donor, electron conducting, and anchoring anhydride groups was engineered at molecular level and synthesized. Dye sensitized solar cells based on conjugated naphthalene dye were fabricated using nanoporous electrode. Photoelectrodes with a 7 μm thick nanoporous layer and a 5 μm thick light-scattering layer were used to fabricate dye sensitized solar cells. DSSCs were fabricated in a FTO/nc-TiO2/organic dye/I-/I3-/Pt/FTO device geometry. Dye sensitized solar cell was characterized by current density-voltage (J-V) measurement. All current-voltage (I-V) measurements were done under 100 mW/cm2light intensity and AM 1.5 conditions. The photovoltaic data revealed a short circuit photocurrent density of 1.86 mA/cm2, an open circuit voltage of 430 mV, and a fill factor of 0.63, corresponding to an overall conversion efficiency of 0.53%.

Indoline dyeD-1was successfully applied as a cosensitizer for improving the spectral response of black dye in dye-sensitized solar cells (DSCs). It was observed thatD-1effectively increases the short-circuit photocurrent by offsetting the competitive light absorption byI/I3-electrolyte in the wavelength region 350–500 nm when adsorbed on the TiO2nanocrystaline films in a mix dye system. The DSCs containing theD-1and black dye achieved a power conversion efficiency of 9.80% with higher short-circuit photocurrent of 19.54 mA/cm2compared to the system of black dye without cosensitization under standard AM 1.5 sunlight.
