Dyes play a crucial role in the cell performance of dye-sensitized solar cells (DSSCs), and versatile synthetic strategies towards well-tailored porphyrins for DSSCs have been developed achieving high photovoltaic performances.

Among the new photovoltaic technologies, the Dye-Sensitized Solar Cell (DSC) is becoming a realistic approach towards energy markets such as BIPV (Building Integrated PhotoVoltaics). In order to improve the performances of DSCs and to increase their commercial attractiveness, cheap, colourful, stable and highly efficient ruthenium-free dyes must be developed. Here we report the synthesis and co...

Sensitized NiO based photocathode is a new field of investigation with increasing scientific interest in relation with the development of tandem dye-sensitized solar cells (photovoltaic) and dye-sensitized photoelectrosynthetic cells (solar fuel). We demonstrate herein that PbS quantum dots (QDs) represent promising inorganic sensitizers for NiO-based quantum dot-sensitized solar cells (QDSSCs)...

Conventional dye-sensitized solar cells have excellent charge collection efficiencies, high open-circuit voltages and good fill factors. However, dye-sensitized solar cells do not completely absorb all of the photons from the visible and near-infrared domain and consequently have lower short-circuit photocurrent densities than inorganic photovoltaic devices. Here, we present a new design where ...

Renewable energy sources are becoming imperative due to the high population, demand and depletion of fossil fuels. The solar cells play important role in this regard. third generation cell has semiconductor electrode, dye, electrolyte, surfactant counter electrode components. Among all components, dyes perform a primary absorbing converting it electrical storage capacity. efficiency working abs...

Autonomous sensing of metal ion contamination in remote environments with high reproducibility and sensitivity could unlock many new applications, but involves trade-offs between compactness, sensitivity, and power provisioning. In prior demonstrations of semi-autonomous sensors, the power source (e.g. a solar cell) was an additional component. Here, we demonstrate a concept, wherein a dye-sens...

Indacenodithiophene-core-based D–π–A-type organic sensitizers with two different donor antennas (triphenylamine and phenothiazine) were designed synthesized for use as light-harvesting materials in dye-sensitized solar cell (DSSC) applications.

Light scattering is a method that has been employed in dye-sensitized solar cells for optical absorption enhancement. In conventional dye-sensitized solar cells, large TiO(2) particles with sizes comparable to the wavelength of visible light are used as scatterers by either being mixed into the nanocrystalline film to generate light scattering or forming a scattering layer on the top of the nan...
