We report on the effect of substituting the two tetrabutyl ammonium counter ions of the standard N719 dye by sodium ions on the performance and stability of dye-sensitized solar cells (DSCs). The disodium analogue of N719 in conjunction with a non-volatile ...
The effect of exposing cyanine–fullerene C60 bilayer solar cells to ambient atmosphere is investigated. For exposure times of a few hours and concomitant light soaking, the device performance experiences a drastic power efficiency increase going from 0.14% ...
Dye-sensitized solar cells (DSCs) constitute a novel class of hybrid organic-inorganic solar cells. At the heart of the device is a mesoporous film of titanium dioxide (TiO2) nanoparticles, which are coated with a monolayer of dye sensitive to the visible ...
Solid-state nanocrystalline solar cells composed of chemical-bath-deposited Sb2S3 (antimony sulfide) as a light absorber layer deposited on nano-porous TiO2 and spiro-MeOTAD as an organic hole-transporting material yielded a solar conversion efficiency of ...
Although in principle very promising, photovoltaic technology has so far failed to deliver robust high efficiency modules at affordable prices. Despite considerable research, high efficiency silicon based cells remain expensive, while the more recent organ ...
Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
The photoelectrochem. properties of ZnO electrodes were studied in the near-UV region. Studies were carried out on electrodes with different morphologies, porosities, and film thicknesses to probe the influence of these parameters on the photoelectrochem. ...
Photoelectrochem. properties of nanostructured ZnO thin film electrodes have been investigated in the UV and visible regions. For films consisting of 15 nm large undoped crystallites a max. monochromatic current conversion efficiency of 58% was obtained in ...
