Metal-free org. dyes with a core phenoxazine chromophore have been synthesized and tested as sensitizers in dye-sensitized solar cells. Overall conversion efficiencies of 6.03-7.40% were reached under std. AM 1.5 G illumination at a light intensity of 100 ...
Photo-induced charge separation and charge transport are fundamental processes in many energy conversion techniques, where light is converted into chemical energy (PEC), into electrical energy (solar cells) or in the opposite sense if electrical energy is ...
Tools that assess the limitations of dye sensitized solar cells (DSSCs) made with new materials are critical for progress. Measuring the transient electrical signals (voltage or current) after optically perturbing a DSSC is an approach which can give infor ...
Mesoscopic sensitized solar cells are one of the most promising third-generation photovoltaic technologies. Dye-sensitized solar cells (DSCs), imitating the photosynthesis of green plants, were the first photovoltaic devices to utilize a mesoscopic heteroj ...
A fully conjugated unsymmetrical dimeric squaraine dye was synthesized. The synthetic key step for this dye, a selective Knoevenagel type condensation of end groups to the core moiety, allows the incorporation of a carboxylic acid function essentially for ...
TiO2 were doped with MgO by thermal hydrolysis, The photoelectrochem. properties of the 1%MgO-doped TiO2 film matched with org. dye TH305 were better than those of the anatase TiO2 film. The conduction band of the MgO doped nanostructured TiO2 synthesized ...
A perylene sensitizer, ID176, was recently reported which performs much better in solid state dye-sensitized solar cells than in those using liq. electrolytes with iodide/tri-iodide as the redox couple. Here, a characterization is presented of the sensitiz ...
We report the results of an investigation on the preparation, spectral and photoelectrochemical properties of alkyne bridged dendron chromophores with carboxylic acid anchoring group, which adhere effectively to nanocrystalline (anatase) TiO2 surfaces yiel ...
A direct-bonded GaAs/InGaAs solar cell is demonstrated. The direct-bonded interconnect between subcells of this two-junction cell enables monolithic interconnection without threading dislocations and planar defects that typically arise during lattice-misma ...
The relation between the VOC, light intensity, φ, and accumulated charge, Q, was studied for dye-sensitized solar cells (DSCs) contg. different counterions for the iodide/triiodide redox couple. At higher light intensities, VOC scaled in the order Cs+ > K+ ...
