A new ZnO nanotetrapods/SnO2 nanoparticles composite photoanode for high efficiency flexible dye-sensitized solar cells.
We report a new photoanode for flexible dye sensitized solar cells based on a judicious combination of SnO(2) nanoparticles and ZnO nanotetrapods and the development of an effective low temperature fabrication technique of "acetic acid gelation-mechanical press-ammonia activation". A 4.91% efficiency has been achieved on an ITO-coated polyethylenenaphthalate (ITO/PEN) substrate under 1 sun equi...
متن کاملFlexible Dye-Sensitized Nanocrystalline TiO2 Solar Cells
The Dye-sensitized nanocrystaline TiO2 solar cell (nc-DSC) developed by Grätzel [1] has the potential to reach low costs in future outdoor power applications. In addition, due to its expected ease of production and possibilities to adjust its appearance, the potential for application is very broad. When plastic foil is used as a substrate for the nc-DSC the production and application possibilit...
متن کاملHigh performance organic photosensitizers for dye-sensitized solar cells.
We report highly efficient organic photosensitizers containing pi-conjugated alkoxy-substituted oligophenylenevinylene linkers with electron donor-acceptor units for dye-sensitized solar cells. TA-DM-CA showed an overall solar-to-energy conversion efficiency of 9.67% at AM 1.5 illumination (100 mW cm(-2)).
متن کاملTemperature effects in dye-sensitized solar cells.
In the standard solar cell technologies such as crystalline silicon and cadmium telluride, increments of temperature in the cell produce large variations in the energy conversion efficiency, which decreases at a constant rate. In dye solar cells the efficiency remains roughly constant with a maximum at around 30-40 °C and further decays above this temperature. In this work, the origin of this c...
متن کاملZnO@SnO2 engineered composite photoanodes for dye sensitized solar cells
Layered multi-oxide concept was applied for fabrication of photoanodes for dye-sensitized solar cells based on ZnO and SnO2, capitalizing on the beneficial properties of each oxide. The effect of different combinations of ZnO@SnO2 layers was investigated, aimed at exploiting the high carrier mobility provided by the ZnO and the higher stability under UV irradiation pledged by SnO2. Bi-oxide pho...
