The transport and recombination of electrons in dye-sensitized TiO2 solar cells were studied by anal. of the current and voltage response to a small square-wave light-intensity modulation. Solar cells were studied under working conditions by using potentio ...
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 solar to electrical power conversion efficiency for dye-sensitized solar cells (DSCs) incorporating a solid-state organic hole-transporter can be over 5%. However, this is for devices significantly thinner than the optical depth of the active composite ...
The dye solar cell, is a novel photoelectrochemical solar cell presenting unique advantages, as the use of low cost materials and the potential simplicity of manufacturing. However, a liquid electrolyte is actually required for the transport of the photoge ...
Nanocryst. particles of ZnO and TiO2 of approx. equal size (∼15 nm) were used to prep. mesoporous electrodes for dye-sensitized solar cells. Electron transport in the solar cells was studied using intensity-modulated photocurrent spectroscopy and revealed ...
We investigate heterojunction photovoltaic devices using the carbocyanine 1,1'-diethyl-3,3,3',3'-tetramethylcarbocyanine perchlorate (Cy5) as donor and buckminsterfullerene (C60) as acceptor. We find that photocurrent generation occurs at the in ...
Hydrogenated microcrystalline silicon prepared at low temperatures by the glow discharge technique is examined here with respect to its role as a new thin-film photovoltaic absorber material. XRD and TEM characterizations reveal that microcrystalline silic ...
