The electron transport and recombination in dye-sensitized TiO2 solar cells with different electrolytes have been investigated. The electrolytes were based on iodine-doped ionic liqs. (diethylmethylsulfonium iodide, dibutylmethylsulfonium iodide or 3-hexyl ...
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 electron transport in dye-sensitized solar cells with a MOCVD (metal org. vapor deposition)-grown ZnO nanorod array (ZnO-N) or a mesoporous film prepd. from ZnO colloids (ZnO-C) as the working electrode was compared. The electrodes were of similar thic ...
Through introducing an energy antenna system into a simple phenoxazine dye (TH301), a novel and efficient dye TH305 was designed and synthesized for application in a dye sensitized solar cell with prominent overall conversion efficiency of 7.7%. ...
Counter electrodes (CEs) of dye-sensitized solar cells (DSCs) can be prepared with different materials and methods. This review covers recent research on CEs using platinum, graphite, activated carbon, carbon black, single-wall carbon nanotubes, poly( 3,4- ...
A new method for the prepn. of nanostructured TiO2 films, based on the compression of a TiO2 powder is presented, and its relevance for the prodn. of dye-sensitized solar cells is discussed. By applying a pressure (>200 kg cm-2) on a film of TiO2 powder, a ...
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 ...
