Dynamics in next-generation solar cells: time-resolved surface photovoltage measurements of quantum dots chemically linked to ZnO (10 10) Ben F. Spencer,* Matthew J. Cliffe, Darren M. Graham, Samantha J. O. Hardman, Elaine A. Seddon, Karen L. Syres, Andrew G. Thomas, Fausto Sirotti, Mathieu G. Silly, Javeed Akhtar, Paul O'Brien, Simon M. Fairclough, Jason M. Smith, Swapan Chattopadhyay and Wend...
Plasmonic crystal effects analogous to photonic crystal phenomena such as zone folding and gap opening were observed for edge magnetoplasmons in a two-dimensional electron system with a periodically corrugated boundary at microwave frequencies. Magnetic field dependent photovoltage data provide unequivocal evidence for Bragg reflection. Band gaps up to fifth order were observed. These gaps were...
A model system of nanoporous TiO2 sensitized with dye molecules at the outer surface is investigated by time resolved surface photovoltage SPV at temperatures between −120 °C and 270 °C to get information about electron diffusion over more than 10 orders of magnitude in time. The SPV transients increase in time due to independent electron diffusion and reach a maximum at a certain peak time due...
Porous ZnO electrodes on fluorine-doped tin oxide (FTO) were prepared by electrochemical deposition from an O(2)-saturated ZnCl(2) solution in the presence of eosin Y as a structure directing agent (SDA). Sensitization was reached by desorption of the SDA and subsequent adsorption of the indoline dye D149. The influence of film thickness and dye concentration in the films on their photovoltaic ...
A composite film of nickel sulfide/platinum/titanium foil (NiS/Pt/Ti) with low cost and high electrocatalytic activity was synthesized by the use of an in situ electropolymerization route and proposed as a counter electrode (CE) catalyst for flexible dye-sensitized solar cells (FDSSCs). The FDSSC with the NiS/Pt/Ti CE exhibited a comparable power conversion efficiency of 7.20% to the FDSSC with...
