and Abstract My project this summer took place in the lab of Dr. in the Oxford Physics Department. I worked for ten weeks on solid-state dye-sensitized solar cells that incorporated the polymer hole-transporter poly(3-hexylthiopene) (P3HT) and a number of different dyes. The larger goal of the project is to extend solid-state solar cells' photoresponse by taking advantage of a favorable energy-...

In the present study, protoporphyrin IX (PPIX) and squarine (SQ2) have been used in a co-sensitized dye-sensitized solar cell (DSSC) to apply their high absorption coefficients in the visible and NIR region of the solar spectrum and to probe the possibility of Förster resonance energy transfer (FRET) between the two dyes. FRET from the donor PPIX to acceptor SQ2 was observed from detailed inves...

The structure of the dye layer adsorbed on the titania substrate in a dye-sensitized solar cell is of fundamental importance for the function of the cell, since it strongly influences the injection of photoelectrons from the excited dye molecules into the titania substrate. The adsorption isotherms of the N719 ruthenium-based dye were determined both with a direct method using the depth profili...

A vertically aligned carbon nanofiber array coated with anatase TiO(2) (CNF/TiO(2)) is an attractive possible replacement for the sintered TiO(2) nanoparticle network in the original dye-sensitized solar cell (DSSC) design due to the potential for improved charge transport and reduced charge recombination. Although the reported efficiency of 1.1% in these modified DSSC's is encouraging, the lim...
