Measurement of Ultrafast Photoinduced Electron Transfer from Chemically Anchored Ru-Dye Molecules into Empty Electronic States in a Colloidal Anatase TiO2 Film
TL;DR: The electron transfer reaction reported in this article did not involve redistribution of vibrational excitation energy and was thus completely different from the well-known Marcus−Levich−Jortner−Gerischer type of electron transfer in the case of weak electronic interaction.

Origin of Photovoltage and Photocurrent in the Nanoporous Dye-Sensitized Electrochemical Solar Cell
Klaus Schwarzburg,Frank Willig +1 more
TL;DR: In this article, the essential role of the dark equilibrium potential for charge separation and the photovoltaic functioning of the title cell is discussed and a quantitative model is presented for the potential distribution in the sponge-type title cell.

Experimental fingerprints of vibrational wave-packet motion during ultrafast heterogeneous electron transfer.
C. Zimmermann,Frank Willig,S. Ramakrishna,B. Burfeindt,Bruno Pettinger,Rainer Eichberger,Winfried Storck +6 more
TL;DR: By application of 20 fs laser pulses, vibrational wave packets of low-energy modes (mainly 357 and 421 cm-1) were generated in the perylene chromophore that gave rise to periodic beats that lasted...

Formation of uniform size anatase nanocrystals from bis(ammonium lactato)titanium dihydroxide by thermohydrolysis
TL;DR: In this paper, it was shown that the size of anatase nanocrystals is mainly determined by the reaction temperature, increasing from ca 2nm at 120°C to about 20nm at 300°C, indicating that Ostwald ripening has now become effective.

Ultrafast electron injection from excited dye molecules into semiconductor electrodes
Rainer Eichberger,Frank Willig +1 more
TL;DR: In this article, the authors measured the fluorescence decay of adsorbed dye molecules on semiconductor electrodes where their stationary photoelectrochemical current approaches the yield of one electron per absorbed photon, also on solids where injection cannot occur and finally on a semiconductor where the current yield is low.
