Journal ArticleDOI

Chul Baik,Duckhyun Kim,Moon-Sung Kang,Sang Ook Kang,Jaejung Ko,Mohammad Khaja Nazeeruddin,Michael Grätzel +6 more
TL;DR: In this article, two novel trialkylsilyl-containing organic sensitizers (JK-53 and JK-54) were designed and synthesized for dye-sensitized solar cells.
Journal ArticleDOI
Interfacial electron transfer of flavin coenzymes and riboflavin adsorbed on textured TiO2 films
TL;DR: In this paper, the effect of the phosphate group on the adsorption of the flavins at the TiO 2 surface was investigated and was found to obey the Langmuir isotherm.
Journal ArticleDOI
Light induced H2 evolution in a hydrogenase-TiO2 particle system by direct electron transfer or via Rhodium complexes
TL;DR: Three different hydrogenases added to a suspension of TiO2 (anatase) powder are able to catalyze H2 evolution under band gap illumination of the semiconducting particles, and in the presence of EDTA or methanol as electron donor.
Journal ArticleDOI
Nanoscale interfacial engineering enables highly stable and efficient perovskite photovoltaics.

TL;DR: Chemical analysis of aged devices showed that molecular passivation suppresses interfacial ion diffusion and inhibits the photoinduced I2 release that irreversibly degrades the perovskite, indicating that interfacial engineering strategies enabled by multifunctional ligands can expedite the path towards stable PSCs.
Journal ArticleDOI
The influence of dye structure on charge recombination in dye-sensitized solar cells
TL;DR: Voltammetric measurements show that surface modification of FTO electrodes with Z-960 results in slightly more facile charge transfer to acceptor species in triiodide/iodide electrolytes in the dark, suggesting that surface adsorbed molecules bearing amino groups, including dye molecules, can catalyse charge recombination in dye-sensitized solar cells.
