Layered gamma-zirconium phosphate as novel semiconductor for dye sensitized solar cells: Improvement of photovoltaic efficiency by intercalation of a ruthenium complex-viologen dyad

Atienzar Corvillo, Pedro Enrique; De Victoria-Rodriguez, Maria; Juanes, Olga; Rodríguez-Ubis, J.C.; Brunet, E.; García Gómez, Hermenegildo (Royal Society of Chemistry, 2011-11)

[EN] The performance of photovoltaic cells using as semiconductor a film of layered γ-zirconium phosphate (γ-ZrP) containing Ru(bpy) 3 and bipyridinium ions (viologens) as electron relays has been studied. The materials ...
Photochemistry of charge-transfer complexes in a viologen periodic mesoporous organosilica: Time evolution from femtoseconds to minutes

Alvaro Rodríguez, Maria Mercedes; Ferrer Ribera, Rosa Belén; García Gómez, Hermenegildo; Hashimoto, Shuichi; Hiratsuka, Masahiro; Asahi, Tsuyoshi; Masuhara, Hiroshi (Wiley-VCH Verlag, 2014-07)

Persistent radical cations can be generated in V∝PMO, a periodic mesoporous organosilica incorporating a viologen in its silicate framework. Photoexcitation of V∝PMO forms a geminate viologen–halide ion pair that can undergo ...
