Book ChapterDOI
Photovoltaic Cells for Sustainable Energy
TL;DR: In this article, the history, technology and applications of photovoltaic devices and their applications are reviewed and a review of their history, technologies and applications are presented. But only nuclear and geothermal sources are non-solar.
Book ChapterDOI
Interfacial Electron Transfer in Dye Sensitised Nanocrystalline TiO 2 Films
TL;DR: The sensitivity of wide band gap semiconductors to visible irradiation by the adsorption of dyes to their surface is of widespread technological importance recently photoelectrochemical solar cells have been developed based upon dye sensitised nanocrystalline titanium dixoide (TiO2) thin films.
Book ChapterDOI
Dynamics of Interfacial Electron Transfer Reactions in Colloidal Semiconductor Systems and Water Cleavage by Visible Light
TL;DR: In this article, the authors present recent results concerning the nature and reactivity of charge carriers in colloidal semiconductor particles using laser photolysis technique with picosecond time resolution, and they have been able to monitor directly the dynamics of fundamental processes such as charge carrier trapping and recombination.
Journal ArticleDOI
Introducing rigid π-conjugated peripheral substituents in phthalocyanines for DSSCs
Lara Tejerina,Esmeralda Caballero,M. Victoria Martínez-Díaz,Mohammad Khaja Nazeeruddin,Michael Grätzel,Tomás Torres,Tomás Torres +6 more
TL;DR: A new carboxy-Zn(II)phthalocyanine bearing rigid 2,6-diarylphenyl peripheral substituents linked to the macrocycle through alkynyl spacers has been prepared by a convergent approach, which implies a triple Sonogashira coupling between the formyltriiodoZnPc and the corresponding terminal alkyne.
Journal ArticleDOI
Determination of the surface concentration of crown ethers in supported lipid membranes by capacitance measurements
TL;DR: The attachment of a tetradecyl chain to the ionophore 18-crown-6 leads to a stronger interaction with a supported lipid monolayer as discussed by the authors, which is used to produce ionophores contg. at the surface of an electrode.
