Themed issue: nanomaterials for energy conversion and storage

Michael Graetzel, Kuppuswamy Kalyanasundaram

The rich and diverse aspect of nanomaterials for energy conversion and storage has been the research topic for many researchers. Photovoltaic solar cells for the direct conversion of sunlight to electricity can be grouped under three generations. One appro ...

Photonic and Optoelectronic Devices Based on Mesoscopic Thin Films

Michael Graetzel, Kuppuswamy Kalyanasundaram, Shaik Mohammed Zakeeruddin

Dye-sensitized solar cells (DSCs) are one of the most promising environmental friendly and low material costs photovoltaic devices. DSCs accomplish the separation of the optical absorption and charge separation processes by the association of a sensitizer ...

Artificial photosynthesis: biomimetic approaches to solar energy conversion and storage

Michael Graetzel, Kuppuswamy Kalyanasundaram

Using sun as the energy source, natural photosynthesis carries out a number of useful reactions such as oxidation of water to molecular oxygen and fixation of CO2 in the form of sugars. These are achieved through a series of light-induced multielectron-tra ...

Characterization of monomeric and gemini cationic amphiphilic molecules by fluorescence intensity and anisotropy

Kuppuswamy Kalyanasundaram, Guido Viscardi

Pyrene fluorescence intensity and conductivity measurements were used to determine the cmc of two monomeric surfactants namely, dodecyltrimethylammonium bromide and cetyltrimethylammonium bromide as well as two gemini surfactants, 16-3-16 2Br and 16-4-16 2 ...

White-light phosphorescence emission from a single molecule: application to OLED

Michael Graetzel, Kuppuswamy Kalyanasundaram, Mohammad Khaja Nazeeruddin, Filippo de Angelis

A simple mononuclear cyclometallated iridium(III) complex exhibits white photo- and electro-luminescence in the wavelength range from 440 to 800 nm, which originates from a single emitting excited state of mixed character. ...
