First multi-wavelength campaign on the gamma-ray-loud active galaxy IC 310

Context. The extragalactic very-high-energy gamma-ray sky is rich in blazars. These are jetted active galactic nuclei that are viewed at a small angle to the line-of-sight. Only a handful of objects viewed at a larger angle are so far known to emit above 1 ...

The function of a TiO2 compact layer in dye-sensitized solar cells incorporating "Planar" organic dyes

Michael Graetzel, Udo Bach, Henry Snaith

We present a device based study into the operation of liquid electrolyte dye-sensitized solar cells (DSSC's) using organic dyes. We find that, for these systems, it is entirely necessary to employ a compact TiO2 layer between the transparent fluorine doped ...

A multi-colour sensitive device for color image sensing

Michael Graetzel, Udo Bach

A sensor element (1, 20, 21, 22) capable of sensing more than one spectral band of electromagnetic radiation with the same (x-y) spatial location, especially where the dimensions x-y-z form a set of Cartesian coordinates with z parallel to the direction of ...
