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 ...
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 ...
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 ...
A solid state p-n heterojunction comprising an electron conductor and a hole conductor it further comprises a sensitising semiconductor, said sensitizing semiconductor being located at an interface between said electron conductor and said hole conductor. I ...
The objective of this work was to develop a solid-state dye-sensitized solar cell, in which the liquid electrolyte, commonly applied in photoelectrochemical cells, is replaced by a solid organic charge transport material (spiro-OMeTAD). The dye-sensitized ...
