In the context of the diminishing fossil energy resources and global warming, much research is focused on sustainable energy sources. The research that is presented in this thesis falls in this category as it contributes to the development of a device that ...
Novel org. dyes based on the phenothiazine (PTZ) chromophore were designed and synthesized for dye-sensitized solar cells, which give solar energy-to-electricity conversion efficiency (η)of up to 5.5% in comparison with the ref. Ru-complex (N3 dye) with an ...
Perhaps the largest challenge for our global society is to find ways to replace the slowly but inevitably vanishing fossil fuel supplies by renewable resources and, at the same time, avoid negative effects from the current energy system on climate, environ ...
The solar to electrical power conversion efficiency for dye-sensitized solar cells (DSCs) incorporating a solid-state organic hole-transporter can be over 5%. However, this is for devices significantly thinner than the optical depth of the active composite ...
Given the limitations of the materials available for photoelectrochemical water splitting, a multiphoton (tandem) approach is required to convert solar energy into hydrogen efficiently and durably. Here we investigate a promising system consisting of a hem ...
Naturally occurring photosynthetic systems in plants are supported by elaborate pathways of self-repair that limit the impact of photo-damage. Herein, we demonstrate a complex consisting of two recombinant proteins, phospholipids and a carbon nanotube that ...
Mesoscopic injection solar cells operate in an entirely different fashion than conventional solar p‐n junction devices. Mimicking the principles that natural photosynthesis has used successfully over the last 3·5 billion years in solar energy conversion, t ...
L'inconvénient de cellules du type photoélectrochimique (1) est que leur rendement est insuffisant pour une utilisation économique. L'invention a pour objet d'éliminer cet inconvénient. Selon l'invention, le procédé permet de réaliser une cellule photoélec ...
