The intra-molecular charge transfer electronic transition in a series of D-π-A metal complexes dyes which could be used as sensitizers in DSSCs have been studied utilizing the TD-DFT method. The structure of these dyes are shown in figure 1, where different π-spacers (S) namely; benzene, furan, pyrrole and thiophene have been assigned. The transition metals(More)
The pure physical approach used to characterise thermal comfort is not informative for many urban designers and landscape architects. Significantly, this theoretical approach was criticised due to the lack of consideration of human sensations ad perceptions. Recent researches show an increased consideration for psychological and behavioural aspects of(More)
The geometrical, conformational, and electronic properties of a series of D-π-A metal-free dyes designed for use as sensitizers in DSSCs were studied using DFT and TD-DFT methods. A substituted triphenylamine moiety was used as the donor group and 2-cyanoacrylic acid as the acceptor group in these dyes. They also contained conjugated bridging π-linker(More)
