Characterization of anthocyanin dyes and investigation of charge transport in tio2 dye sensitized solar cells
Simiyu, Justus (University of NairobiPhysics, 2010-09)TiO2 dye sensitized electrochemical solar cells employing naturally occurring anthocyanin dye pigment have been fabricated. The films were coated by screen-printing method from P25 Degussa as the starting material. ... -
Sensitization and stability studies of anthocyanin based sensitization dyes on nanoporous ti02 thin film photoelectrochemical solar cells
Simiyu, Justus (2002)Dye sensitized Ti02 solar cells have been prepared by the sol gel process. Three groups of naturally occurring anthocyanin dye pigments have been extracted and tested for sensitization alongside ruthenium complex (RuL, ...
