  1. 1. Interactions in Dye-sensitized Solar Cells

    Author : Helena Greijer Agrell; Anders Hagfeldt; Gerrit Boschloo; Laurence Peter; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; solar cells; photovoltaics; dye-sensitized; mesoporous; nanostructured; Raman scattering; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Abstract : The interactions between the molecular constituents in dye-sensitized solar cells were studied with UV-VIS and IR spectroscopy, Raman scattering, conductivity and electron accumulation measurements.From stability studies of the dye, bis(tetrabutylammonium)cis-bis(thiocyanato) bis(2,2’-bipyridine-4-carboxylic acid, 4’-carboxylate) ruthenium(II), in the complete solar cell, the thiocyanate ion ligand was found to be lost from the dye.
