Electron Transportand Recombination in Dye Sensitized Solar Cells Fabricated from Obliquely Sputter Deposited and Thermally Annealed
Waita, S M; Aduda, BO; Mwabora, JM; Granqvist, CG; Lindquist, SE; Niklasson, G A; Hagfeldt, A; Boaschloo, G (School of Physical Sciences, 2007)This study investigated the effectiveness of three physical-chemical methods namely; pH adjustment, precipitation with alum and the use of polyelectrolytes. In the treatment of diary wastewater from Brookeside milk processing ... -
Interpretation of small-modulation photocurrent transients in dye-sensitized solar cells – A film thickness study
Nissfolka, J; Fredin, K; Simiyu, J; Häggman, L; Hagfeldt, A; Boschloo, G (Department of Physics, College of Biological and Physical sciences, University of Nairobi, 2010)Electron transport in dye-sensitized solar cells with varying mesoporous TiO2 film thicknesses was investigated using experimental and computational methods. More specifically, photocurrent transients resulting from ... -
Titania Nanotubes Prepared by Synthesis Method for Dye Sensitized Electrochemical Solar Cells
Simiyu, J; Mwabora, JM; Aduda, Bernard O; Lindquist, SE; Hagfeldt, A; Boschloo, G (University of Nairobi, KenyaUppsala University, Department of Physical Chemistry, Uppsala, Sweden, 2008)The area of nanostructured materials for dye sensitized solar cells has gained great interest especially after a breakthrough by Gratzel and coworkers in developing a solar cell from nanostructured oxide of titania ...
