Electrophoretic deposition of ZnO photoanode for plastic dye-sensitized solar cells

Plastic dye-sensitized solar cells have been fabricated based on an organic dye (D 149) and ZnO photoanode prepared via room temperature electrophoretic deposition (EPD) to yield a conversion efficiency of 4.17% under 100 mW cm^?2 AM 1.5 illumination. Intensity modulated photocurrent spectroscopy analyses reveal that the fabricated ZnO electrodes have adequate interparticle connection, even in the absence of any post-treatment. This study demonstrates that EPD is a convenient method for photoanode fabrication and ZnO photoelectrodes obtained via EPD are promising for efficient plastic solar cells.
