We investigate the influences of photoanode on light scattering and absorption in a
dye-sensitized solar cell (DSSC). N719 dye on a monolayer anode of TiO2 film
and ZnO film, are compared in terms of their photovoltaic conversion efficiency.
Doctor blade application and high temperature sintering of photoanode assemblage
on indium doped tin oxide glass was adopted for preparation of the two
photoanodes. The optical density of the interfacial layer relative to the
photogenerated carriers is determined by absorption of ionic electrolytes. The
outcome obtained with different photosensitizing effect of organic
T.danielliimolecules on DSSCs showed a wide disparity, the highest Voc was
recorded with Br- with 500 mV and 79 mV respectively for TiO2 and ZnO
photoanode respectively. Three important morphological characterization
techniques were used, scanning electron microscopy (SEM) with energy dispersive
spectrum (EDS), Electron shell occupancy and Entropy were discussed in detail
with respect to their photoelectric performance, the best Iscwas 0.035 mA with Br-
on TiO2 attributable to a large optical density, achieved from ratio of area of
molecular coverage of nanoparticle film. Scanning electron microscopy (SEM)
revealed a structure consisting of direct and ordered paths for photogenerated
carriers to the collecting electrodes, the Pmaxresult reported was 36.54 mW with Br-
from TiO2
