Abstract
Well crystalline ZnO rectangular prism (ZnO-RP) nanomaterials were synthesized by a low temperature solution process and employed as photoanode materials for the dye sensitized solar cells (DSSCs). Synthesized nanomaterials featured the define rectangular prism morphology with the average thickness of similar to 100 nm and possessed typical hexagonal wurtzite structure. ZnO-RP photoanode presented a reasonable conversion efficiency (eta) of similar to 33% along with high short circuit current (J(SC)) of similar to 8.91 mA/cm(2), open circuit voltage (V-OC) of similar to 0.725 V and fill factor (FF) of similar to 0.51 in DSSC The rectangular shape of ZnO could provide high surface to volume ratio for dye absorption and light harvesting efficiency, which significantly resulted in high J(SO) and conversion efficiency of DSSC.
