Nanofiber Semiconductor Experiment with Distance Variation Electrospinning Method to Improve DSSC Performance

Dye-Sensitized Solar Cell (DSSC) is a type of solar cell that uses dyes to transfer sunlight to electrical energy. DSSC construction uses a layered system (sandwich) that consisting of a working electrode and an opposing electrode, both of which are placed on conducting glass and electrolytes to allow electron cycling. This research aims to determine the effect of the distance between the tip and the rotating collector in an effort to increase the efficiency of Dye-Sensitized Solar Cell (DSSC) and examine its impact on the morphology of the ZnO nanofiber. This experiment is carried out by varying the distance between the tip to the rotating collector, which are 4 cm, 6 cm, and 8 cm. The results of this research indicates that at a distance of 8 cm it produces a small, uniform and regular ZnO nanofiber structure with Voc, Jsc, FF, and DSSC efficiency values of 0.559 V, 9.809 mA / cm2, 43.3% and 2.3%. In addition, at a distance of 8 cm it also produces the highest DSSC electrical efficiency from the other distances due to the absorbance of the dye and high electron excitation.
