Effect of dye coating duration of eosin Y synthesized on nanorods zinc oxide toward hybrid solar cell

The efficiency of inverted organic solar cells become interested among researchers. The various parameters changed to improve the efficiency of cell. This study were conducted to investigate the effect of dye coating duration on the performance of inverted organic solar cell. The characterization of the sample was done by Scanning Electron Microscope test (SEM) for morphology characterization, UV-Vis-NIR test for optical properties and current voltage test (IV) to determine the efficiency. The ZnO nanorods-coated FTO substrates were immersed in the eosin Y dye solution with ethanol at 60^oC for 15, 60 and 120 minute. The power conversion efficiency of the solar cell increased with dye coating duration and reached an optimum value at dye coating duration of 60 minute. The device with dye coating duration of 60 minute exhibited the highest power conversion efficiency of 0.0001528 % with short I_sc 0.00765 mA/cm², V_oc of 0.192 V and fill factor of 0.104 %.
