Abstract
In this article, work was carried out to optimize the thickness of the photoactive layer in inverted solar cells based on ZnO. Fluorine-doped tin oxide (FTO)/ZnO/P3HT:PCBM/MoO3/Ag organic solar cells were fabricated and characterized. The influence of the thickness of the photoactive layer on the morphology, optical and photoelectric properties of the solar cell has been studied. The surface topography of P3HT:PCBM was examined using atomic force microscopy (AFM). Increasing the thickness of the photoactive layer leads to an increase in the roughness of the film surface. Optical absorption spectra were measured. An increasing trend in absorption was clearly observed when moving from a thinner 85 nm film to a thicker 210 nm film. The P3HT:PCBM film thickness was optimized when deposited at various substrate rotation speeds, with the film produced at 500 rpm achieving a maximum photoconversion efficiency of 1.8%.
