| Popis: | Sol–gel preparation method usually used to prepare the metal oxides. So, it is a rewarding process to prepare the electron selective film made of aluminum-doped titanium dioxide (Al-doped TiO2). The latter was used to fabricate the inverted organic solar cells P2HT:PCBM. The doping content with Al impact on the optical and morphological characteristics of each film were examined. These characteristics were analyzed depending on the magnified images of the prepared samples by atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray diffraction (XRD) in addition to the Uv-vis spectroscopic results. The outcomes revealed that the concentration of Al doping has potential influences on the optical properties, XRD results and surface morphology. The J–V curve characteristics of each solar cell utilizing Al–TiO2 film were analyzed and noticed that the most powerful conservation efficiency is 2.09% when using Al–TiO2 layer with 0.5 wt.% Al as a doping element. |
