“…Several studies approved that incorporation of organometallic molecules with different atoms will improve their physical and chemical features. In general, organometallics can be easily doped with metals, metal oxides or carbonaceous materials producing nanocomposite with promising aspects [6,7]. Dasi et al (2022) have prepared Alq 3 /ZnO thin film by sol-gel spin coating for improving the physical properties of the nanocomposite [8].…”

The global demand for renewable energy as an alternative to traditional fossil fuels has motivated the scientific community to develop highly efficient nanocomposite materials that can be used for enhancement to optoelectronic technology. In the present work, organometallics Alq3 and Alq3/CNTs were prepared by cost-effective chemical route. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were performed to identify the structural and morphological features. The hybrid Alq3/CNTs exhibited polycrystalline structure with a large surface area. The optical band gap (E_g) of Alq3 film was evaluated within the visible spectrum in the range of 3.047 eV which reduced to 2.979 eV by CNTs integration. Ag/Alq3/p-Si/Al and Ag/Alq3/CNTs/p-Si/Al photodiodes were fabricated using thermal evaporating technique. Current-voltage (I-V) and capacitance/conductance-voltage (C/G-V) were measured to analyze the photodiode behavior. The main electronic parameters like R_s,n,ϕ_b 〖and I〗_o were determined using different models indicating that the composite photodiode of high performance in which R_s was decreased whereas N_a was increased with doping. Besides, the photocurrent sensitivity was increased from 1.45×〖10〗^(-8) A to 1.1 ×〖10〗^(-5) A due to increase of free charge carriers.
