Özet

Abstract – Manganese dioxide(MnO2) is a remarkable material used in various technological applications such as batteries, supercapacitors, and solar cells. Its low cost synthesis using simple methods and the absence of toxic components make MnO2 an attractive option for electronic applications. The morphology and crystal structure of MnO2 can be controlled through different synthesis methods. In this study, MnO2 nanoparticles were synthesized using a co-precipitation method. The crystal structure of the synthesized MnO2 nanoparticles was analyzed by X-ray diffraction (XRD), while their morphological properties were examined using scanning electron microscopy (SEM). The obtained MnO2 nanoparticles were incorporated into poly(3-hexylthiophene-2,5-diyl) (P3HT), which serves as a hole transport layer (HTL) in n-i-p structured perovskite solar cells, resulting in P3HT:MnO2 polymer nanocomposite layers. These P3HT:MnO2 polymer nanocomposite layers were formed on ITO/SnO2/MAPbI3 structures using a spin coating method. ITO/SnO2/MAPbI3/P3HT/Ag and ITO/SnO2/MAPbI3/P3HT:MnO2/Ag perovskite solar cells were fabricated. The current voltage (I-V) characteristics of the produced solar cells were investigated in the dark and under illumination. From the I-V characteristics obtained under illumination, photovoltaic parameters such as open circuit voltage (Voc) and short circuit current (Isc) were calculated. The Voc and Isc values for ITO/SnO2/MAPbI3/P3HT/Ag perovskite solar cells were obtained as 0.74 V and 1.5810-4 A, respectively. For ITO/SnO2/MAPbI3/P3HT:MnO2/Ag perovskite solar cells, Voc and Isc values were found to be 0.74 V and 2.0210-4 A, respectively. As a result, it was observed that the photovoltaic performance of the solar cells produced by doping MnO2 nanoparticles into the P3HT HTL layer in ITO/SnO2/MAPbI3/P3HT/Ag perovskite solar cells was improved.
