Strategically synthesized spinel NiCo2O4 material as suitable hole transporting layer for lead-free perovskite solar cells
Conv. Ctr. Room 8
Abstract
The hole transport layer (HTL) plays a very significant role in the performance of perovskite solar cells (PSCs). However, the selection of appropriate HTL is crucial to realizing the stability, cost, and device efficiency of PSCs. In this study, initially, NiCO2O4 structures were synthesized via a hydrothermal route. Further, various characterization techniques were employed to analyze the synthesized materials, including UV-vis spectroscopy (UV), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy. The crystal structure, band gap, elemental mapping, surface morphology, site-specific structural, and electronic state of the atom were investigated using XRD, UV, FESEM, TEM, and XPS, respectively. Furthermore, all inorganic lead-free PSC was developed using the spin-coating technique and exhibited improved PCE with spinel NiCO2O4 hole transporting material.
