Enhanced Charge Transport in Inverted Perovskite Solar Cells via Electrodeposited La-Modified NiOx Layers
Published on 2025-07-08 by Lina Aristiz�bal-Duarte, Mart�n Gonz�lez-Hern�ndez, Sergio E. Reyes, J. A. Ram�rez-Rinc�n, Pablo Ortiz, Mar�a T. Cort�s @MDPI
Abstract: This work explored an electrochemical approach for synthesizing lanthanum-modified nickel oxide (NiOx:La) as a hole transport layer (HTL) in inverted perovskite solar cells (IPSCs). By varying the La3+ concentration, the chemical, charge transport, structural, and morphological properties of the NiOx:La film and the HTL/PVK interface were evaluated to enhance photovoltaic performance. X-ray photoelectron spectroscopy (XPS) confirmed La3+ incorporation, a higher Ni3+/Ni3+ ratio, and a valence ban[...]
Our summary: Electrodeposited NiOx:La layers were explored as a hole transport layer in inverted perovskite solar cells, showing enhanced charge transport and improved photovoltaic performance. XPS confirmed La3+ incorporation and improved p-type conductivity, while impedance spectroscopy indicated lower resistance and higher carrier density with NiOx:La 0.5%. The resulting cell achieved a PCE of 20.08% and retained 80% of its initial efficiency after 50 days, demonstrating the potential of NiOx:La as a promising HTL for efficient and stable IPSCs.
