Design Optimization of Cesium Contents for Mixed Cation MA1−xCsxPbI3-Based Efficient Perovskite Solar Cell
Published on 2025-07-13 by Syed Abdul Moiz, Ahmed N. M. Alahmadi, Mohammed Saleh Alshaikh @MDPI
Abstract: Perovskite solar cells (PSCs) have already been reported as a promising alternative to traditional energy sources due to their excellent power conversion efficiency, affordability, and versatility, which is particularly relevant considering the growing worldwide demand for energy and increasing scarcity of natural resources. However, operational concerns under environmental stresses hinder its economic feasibility. Through the addition of cesium (Cs), this study investigates how to optimize pero[...]

Abstract: Flexible perovskite solar cells (FPSCs) hold great promise for lightweight and wearable photovoltaics, but improving their efficiency and durability under mechanical stress remains a key challenge. In this work, we fabricate and characterize flexible planar FPSCs on a polyethylene terephthalate (PET). A phenethylammonium iodide (PEAI) surface passivation layer is introduced on the perovskite to form a two-dimensional capping layer, and its impact on device performance and stability is systematic[...]
Our summary: Enhanced efficiency and mechanical stability achieved in flexible perovskite solar cells through PEAI surface passivation, leading to improved device performance and durability under mechanical stress. Integration of PEAI treatment with optimized ETL and HTL layers enhances efficiency and flexibility, paving the way for reliable and high-performance wearable solar cells.

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.
