Special Issue Information

Dear Colleagues,

We are pleased to announce a forthcoming Special Issue in Nanomaterials focused on “Thin Films for Efficient Perovskite Solar Cells”. This Special Issue aims to showcase and explore the latest breakthroughs in the synthesis, theoretical calculations, performance characterization, and applications of thin films in perovskite solar cells.

Perovskite solar cells (PSCs) have attracted extensive attention in recent years, and their certified power conversion efficiency has increased to over 26%, which is comparable to that of silicon solar cells and is expected to be a promising direction for a low-carbon society in the future. In recent decades, thin films, possessing a range of essential functions, have played and will continue to play a vital role in the development of high-performance PSCs.

This Special Issue aims to collect state-of-the-art pioneering contributions related to the synthesis, characterization, and application of thin films in efficient perovskite solar cells. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: innovative material designs and syntheses, interface engineering strategies, additive strategies and device architectures that enhance photovoltaic efficiency, stability and scalability. Thus, this Special Issue will showcase the latest advancements and promote interdisciplinary collaboration, accelerating the commercialization of perovskite-based technologies.

We look forward to receiving your contributions and witnessing the progress towards the Special Issue, “Thin Films for Efficient Perovskite Solar Cells” in Nanomaterials.

Dr. Xiaohui Liu

The tin dioxide (SnO2) thin films in this work were prepared by using plasma-enhanced atomic layer deposition (PEALD), and a systematic analysis was conducted to evaluate the influence of post-deposition annealing at various temperatures in a nitrogen–hydrogen mixed atmosphere on their surface morphology, optical behavior, and electrical performance. The SnO2 films were characterized by using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Hall effect measurements. With increasing annealing temperatures, the SnO2 films exhibited enhanced crystallinity, a higher oxygen vacancy (OV) peak area ratio, and improved mobility and carrier concentration. These enhancements make the annealed SnO2 films highly suitable as electron transport layers (ETLs) in perovskite solar cells (PSCs), providing practical guidance for the design of high-performance PSCs.
