Special Issue Information

Dear Colleagues,

Solar energy has undeniably risen to prominence as a central domain within the realm of renewable energy technologies. The solar power landscape has, in recent years, witnessed significant advancements across various photovoltaic technologies. These encompass crystalline silicon cells, thin-film technologies, organic solar cells, perovskite cells, and other emerging photovoltaic platforms. At the core of these technologies lies the fundamental principle of photovoltaic mechanisms. In this process, an active layer directly converts sunlight into electrons, while the charge-transporting layer facilitates their movement within the circuit. Notably, nanomaterials have assumed a pivotal role in enhancing the performance of photovoltaics, contributing to the advancement of functional materials, device physics, and novel structural designs.

We are pleased to announce our forthcoming Special Issue, “Nanomaterials for Photovoltaic System Applications”, which has been designed to highlight cutting-edge research papers and comprehensive review articles from the global research community. We extend a cordial invitation to researchers and innovators to submit their original work exploring the multifaceted role of nanomaterials in the realm of photovoltaic applications. Topics of interest include, but are not confined to, interface and layer enhancements, deposition technology optimizations, innovative structural designs, and a wide array of applications.

We eagerly await your invaluable contributions.

Due to current issues of energy-level mismatch and low transport efficiency in commonly used electron transport layers (ETLs), such as TiO2 and SnO2, finding a more effective method to passivate the ETL and perovskite interface has become an urgent matter. In this work, we integrated a new material, the ionic liquid (IL) hexylammonium acetate (HAAc), into the SnO2/perovskite interface to improve performance via the improvement of perovskite quality formed by the two-step method. The IL anions fill oxygen vacancy defects in SnO2, while the IL cations interact chemically with Pb2+ within the perovskite structure, reducing defects and optimizing the morphology of the perovskite film such that the energy levels of the ETL and perovskite become better matched. Consequently, the decrease in non-radiative recombination promotes enhanced electron transport efficiency. Utilizing HAAc, we successfully regulated the morphology and defect states of the perovskite layer, resulting in devices surpassing 24% efficiency. This research breakthrough not only introduces a novel material but also propels the utilization of ILs in enhancing the performance of perovskite photovoltaic systems using two-step synthesis.
