The Role of Organic Amidiniums in Perovskite Photovoltaics

Abstract

Clean energy forms the foundation of sustainable development, and among various technologies, photovoltaics─directly converting sunlight into electricity─stand out as one of the most promising and impactful. In recent years, it has garnered significant attention and undergone rapid development. Notably, Organic–inorganic Lead Halide Perovskites (OLHPs) have emerged as a breakthrough in this field. After just a decade of research and development, OLHP-based solar cells have achieved power conversion efficiencies (PCEs) exceeding 26%. OLHPs offer a unique combination of solution-based processing, low-cost production, and high efficiency, making them strong competitors to traditional inorganic semiconductor technologies such as silicon-based photovoltaics.
