Description
Summary:Low production cost and ever-increasing efficiencies make perovskite solar cells a flourishing area of research. The high efficiency originates from not only the unique optoelectronic properties of perovskites, but also various device optimization strategies, such as interfacial engineering, defect engineering, and componential engineering. Behind these strategies stand the fundamental intermolecular interactions and bondings, such as hydrogen bonding, halide bonding, ionic bonding, Lewis acid-base interactions, and van der Waals interactions. In this review, we focus on different types of interactions and summarize the progresses made in perovskite solar cells. Additionally, perspectives on further efforts in improving device performance and stability are presented. Various intermolecular interactions in perovskite solar cells can help in improving efficiency and stability.
