Abstract

Perovskite solar cells (PSCs) have witnessed great advancements in power conversion efficiency (PCE) and stability. Over the past several years, various nonhalide materials have been extensively developed to enhance both PCE and stability by including them in perovskite compositions, perovskite precursor materials, additives, post-treatment reagents, dopants for charge transport materials (CTMs), CTMs, and interfacial modifiers. In this review, various nonhalide materials reported for PSCs are described and the dependence of the photovoltaic performance on anions (or in part cations) in nonhalide materials is investigated. This review highlights the importance of synergistic and rational engineering of anions and cations of the nonhalide materials in order to maximize both PCE and stability of PSCs.
