Abstract

This chapter discusses the importance and impact of metal halide additives into perovskite to enhance its semiconductor quality and realize highly efficient and stable perovskite photovoltaic devices. Monovalent metal halides have been introduced as the most promising candidates due to their loading capacity and chemical compatibility with the perovskite materials, as well as ease of incorporation and their remarkable positive impact on the crystal growth, optoelectronic properties, and subsequently the performance of perovskite solar cells (PSCs). Among all the monovalent metal cations, Cs is the only one that could fit in the perovskite structure and forms photoactive perovskite. The other monovalent cations are located at the interstitials sites, grain boundaries, and crystalline surfaces. We also discuss the key roles of monovalent metal halide additives that include modulating morphology of perovskite films, modification of structural and optoelectronic properties, adjusting energy level alignment in PSCs, inhibiting non-radiative recombination in perovskites, eliminating hysteresis, and enhancing operational stability of PSCs.
