Abstract
Organic/inorganic hybrid lead halide perovskite solar cells have recently emerged as the forerunner in the next generation of photovoltaic technology due to unprecedented progress in power conversion efficiency from their debut of 3.8% in 2009 to the currently certified 23.3%. Mixed PSC solar cells are subject to compositional degradation when exposed to ambient surroundings, which thwarts their real-world applications. Moreover, lead-based compounds pose environmental/health hazards. Very recently, all-inorganic lead-free perovskites have attracted enormous attention because this type successfully dismantles two roadblocks—instability and toxicity, which would accelerate the commercialization. In this outlook, we offered our perspective on the most recent developments in material sciences of halides all inorganic perovskites with possible alternatives to lead, the synthesis approaches, assessment of various device configurations and their progress in solar cells. For the sake of comparison, we also reviewed some all-inorganic but lead-based counterparts in order to motivate researchers to explore all the potentials. Surveying recent developments toward lead-free all-inorganic perovskite solar cells would offer a roadmap for developing new materials and navigate uncharted territory in solar energy fields.
