Solar technologies have become increasingly advanced over the years, with the discovery of new photovoltaic materials and designs. While solar cells based on a mixture of organic and inorganic halide perovskite materials have been the topic of numerous research studies and achieved promising performances, these cells are often difficult to fabricate on a large-scale.

Researchers at Chonnam University in South Korea recently introduced an alternative solar cell design fully based on inorganic perovskites. Their solar cells, introduced in Nature Energy, could be easier to fabricate on a large-scale, while nonetheless achieving promising power conversion efficiencies (PCEs).
