Introduction Click to copy section linkSection link copied! Since the pioneering work of Miyasaka in 2009, (1) introducing perovskites as a light-harvesting material in dye-sensitized solar cells, research on perovskite solar cells (PSCs) has expanded at an exceptional pace. The power conversion efficiency (PCE) has progressed from 3.9% to 10% in solid-state configurations (2,3) and has more recently approached a remarkable 27.0%.

High quality MAPbBr3 films via pulsed laser deposition of single-crystalline targets High quality MAPbBr3 films were grown by pulsed laser deposition of single-crystalline targets using an on-axis geometry. The gas ambient up to the mbar range and laser fluence of some tenths of joule per square centimeter yielded to single α-phase polycrystalline MAPbBr3 films, as revealed by ex-situ XRD analysis.

Physical and chemical properties and degradation of MAPbBr3 films on transparent substrates To date, the potential exploitation of hybrid organic-inorganic perovskites (HOIPs) in photovoltaic technologies has been significantly hampered by their poor environmental stability. HOIP degradation can be triggered by conventional operational environments, with excessive heating and exposure to oxygen and moisture significantly reducing the performances of HOIP-based solar cells.
