Rapid large-grain (>100 μm) formation of organic-inorganic perovskite thin films via shear deposition for photovoltaic application

[Display omitted] •High-speed (~5 mm·s−1) continuous solution-shearing method was introduced to fabricate the large grained (>100 μm) perovskite thin films and their photovoltaic devices.•Only 3.5 μL of perovskite precursor solution was consumed for 4.25 cm2 film so that this shearing deposition...
