Abstract Fully screen-printed perovskite solar cells represent a promising solution for scalable manufacturing of perovskite photovoltaics. However, their development is hindered by inefficient vertical phase transformation within thick, multi-layered films, which results in incomplete infiltration, premature surface nucleation and residual stress. Here we report a fluid motion crystallization strategy employing a co-solvent system of ionic liquid methylammonium propionate and butyronitrile.

Abstract Vacuum deposition is a promising route for the fabrication of perovskite solar cells (PSCs). However, vacuum-deposited PSCs have not yet matched the performance achieved by solution-processed devices. Here we improve the performance of fully vacuum-deposited PSCs by controlling the solid-state reaction pathway.

Abstract Thermal evaporation is a well-established technique in thin-film manufacturing and holds great promise for the scalable fabrication of perovskite solar cells. However, the performance of fully thermally evaporated perovskite solar cells lags behind that of solution-processed counterparts.
