Solution-based synthesis of CsSnI₃

摘要

This invention discloses a solution-based synthesis of cesium tin tri-iodide (CsSnI3) film. More specifically, the invention is directed to a solution-based drop-coating synthesis of cesium tin tri-iodide (CsSnI3) films. CsSnI3 films are ideally suited for a wide range of applications such as light emitting and photovoltaic devices.

主权项

1. A process of forming CsSnI3 film on a substrate, comprising steps of:
(a)providing a substrate; (b)providing homogeneous CsSnI3 solution; (c)drop-coating the homogeneous CsSnI3 solution onto the substrate; (d)heating the substrate after step (c) to remove solvent in the homogeneous CsSnI3solution until the substrate is dry; and (e)forming the CsSnI3film on the substrate.
