The mesoscopic ITO PSCs have a unique structure,  composed of three mesoporous layers containing the perovskite. The structure, developed in our lab, presents over 10% efficiency, and is also capable of performing as a highly efficient LED achieving over 22% EQE. Mesoporous Indium tin oxide (ITO) functions here as the back contact. The mesoscopic stack creates a scaffold for the perovskite solution to percolate and crystalize inside it. Screen printing is a simple and affordable fabrication method, common in the industry and suitable for large-scale production. In our recent projects, we are focusing on achieving high-efficiency ITO-PSCs, and developing this structure as an all inorganic printable LED as well.
