Enhanced efficiency of printable mesoscopic perovskite solar cells using ionic liquid additives†

The crystallization mechanism of the perovskite crystals inside the mesopores of printable mesoscopic perovskite solar cells is demonstrated by in situ grazing-incidence X-ray diffraction. Ionic liquids can universally tune the crystallization process of different perovksites in the mesopores regradless of the precursor solvents, resulting in enhanced efficiency.

Automated summary

The study demonstrates the crystallization mechanism of perovskite crystals inside the mesopores of printable mesoscopic perovskite solar cells using in situ grazing-incidence X-ray diffraction. It shows that ionic liquids can universally tune the crystallization process of different perovskites in the mesopores regardless of the precursor solvents, resulting in enhanced efficiency.
