Perovskite optoelectronics

---

Here, a synthetic strategy applied to a range of quasi-2D perovskite systems is reported, that significantly narrows the quantum well dispersion. This approach will serve in producing new materials widening the color gamut of next-generation displays.

Herein, we show that heating a SnO2 colloidal solution results in compact films with increased surface coverage. The improved surface coverage induces larger perovskite grains resulting in efficient and stable solar cells.

Here we report a fast and reproducible doping method that involves exposing conjugated organic molecules with carbon dioxide under ultraviolet light. This method greatly decreases fabrication time while increasing device stability.

Here, we report perovskite solar cells having exceptionally high fill factors of 85% and enhanced open-circuit voltage without sacrificing short-circuit current through a polymer-capped solvent-annealing process assisted by a hot air blower. Our results provide a pathway to increase the device efficiency and stability of perovskite solar cells.
