PbI 2 heterogeneous-cap-induced crystallization for an efficient CH 3 NH 3 PbI 3 layer in perovskite solar cells

PbI heterogeneous-cap-induced crystallization with a face-to-face configuration is proposed to obtain efficient CH NH PbI perovskite films during thermal annealing. The films with large-size and dominative (110)-oriented grains can effectively boost the photovoltaic performance of the perovskite sol...

Zusammenfassung:PbI heterogeneous-cap-induced crystallization with a face-to-face configuration is proposed to obtain efficient CH NH PbI perovskite films during thermal annealing. The films with large-size and dominative (110)-oriented grains can effectively boost the photovoltaic performance of the perovskite solar cells.
