Layered Perovskites Enhanced Perovskite Photodiodes

The Journal of Physical Chemistry Letters, 2021
Recently, two-dimensional layered perovskites have emerged as effective additives for stabilizing conventional three-dimensional metal halide perovskites. With the addition of layered perovskites, the perovskite-based devices also exhibited enhanced optoelectronic properties, such as reduced nonradiative recombination and ionic migration, strengthened ...

Review of Interface Passivation of Perovskite Layer [PDF]

Nanomaterials, 2021
Perovskite solar cells (PSCs) are the most promising substitute for silicon-based solar cells. However, their power conversion efficiency and stability must be improved. The recombination probability of the photogenerated carriers at each interface in a PSC is much greater than that of the bulk phase.
