Abstract
Hybrid organic–inorganic materials that adopt perovskite-like architectures show intriguing order–disorder phase transitions and exciting electronic properties. We extend the classical concept of ionic tolerance factors to this important class of materials and predict the existence of several hitherto undiscovered hybrid perovskite phases.

Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performance

TL;DR: This work shows that the small and oxidation-stable rubidium cation (Rb+) can be embedded into a “cation cascade” to create perovskite materials with excellent material properties and achieved stabilized efficiencies of up to 21.6% on small areas.

Organic–Inorganic Perovskites: Structural Versatility for Functional Materials Design

TL;DR: This review will explore beyond the current focus on three-dimensional (3-D) lead(II) halide perovskites, to highlight the great chemical flexibility and outstanding potential of the broader class of 3-D and lower dimensional organic-based perovSKite family for electronic, optical, and energy-based applications as well as fundamental research.

Stabilizing Perovskite Structures by Tuning Tolerance Factor: Formation of Formamidinium and Cesium Lead Iodide Solid-State Alloys

TL;DR: In this article, the effect of alloying FA0.85Cs0.15PbI3 with CsPbIsI3 was investigated, and it was shown that the effective tolerance factor can be tuned and the stability of the photoactive α-phase of the mixed solid-state perovskite alloys FA1-xCsxPbisI3 is enhanced.

Organic–inorganic hybrid lead halide perovskites for optoelectronic and electronic applications

TL;DR: Recent progress on hybrid perovskites is reviewed including basic chemical and crystal structures, chemical synthesis of bulk/nanocrystals and thin films with their chemical and physical properties, device configurations, operation principles for various optoelectronic applications (with a focus on solar cells), and photophysics of charge-carrier dynamics.

Perovskite Materials for Light-Emitting Diodes and Lasers.

TL;DR: Although perovskite light-emitting devices are yet to become industrially relevant, in merely two years these devices have achieved the brightness and efficiencies that organic light-EMitting diodes accomplished in two decades.

Revised effective ionic radii and systematic studies of interatomic distances in halides and chalcogenides

TL;DR: The effective ionic radii of Shannon & Prewitt [Acta Cryst. (1969), B25, 925-945] are revised to include more unusual oxidation states and coordinations as mentioned in this paper.

Organometal Halide Perovskites as Visible-Light Sensitizers for Photovoltaic Cells

TL;DR: Two organolead halide perovskite nanocrystals were found to efficiently sensitize TiO(2) for visible-light conversion in photoelectrochemical cells, which exhibit strong band-gap absorptions as semiconductors.
