TL;DR: Analysis of photocurrent measurements indicates that the light-harvesting efficiencies of NT-based DSSCs were higher than those found for D SSCs incorporating NPs owing to stronger internal light-scattering effects.

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.

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.

TL;DR: Park et al. as discussed by the authors proposed a reproducible manufacturing method for perovskite solar cells, as well as routes to manage grain boundaries and interfacial charge transport to achieve long-term stability.

TL;DR: In this article, the authors study the carrier dynamics in planar methyl ammonium lead iodide perovskite films using broadband transient absorption spectroscopy and show that the sharp optical absorption onset is due to an exciton transition that is inhomogeneously broadened with a binding energy of 9'meV.
