Tuning the Light Emission Properties by Band Gap Engineering in Hybrid Lead Halide Perovskite
Valerio D’Innocenzo,Valerio D’Innocenzo,Ajay Ram Srimath Kandada,Michele De Bastiani,Michele De Bastiani,Marina Gandini,Annamaria Petrozza +6 more
TL;DR: It is demonstrated that larger crystallites present smaller band gap and longer lifetime, which correlates to a smaller radiative bimolecular recombination coefficient, and also shows that they present a higher optical gain, becoming preferred candidates for the realization of CW lasing devices.

Methylammonium Bismuth Iodide as a Lead‐Free, Stable Hybrid Organic–Inorganic Solar Absorber
Robert L. Z. Hoye,Riley E. Brandt,Anna Osherov,Vladan Stevanović,Vladan Stevanović,Samuel D. Stranks,Samuel D. Stranks,Mark W. Wilson,Hyunho Kim,Austin Akey,John D. Perkins,Rachel C. Kurchin,Jeremy R. Poindexter,Evelyn N. Wang,Moungi G. Bawendi,Vladimir Bulovic,Tonio Buonassisi +16 more
TL;DR: Through MBI, this work demonstrates a lead-free and stable alternative to MAPbX3 that has a similar electronic structure and nanosecond lifetimes and found that MBI luminesces at room temperature, with the vapor-processed films exhibiting superior photoluminescence decay times that are promising for photovoltaic applications.
