Carbyne, a linear sp-hybridized carbon allotrope, is synthetically inaccessible and its properties are extrapolated from those of defined oligomers. Here the authors analyze weak optical bands in two series of oligoynes and reassess the optical and f

Comparing the excited-state properties of a mixed-cation–mixed-halide perovskite to methylammonium lead iodide. The journal of chemical physics, 152(10), p. 104703. American Institute of Physics AIP 10.1063/1.5133021

Organic-inorganic perovskites are one of the most promising photovoltaic materials for the design of next generation solar cells. The lead-based perovskite prepared with methylammonium and iodide was the first in demonstrating high power conversion e

Publikováno v: ACS Energy Letters

Methylammonium lead bromide perovskite (MAPbBr3) has been widely investigated for applications in visible perovskite light-emitting diodes (LEDs). Fine-tuning of the morphology and of the crystal size, from the microscale down to the quantum confinem
