Chemi-Structural Stabilization of Formamidinium Lead Iodide Perovskite by Using Embedded Quantum Dots
Sofia Masi,C. Echeverría-Arrondo,K. M. Muhammed Salim,Thi Tuyen Ngo,P. F. Mendez,P. F. Mendez,Eduardo López-Fraguas,Eduardo López-Fraguas,David F. Macias-Pinilla,Josep Planelles,Juan I. Climente,Iván Mora-Seró +11 more
TL;DR: In this paper, the perovskite structure of formamidinium lead iodide (FAPI) was stabilized by a blue shift of the band gap, which limits the maximum photoconversion efficiency.

Chemi-Structural Stabilization of Formamidinium Lead Iodide Perovskite by Using Embedded Quantum Dots for High-Performance Solar Cells
Sofia Masi,C. Echeverría-Arrondo,Muhammed Sk,Thi Tuyen Ngo,P. F. Mendez,Eduardo López-Fraguas,David F. Macias-Pinilla,Josep Planelles,Juan I. Climente,Iván Mora-Seró +9 more
TL;DR: In this paper, the use of colloidal quantum dots (QDs) as stabilizing agent for the FAPI perovskite black phase was proposed, which achieved state-of-the-art performance.

Engineering Sr-doping for enabling long-term stable FAPb1−xSrxI3 quantum dots with 100% photoluminescence quantum yield
Andrés F. Gualdrón-Reyes,David F. Macias-Pinilla,Sofia Masi,C. Echeverría-Arrondo,Said Agouram,Vicente Muñoz-Sanjosé,Jhonatan Rodriguez-Pereira,Jan M. Macak,Jan M. Macak,Iván Mora-Seró +9 more
TL;DR: In this paper, the optical, structural properties and chemical environment of FAPb1−xSrxI3 perovskites were analyzed to understand how the suitable/poor Pb substitution achieved through Sr-doping influences the photophysical properties of PQDs that may be potentially applicable in optoelectronics.
Journal ArticleDOI
Comparison between Trion and Exciton Electronic Properties in CdSe and PbS Nanoplatelets
TL;DR: In this paper, the authors analyzed how the presence of an additional charge in trions modifies the emission energy and oscillator strength as compared to neutral excitons and observed that both negative and positive trions are redshifted with respect to the exciton, and their emission energy increases with increasing dielectric mismatch between the platelet and its surroundings.
Journal ArticleDOI
Biexcitons in CdSe nanoplatelets: geometry, binding energy and radiative rate.
TL;DR: In this paper , a variational Quantum Monte Carlo model was proposed to evaluate the biexciton ground state properties in colloidal CdSe nanoplatelets. And the model was used to provide theoretical assessment on the ground-state properties of colloidal cdSe nanostructures.
