Overcoming ionic migration in perovskite solar cells through alkali metals
(Elsevier, 2024-01-17)
Alkali metals, as additives in perovskite solar cells (PSCs), have been extensively investigated for their impact on performance enhancement. This performance is sensitive to ion-driven interfacial recombination processes ...
Utilization of Temperature-Sweeping Capacitive Techniques to Evaluate Band Gap Defect Densities in Photovoltaic Perovskites
(American Chemical Society, 2019-06-12)
Capacitive techniques, routinely used for solar cell parameter extraction, probe the voltage-modulation of the depletion layer capacitance isothermally as well as under varying temperature. In addition, defect states within ...
Welcoming the First Decade of Perovskite Solar Cells
(Wiley, 2019-09-02)
The swift emergence of perovskite solar cells (PSCs) is a “miracle” development in the history of photovoltaics. Since Miyasaka and co‐workers (Toin University of Yokohama, Japan) reported the first use of halide perovskites ...
PbS quantum dots as additives in methylammonium halide perovskite solar cells: the effect of quantum dot capping
(Royal Society of Chemistry, 2019-09)
Colloidal PbS quantum dots (QDs) have been successfully employed as additives in halide perovskite solar cells (PSCs) acting as nucleation centers in the perovskite crystallization process. For this strategy, the surface ...
Single-Exciton Amplified Spontaneous Emission in Thin Films of CsPbX3 (X = Br, I) Perovskite Nanocrystals
(American Chemical Society, 2019-09-23)
CsPbX3 perovskite nanocrystals (PNCs) have emerged as an excellent material for stimulated emission purposes, with even more prospective applications than conventional colloidal quantum dots. However, a better understanding ...
Homeopathic Perovskite Solar Cells: Effect of Humidity during Fabrication on the Performance and Stability of the Device
(American Chemical Society, 2018-02)
Rapid degradation in humid environments is a major drawback of methylammonium lead iodide (CH3NH3PbI3), which is the archetypical component of perovskite solar cells. In this work, we have investigated the aging and ...
Effect of Environmental Humidity on the Electrical Properties of Lead Halide Perovskites
(ACS, 2018-12)
In large quantities, water is detrimental to lead halide perovskite solar cells, mainly because of the decomposition of the perovskite layer. In contrast, the presence of small quantities of water has been observed to play ...
Interpretation of the photoluminescence decay kinetics in metal halide perovskite nanocrystals and thin polycrystalline films
(Elsevier, 2020-05)
In this paper we present critical analysis of different points of view on interpretation of the photoluminescence (PL) decay kinetics in lead halide perovskites prepared in the form of well passivated nanocrystals (PNCs) ...
Enhanced nanoscopy of individual CsPbBr3 perovskite nanocrystals using dielectric sub-micrometric antennas
(AIP Publishing, 2020-02-11)
We demonstrate an efficient, simple, and low-cost approach for enhanced nanoscopy in individual green emitting perovskite (CsPbBr3)nanocrystals via TiO2dielectric nanoantenna. The observed three- to five-fold ...
Suppressing the Formation of High n-Phase and 3D Perovskites in the Fabrication of Ruddlesden-Popper Perovskite Thin Films by Bulky Organic Cation Engineering
(American Chemical Society, 2022-02-24)
Two-dimensional perovskites (2D PVKs) were first studied because of their dielectric and magnetic properties for dielectric and transistor applications in the electronic field. As the optical properties were elucidated ...
