Carrier recombination flux in bulk heterojunction polymer: fullerene solar cells: Effect of energy disorder on ideality factor
(Elsevier, 2013-01)
Energy disorder reduces the achievable open-circuit voltage in organic bulk-heterojunction solar cells. Here the effect of disorder on charge carrier recombination flux is numerically modeled. The recombination current ...
Majorana-like Zero Modes in Kekulé Distorted Sonic Lattices
(American Physical Society, 2019)
Topological phases have recently been realized in bosonic systems. The associated boundary modes
between regions of distinct topology have been used to demonstrate robust waveguiding, protected from
defects by the topology ...
Analysis of the Hysteresis Behavior of Perovskite Solar Cells with Interfacial Fullerene Self-Assembled Monolayers
(American Chemical Society, 2016-10)
The use of self-assembled monolayers (SAMs) of fullerene derivatives reduces the hysteresis of perovskite solar cells (PSCs). We have investigated three different fullerene derivatives observing a decrease on hysteresis ...
In situ decoration of graphene sheets with gold nanoparticles synthetized by pulsed laser ablation in liquids

The demand for nanocomposites of graphene and carbonaceous materials decorated with metallic nanoparticles is increasing on account of their applications in science and technology. Traditionally, the production of ...
Overcoming the barrier of nanoparticle production by femtosecond laser ablation in liquids using simultaneous spatial and temporal focusing
(Optical Society of America, 2019)
There exists an increasing demand of industrial-scale production of high-purity ligand-free nanoparticles due to
the continuous development of biomedicine, catalysis, and energy applications. In this contribution, a ...
Balanced change in crystal unit cell volume and strain leads to stable halide perovskite with high guanidinium content
(Royal Society of Chemistry, 2022)
Up-to-date studies propose that strain in halide perovskites is one of the key factors that determine
a device's efficiency and stability. Here, we show a systematic approach to characterize the
phenomenon in the standard ...
Stochastic pumping of ions based on colored noise in bacterial channels under acidic stress
(Royal Society of Chemistry, 2016-06)
Fluctuation-driven ion transport can be obtained in bacterial channels with the aid of different types of colored noise including the biologically relevant Lorentzian one. Using the electrochemical rectification of the ...
Plasmon-enhanced photocurrent in quasi-solid-state dye-sensitized solar cells by the inclusion of gold/silica core–shell nanoparticles in a TiO2 photoanode
(Royal Society of Chemistry, 2013-09)
Direct evidence of the effects of the localized surface plasmon resonance (LSPR) of gold nanoparticles (Au NPs) in TiO2 photoanodes on the performance enhancement in quasi-solid-state dye-sensitized solar cells (DSCs) is ...
Ionic Reactivity at Contacts and Aging of Methylammonium Lead Triiodide Perovskite Solar Cells
