Light Capacitances in Silicon and Perovskite Solar Cells
(Elsevier, 2019)
The framework on which the physics of silicon solar cells (SiSCs) is based robustly predicts
dependences of capacitance on light intensity and voltage, even when most recent innovations
are considered as the incorporation ...
Partial coverage methylammonium lead bromide films for solar cell application
(Elsevier, 2019-11-30)
Hybrid perovskite compounds as methylammonium lead halides are currently been
investigated for different optoelectronic applications. CH3NH3PbBr3 is a promising
member because of its electronic structure and large bandgap ...
Bidirectional frequency-shifting loop for dual-comb spectroscopy
(Optical Society of America, 2019)
We present a bidirectional recirculating frequency-shifting
loop, seeded by a continuous-wave (cw) laser, to perform
multi-heterodyne interferometry. This fiber-optic system
generates two counter-propagating “acousto-optic” ...
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 ...
Diffractive control of 3D multifilamentation in fused silica with micrometric resolution
(Optical Society of America, 2016)
We show that a simple diffractive phase element (DPE) can be used to manipulate at will the positions and energy of multiple filaments generated in fused silica under femtosecond pulsed illumination. The method allows ...
Synthesis and characterization of organic agar-based membranes for microbial fuel cells
(Elsevier, 2019-09-30)
The goal of this work was the synthesis and characterization of agar membranes for microbial fuel cells applications. Three sets of membranes were synthesized. For a first set of membranes (2, 4, 6, and 8 wt% agar ...
Ultrathin Acoustic Parity-Time Symmetric Metasurface Cloak
(American Association for the Advancement of Science, 2019)
Invisibility or unhearability cloaks have beenmade possible by using metamaterials enabling light or sound to flow around obstacle
without the trace of reflections or shadows. Metamaterials are known for being flexible ...
Potassium ions as a kinetic controller in ionic double layers for hysteresis-free perovskite solar cells
(Royal Society of Chemistry, 2019-07-22)
Since ion migration and interaction with external contacts has been regarded as one of the origins for photocurrent density (J)–voltage (V) hysteresis and phase segregation in perovskite solar cells (PSCs) under operational ...
Charge carrier transport and contact selectivity limit the operation of PTB7-based organic solar cells of varying active layer thickness
(Royal Society of Chemistry, 2013-08)
In this work we study the different electrical loss pathways occurring during the operation of bulk heterojunction solar cells by using a variety of electrical and optical characterization techniques beyond the current ...
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 ...
