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 ...
Tunable light emission by exciplex state formation between hybrid halide perovskite and core/shell quantum dots: Implications in advanced LEDs and photovoltaics
(American Association for the Advancement of Science, 2016)
We report the first observation of exciplex state electroluminescence due to carrier injection between the hybrid lead halide perovskite (MAPbI3–xClx) and quantum dots (core/shell PbS/CdS). Single layers of perovskite (PS) ...
Decoupling manufacturing from application in additive manufactured antimicrobial materials
(Royal Society of Chemistry, 2021-05-11)
3D printable materials based on polymeric ionic liquids (PILs)
capable of controlling the synthesis and stabilisation of silver
nanoparticles (AgNPs) and their synergistic antimicrobial activity
are reported. 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
(Wiley, 2016-02)
Hybrid lead halide perovskites have reached very large solar to electricity power conversion efficiencies, in some cases exceeding 20%. The most extensively used perovskite-based solar cell configuration comprises CH3NH3PbI3 ...
Femtosecond-laser-irradiation-induced structural organization and crystallinity of Bi2WO6
(Nature Research, 2020)
Controlling the structural organization and crystallinity of functional oxides is key to enhancing
their performance in technological applications. In this work, we report a strong enhancement of
the structural organization ...
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 ...
Mechanisms of charge accumulation in the dark operation of perovskite solar cells
(Royal Society of Chemistry, 2016)
In this work, a new current peak at forward bias in the dark current–voltage curves has been identified
for standard mesoscopic perovskite solar cells. This characteristic peak appears only under some specific
conditions, ...
Amorphous Iron Oxyhydroxide Nanosheets: Synthesis, Li Storage, and Conversion Reaction Kinetics
(American Chemical Society, 2013)
We present a facile approach to synthesize amorphous iron oxyhydroxide nanosheet from the surfactant-assisted oxidation of iron sulfide nanosheet. The amorphous iron oxyhydroxide nanosheet is porous and has a high surface ...
Molecular Electronic Coupling Controls Charge Recombination Kinetics in Organic Solar Cells of Low Bandgap Diketopyrrolopyrrole, Carbazole, and Thiophene Polymers
(American Chemical Society, 2013)
Low-bandgap diketopyrrolopyrrole- and carbazole-based polymer bulk-heterojunction, solar cells exhibit much faster charge carrier recombination kinetics than that encountered for less-recombining poly(3-hexylthiophene). ...
