Transfer of chirality from light to a Disperse Red 1 molecular glass surface
(Optical Society of America, 2017-08-30)
Chiral structures and materials interact with light in well-documented ways, but light can also interact with achiral materials to generate chirality by inscribing its asymmetric configuration on photoresponsive materials, ...
Towards amorphous solution-processed small-molecule photovoltaic cells by design
(Elsevier, 2017-07-05)
Organic photovoltaic cells incorporating a homogeneously blended amorphous active layer were fabricated using a novel glass-forming squarylium cyanine derivative (SQ-glass) as donor, and both a previously reported glass-forming ...
T-Shaped Indan-1,3-dione Derivatives as Promising Electron Donors for Bulk Heterojunction Small Molecule Solar Cell
(Elsevier, 2017-04-24)
We report on the photovoltaic performance of novel T-Shaped Indan-1,3-dione derivatives as donors in a solution processed bulk heterojunction solar cells. Small molecule bulk heterojunction solar cells of these molecules ...
Fabrication, Photoluminescence, and Electrical Measurements of Molybdenum DiSulphide Films and Heterostructures
Transition-metal dichalcogenides (TMDs) exhibit unique optical and electronic properties that make them highly appealing to the scientific community. Like graphene, they have strong in-plane bonds allowing for easy fabrication ...
Atmospheric Dependence of Fractoluminescence and Phononic Emissions in Inorganic Scintillator Fractures
Background signals in particle detectors can originate from several categories of sources, including radioactivity found in the detector or its housing and cosmic radiations. High energy physics relies heavily on the use ...
Efficiency enhancement of ternary blend organic photovoltaic cells with molecular glasses as guest acceptors
(Elsevier, 2017-11-06)
Previously reported glass-forming perylenediimide (PDI-glass) and diketopyrrolopyrrole (DPP-glass) acceptors were used as ternary components to modulate the morphology and electron transport properties of bulk heterojunctions ...
Searching for Evidence of Optical Rectification: Optically-Induced Nonlinear Photovoltage in a Capacitor Configuration
(Optical Society of America, 2018-12-12)
A current challenge in photonics is to design new versatile photodetectors based on optical rectification induced photo-voltage; these ones are more attractive than classical photodetectors because they do not rely on band ...
Fabrication of planar heterojunction CsPbBr2I perovskite solar cells using ZnO as an electron transport layer and improved solar energy conversion efficiency
(RSC, 2018-06-26)
Inorganic lead halide perovskite solar cells with mixed halides have achieved reasonable power conversion efficiency with the advantage of an enhanced stability. In this work, we report the fabrication of an all inorganic ...
The Dynamics of Quantum States of Light in Lossy Coupled-Cavity Systems
Nonclassical states of light possess unique properties such as squeezing, antibunching, and entanglement, which have led to various interesting applications in quantum computing, quantum teleportation, and quantum ...
Exploiting ultrafast optical pulses: probing excitonic properties of 2D materials and utilizing the Kerr effect for all-optical switching
Ultrafast optics technology involves the development and application of femtosecond optical pulses. The work presented in this thesis consists of two research objectives which exploit these aspects of ultrafast optics ...
