Low-dimensional perovskite such as layered halide perovskite and perovskite nanocrystals have attracted attention in the past decade. These materials have impressive optoelectronic properties such as high photoluminescence and improved stability relative t ...

Infrared light management is crucial to maximize the optical performance of crystalline Si-based single junction and tandem solar cells. For this end, a low refractive index dielectric is typically inserted under the rear metal and an electrical contact is ...

In this work, we introduce a p-NiO/LiNiO stack grown via low-temperature deposition processes, offering an effective alternative for creating localized p-type regions in GaN devices. This stack combines a high hole concentration p-NiO film ([h] = 2 × 1019 ...

The central aim of this thesis is to investigate single molecule phenomena in self-assembled plasmonic nanocavities, focusing on achieving single molecule sensitivity within these highly confined electromagnetic environments. While self-assembled nanocavit ...

Carbonyl-containing materials employed in state-of-the-art hybrid lead halide perovskite solar cells (PSCs) exhibit a strong structure-dependent electron donor effect that predominates in defect passivation. However, the impact of the molecular spatial con ...

Perovskite-silicon (Si) tandem solar cells are the most prominent contenders to succeed single-junction Si cells that dominate the market today. Yet, to justify the added cost of inserting a perovskite cell on top of Si, these devices should first exhibit ...

Identifying sources of nonradiative recombination and quantifying charge carrier extraction in halide perovskite solar cells are important in further developing this thin-film technology. Steady-state and time-resolved photoluminescence (TRPL), in combinat ...

Zinc is the most abundant and broadly studied metal oxide semiconductor. Its photophysical properties include optical, electrical, magnetic, catalytic, sensing, energy storage, antibacterial, anti-oxidant, and drug delivery applications have been extensive ...

Chemical environment and precursor-coordinating molecular interactions within a perovskite precursor solution can lead to important implications in structural defects and crystallization kinetics of a perovskite film. Thus, the opto-electronic quality of s ...

CONSPECTUS: Two-dimensional (2D) semiconducting materials are poised to revolutionize ultrathin, high-performance optoelectronic devices. In particular, transition-metal dichalcogenides (TMDs) are well-suited for applications requiring robust and stable ma ...

Photocapacitor integrating both energy harvest and storage functions into a single device is a frontier research orientation, which facilitates the efficient and sustainable utilization of green energy. However, the multi-functions in one device and struct ...

Ion-selective electrodes (ISEs) represent one of the main technologies for developing sensors to measure ions concentration in human tissues. All-solid-state ISEs are of key importance for sensor miniaturization, especially toward point-of-care application ...

Historically, the field of plasmonics has been relying on the framework of classical electrodynamics, with the local-response approximation of material response being applied even when dealing with nanoscale metallic structures. However, when the confineme ...

Accurate forecasting of solar power generation with fine temporal and spatial resolution is vital for the operation of the power grid. However, state-of-the-art approaches that combine machinelearning with numerical weather predictions (NWP) have coarse re ...

Developing hole-transporting materials (HTMs) with appropriate molecular configuration and charge mobility is important to improve perovskite solar cell (PSC) photovoltaic performance and their feasibility for commercialization. In this work, a novel pyram ...

The emissive properties of two Ru(II) complexes, [Ru(dmbipy)(2)L-1]PF6 (1) and [Ru-2(dmbipy)(4)L-2]PF6 (2), (where L-1 and L-2 are pi-extended phenanthroline-based ligands and dmbipy = 4,4'-dimethyl-2,2'-bipyridine) have been explored for dual ap ...
