Resolving Nanoscale Heterogeneities in Lead Halide Perovskites Through Low‐Dose Concurrent 4D‐STEM‐EDX Mapping

Advanced Materials, EarlyView.
Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

Advanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

MATHEMATICAL MODELING, SIMULATION AND VALIDATION OF PHOTOVOLTAIC CELLS

International Journal of Research in Engineering and Technology, 2014
In this paper, an analysis has been done on the effect of varying physical and environmental factors on the I-V (current voltage characteristics) of a photovoltaic cell using Matlab-Simulink. A standalone model has been created based on the mathematical relations between various parameters in photovoltaic cells made up of a single diode, a series ...

Band Alignment and Composition of the Buried TiO2/GaInP Interface

Advanced Materials Interfaces, EarlyView.
Buried TiO2$\text{TiO}_2$/GaInP interfaces formed by mild plasma‐enhanced ALD are shown to be largely insensitive to the initial GaInP surface condition. Angle‐dependent photoelectron spectroscopy reveals similar interfacial chemistry and band alignment for phosphorus‐rich and naturally oxidized surfaces, demonstrating a robust pathway for reproducible
