Stable decaphenylcyclopentasilane hole transport layers for double-stacked perovskite photovoltaic devices fabricated under ambient atmosphere

Chemistry of Inorganic Materials
Stable decaphenylcyclopentasilane (DPPS) hole transport layers were developed for guanidinium-, formamidinium-, or ethylammonium-added double-stacked CH3NH3PbI3 perovskite photovoltaic devices without using 2,2′,7,7′-tetrakis (N,N-di-p-methoxyphenylamino)

Preparation and Characteristics of MAPbBr3 Perovskite Quantum Dots on NiOx Film and Application for High Transparent Solar Cells

Micromachines, 2018
In this work, a MAPbBr3 quantum dot (QD-MAPbBr3) layer was prepared by a simple and rapid method. Octylammonium bromide (OABr) gives the MAPbBr3 better exciton binding energy, good surface morphology, and stability. To form a nanocrystalline thin film on

Lifetime Comparisons of Organic Light-Emitting Diodes Fabricated by Solution and Evaporation Processes

Micromachines, 2023
In this paper, a blue fluorescent organic light-emitting diode (OLED) with a 1 cm2 emitting area was fabricated by a solution process. The ITO/spin MADN:13% UBD-07/TPBi/Al was used as the basic structure in which to add a hole-injection layer PEDOT:PSS ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Hole dangling-bond capture cross-sections in a-Si:H [PDF]

, 2013
It is demonstrated that the occupation statistics for a Gaussian distribution of dangling bond states may account for the measured variation of hole mobility-lifetime values in hydrogenated amorphous silicon as the Fermi energy is systematically varied ...
