Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

Advanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...

Two-loop HTL-resummed thermodynamics for N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory

Journal of High Energy Physics, 2020
We compute the two-loop hard-thermal-loop (HTL) resummed thermodynamic potential for N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills (SYM). Our final result is manifestly gauge-invariant and was renormalized using only simple vacuum energy, gluon mass,

Effects of oxygen on the Liquid Silicon Infiltration (LSI) process

Open Ceramics, 2023
The Liquid Silicon Infiltration (LSI) process has been in use for decades for the series production of components of various SiC materials as well as for environmental barrier coatings. However, high rejection rates and variations in quality still occur.

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...
