Charge transport layer dependent electronic band bending in perovskite solar cells and its correlation to device degradation
Junseop Byeon, Jutae Kim, Ji-Young Kim +4
Perovskite solar cells (PSCs) have shown remarkably improved power-conversion efficiency of around 25%. However, their working principle remains arguable and the stability issue ha…
Sparking mashups to form multifunctional alloy nanoparticles
Jicheng Feng, Dong Chen, Peter V. Pikhitsa +3
Synthesizing unconventional alloys remains challenging owing to seamless interactions between kinetics and thermodynamics. High entropy alloys (HEAs), for example, draw a fundament…
Highly durable crack sensor integrated with silicone rubber cantilever for measuring cardiac contractility in culture media
Dong-Su Kim, Yong Whan Choi, Yun-Jin Jeong +5
We propose a novel cantilever device integrated with a polydimethylsiloxane (PDMS)-encapsulated crack sensor that directly measures the cardiac contractility. The crack sensor was…
