Organic photovoltaics for simultaneous energy harvesting and high-speed MIMO optical wireless communications

Light: Science & Applications, 2021
We show that organic photovoltaics (OPVs) are suitable for high-speed optical wireless data receivers that can also harvest power. In addition, these OPVs are of particular interest for indoor applications, as their bandgap is larger than that of silicon,

Ohmic Electron Injection into Organic Semiconductors by Solution‐Processed and Evaporated Organic Interlayers

Advanced Materials Interfaces, 2023
Efficient electron injection from an electrode into an organic semiconductor remains a problem to solve for efficient organic semiconductor devices. In this work, a general method is presented to form an ohmic electron contact by inserting a thin organic

Sensing of explosive vapor by hybrid perovskites: Effect of dimensionality

APL Materials, 2020
Lead halide perovskites are very promising materials for many optoelectronic devices. They are low cost, photostable, and strongly photoluminescent materials, but so far have been little studied for sensing. In this article, we explore hybrid perovskites

Ionic multiresonant thermally activated delayed fluorescence emitters for light emitting electrochemical cells

Beilstein Journal of Organic Chemistry, 2022
We designed and synthesized two new ionic thermally activated delayed fluorescent (TADF) emitters that are charged analogues of a known multiresonant TADF (MR-TADF) compound, DiKTa.

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

Advanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.
