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

open access: yesLight: 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,

Self-consistent model of unipolar transport in organic semiconductor diodes: accounting for a realistic density-of-states distribution

open access: yes, 2011
A self-consistent, mean-field model of charge-carrier injection and unipolar transport in an organic semiconductor diode is developed utilizing the effective transport energy concept and taking into account a realistic density-of-states distribution as ...

Sensing of explosive vapor by hybrid perovskites: Effect of dimensionality

open access: yesAPL 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

Doping of organic semiconductors [PDF]

open access: yesphysica status solidi (a), 2012
AbstractThe understanding and applications of organic semiconductors have shown remarkable progress in recent years. This material class has been developed from being a lab curiosity to the basis of first successful products as small organic LED (OLED) displays; other areas of application such as OLED lighting and organic photovoltaics are on the verge
