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,
