Visible Light Communication technology has the potential to become a leading actor in the future 5G network, thanks to features such as efficient "re-use of re-sources", native privacy security and human safeness (compared to radio-frequency applications). Among the several configurations achievable to realize a VLC link, the use of innovative photovoltaic devices as receiver, based on organic-inorganic printable semiconductors (hybrid perovskite materials), has the potential to pave the way to new scenario applications, thanks to the inherent cheaper costs of fabrication via roll-to-roll solution-based processes, possibly on flexible substrates. In this context, we have fabricated photo-detectors with three different types of perovskite, and used with a commercial cool-white LED to realize a prototype of visible light communication data link. Using a single-stage transimpedance amplifier for the perovskite photodetector, we have reached a remarkable frequency bandwidth close to similar to 800 KHz.

Abstract
Visible Light Communication technology has the potential to become a leading actor in the future 5G network, thanks to features such as efficient "re-use of re-sources", native privacy security and human safeness (compared to radio-frequency applications). Among the several configurations achievable to realize a VLC link, the use of innovative photovoltaic devices as receiver, based on organic-inorganic printable semiconductors (hybrid perovskite materials), has the potential to pave the way to new scenario applications, thanks to the inherent cheaper costs of fabrication via roll-to-roll solution-based processes, possibly on flexible substrates. In this context, we have fabricated photo-detectors with three different types of perovskite, and used with a commercial cool-white LED to realize a prototype of visible light communication data link. Using a single-stage transimpedance amplifier for the perovskite photodetector, we have reached a remarkable frequency bandwidth close to similar to 800 KHz.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
