Multi-Stacked Photodetectors with Polymer:Nonfullerene Bulk Heterojunction Sensing Layers for Li-Fi Communications |
| 초록 |
Visible light communication (VLC) has been recently spotlighted because the VLC-based light fidelity (Li-Fi) technology can exploit common lightings (lamps) as a signaling means with a faster communication speed than conventional radio frequency based wireless fidelity (Wi-Fi) technology. In terms of detectors for the VLC-based Li-Fi systems, inorganic photodiodes have been typically used to receive visible light signals from LED lightings with controlled frequencies. Basically, inorganic photodiodes benefit high stability but their demerits include rigid shapes without reasonable bendability/flexibility and high temperature processes leading to the limited sizes of detectors. In this presentation, we demonstrate multi-stacked detectors based on organic photodiode cells with different optical transparency and their sensing characteristics upon programmed visible light signals. |
