| 9 | Triple-cation perovskite solar cells for visible light communications显示文摘Hybrid perovskite materials are widely researched due to their high absorptivity,inexpensive synthesis,and promise in photovoltaic devices.These materials are also of interest as highly sensitive photodetectors.In this study,their potential for use in visible light communication is explored in a configuration that allows for simultaneous energy and data harvesting.Using a triple-cation material and appropriate device design,a new record data rate for perovskite photodetectors of 56 Mbps and power conversion efficiencies above 20%under white LED illumination are achieved.With this device design,the−3 dB bandwidth is increased by minimizing the dominating time constant of the system.This correlation between the bandwidth and time constant is proved using measurements of time-resolved photoluminescence,transient photovoltage,and device resistance. | NATALIE AMICA RUI BIAN PAVLOS MANOUSIADIS LETHY KJAGADAMMA IMAN TAVAKKOLNIA HARALD HAAS GRAHAM ATURNBULL IFOR DWSAMUEL | 2020 | Photonics Research2020，8，8： | 1 |
| 10 | Organic photovoltaics for simultaneous energy harvesting and high-speed MIMO optical wireless communications显示文摘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,leading to better matching to the spectrum of artificial light.By selecting a suitable combination of a narrow bandgap donor polymer and a nonfullerene acceptor,stable OPVs are fabricated with a power conversion efficiency of 8.8%under 1 Sun and 14%under indoor lighting conditions.In an optical wireless communication experiment,a data rate of 363 Mb/s and a simultaneous harvested power of 10.9 mW are achieved in a 4-by-4 multipleinput multiple-output(MIMO)setup that consists of four laser diodes,each transmitting 56 mW optical power and four OPV cells on a single panel as receivers at a distance of 40 cm.This result is the highest reported data rate using OPVs as data receivers and energy harvesters.This finding may be relevant to future mobile communication applications because it enables enhanced wireless data communication performance while prolonging the battery life in a mobile device. | Iman Tavakkolnia Lethy K.Jagadamma Rui Bian Pavlos P.Manousiadis Stefan Videv Graham A.Turnbull Ifor D.W.Samuel Harald Haas | 2021 | Light(Science & Applications)2021，10，3： | 0 |
