“…As a renewable and green energy, solar energy is undoubtedly an alternative to resolve these energy issues. In recent years, PV cells, which are increasingly popular alternatives to traditional photodetectors, have been studied extensively in the field of OWC [108]- [113]. Apart from harvesting the energy through the direct current (DC) component of the light source, a PV cell can also convert AC signals superimposed on the light source back to electrical signals for signal detection.…”

“…In [111], 34.2-Mbit/s signals were received by using organic PV cells and a red laser over a 1-m air channel. In addition to using LEDs or lasers operating in visible-light band and silicon wafer-based PV cells for OWC [108]- [111], researchers also employed mature near-infrared laser sources and GaAs PV cells to implement efficient energy harvesting and high-speed FSO communication [113]. However, an essential prerequisite for realizing long distances and high speeds is strict alignment, which limits the use of conventional OWC for mobile underwater platforms.…”

Underwater wireless optical communication (UWOC) has attracted increasing interest in various underwater activities because of its order-of-magnitude higher bandwidth compared to acoustic and radio-frequency technologies. Testbeds and pre-aligned UWOC links were constructed for physical layer evaluation, which verified that UWOC systems can operate at tens of gigabits per second or close to a hundred meters of distance. This holds promise for realizing a globally connected Internet of Underwater Things (IoUT). However, due to the fundamental complexity of the ocean water environment, there are considerable practical challenges in establishing reliable UWOC links. Thus, in addition to providing an exhaustive overview of recent advances in UWOC, this paper addresses various underwater challenges and offers insights into the solutions for these challenges. In particular, oceanic turbulence, which induces scintillation and misalignment in underwater links, is one key factor in degrading UWOC performance. Novel solutions are proposed to ease the requirements on pointing, acquisition, and tracking (PAT) for establishing robustness in UWOC links. The solutions include light-scattering-based non-line-of-sight (NLOS) communication modality as well as PAT-relieving scintillating-fiber-based photoreceiver and large-photovoltaic cells as the optical signal detectors. Naturally, the dual-function photovoltaic-photodetector device readily offers a means of energy harvesting for powering up future IoUT sensors.

“…Moreover, it is expected to support large-scale deployments of low-power consuming devices by employing existing energy-efficient lighting infrastructures (i.e., light emitting diodes (LEDs)) as light sources for simultaneous illumination and high-speed wireless data transmission [3]. Driven by the rapid escalation of energy-saving requirements, solar cells with the dual functions of energy harvesting and data acquisition are appealing as alternatives to commonly used detectors (i.e., positive-intrinsic-negative diodes and avalanche photodiodes) [3][4][5][6][7][8][9][10][11]. They are widely recognized as the key components of future self-powered IoT devices such as wearables, smart homes, smart transportation systems, and long-term environmental monitoring equipment with millions of sensors [3].…”

Enhancing robustness and energy efficiency is critical in visible light communication (VLC) to support large-scale data traffic and connectivity of smart devices in the era of fifthgeneration networks. To this end, we demonstrate that amorphous silicon (a-Si) thin-film solar cells with a high light absorption coefficient are particularly useful for simultaneous robust signal detection and efficient energy harvesting under the condition of weak light in this study. Moreover, a first-generation prototype called AquaE-lite is developed that consists of an a-Si thin-film solar panel and receiver circuits, which can detect weak light as low as 1 µW/cm 2. Using AquaE-lite and a white-light laser, orthogonal frequency-division multiplexing signals with data rates of 1 Mb/s and 908.2 kb/s are achieved over a 20-m long-distance air channel and 2.4-m turbid outdoor pool water, respectively, under the condition of strong background light. The reliable VLC system based on energy-efficient a-Si thin-film solar cells opens a new pathway for future satellite-air-ground-ocean optical wireless communication to realize connectivity among millions of Internet of Things devices.

“…It also reports solar panel receiver can be used for both data reception and simultaneous energy harvesting. VLC signal is retrieved from the sunlight interference by subtracting V max and V min [11]. However, no dedicated experimental design to reduce the ambient light noise from fluorescent lamp and to retrieve back the original signal is reported.…”

In the recent years, optical wireless communication using light emitting diode (LED) has increased lot of interest among researchers popularly known as visible-light communication (VLC). In such VLC system, an optical sensor used in the receiver side converts the modulated light signal into electrical signal. Conventionally, photo-diode (PD) is used as an optical sensor to serve this purpose. Instead of photo-diode, solar panel can be used as an optical sensor as it has the advantages of large collection area, easier targeting of light from an optical source, requires no external power supply and it shuns the reqirement of trans-impedance amplifier (TIA). However, ambient light noise due to indirect sunlight and fluorescent light is a major concern that affects the performance of the communication system in an indoor environment. In this paper, a new design of VLC receiver to reduce ambient light noise using solar panels is proposed. Experimental results show that the proposed receiver is capable of reducing ambient light noise caused by indirect sunlight and fluorescent lamp in an indoor environment. The implemented VLC system is capable of operating at 5.78 kHz and transmission distance of 0.40m is achieved.
