“…In all the application contexts where no direct sunlight is available, good candidates for solar energy harvesting appear to be DSSCs. Indeed, some works have already proven their efficiency in these operating conditions [17][18][19]. For this reason, DSSCs may represent the best option as power sources for energy self-sufficient wireless data acquisition platforms.…”

This paper aims to demonstrate the viability of energy harvesting for wide area wireless sensing systems based on dye-sensitized solar cells (DSSCs) under diffuse sunlight conditions, proving the feasibility of deploying autonomous sensor nodes even under unfavorable outdoor scenarios, such as during cloudy days, in the proximity of tall buildings, among the trees in a forest and during winter days in general. A flexible thin-film module and a glass thin-film module, both featuring an area smaller than an A4 sheet of paper, were initially characterized in diffuse solar light. Afterward, the protype sensor nodes were tested in a laboratory in two different working conditions, emulating outdoor sunlight in unfavorable lighting and weather to reconstruct a worst-case scenario. A Li-Po battery was employed as a power reserve for a long-range wide area network (LoRaWAN)-based sensor node that transmitted data every 8 h and every hour. To this end, an RFM95x LoRa module was used, while the node energy management was attained by exploiting a nano-power boost charger buck converter integrated circuit conceived for the nano-power harvesting from the light source and the managing of the battery charge and protection. A positive charge balance was demonstrated by monitoring the battery trend along two series of 6 and 9 days, thus allowing us to affirm that the system’s permanent energy self-sufficiency was guaranteed even in the worst-case lighting and weather scenario.

“…Research of ALCs has been intently geared towards harvesting and recycling ambient light and thus has possibly enabled efficient energy use in our daily lives. [12][13][14][15][16][17] Although the spectral intensity, wavelength, and energy harnessed from commonly utilized household light sources are markedly different from those of the Sun (Figure 1a), drawing on this local energy source has become imperative and promising for providing reliable and sustainable off-grid power supplies in portable and wearable internet of things (IoT) applications, as shown in Figure 1b. Accordingly, integration of ALCs with several household devices has already been attempted, and as the demand for IoT application power supplies, the ALC market size and revenue are estimated to correspondingly surge.…”

Perovskites have encountered a growing interest as light‐absorbing materials for harvesting and recycling ambient light. This interest comes from the distinct and impressive intrinsic properties of these materials and is necessitated by the need for reliable and sustainable power supplies for wearable and portable internet of things (IoT) applications. Perovskite artificial light cells (PALCs; i. e., indoor perovskite photovoltaics) have been intensively explored, and thus their device performance has been rapidly augmented. In this review, we summarize and consolidate the research outputs of PALCs by focusing on the tuning of photo‐absorber and interlayer materials for efficient harvest and collection of artificial light sources. We also emphasize various challenges and possible future research directions that should be addressed for realizing a large market uptake of PALCs.

“…DSSCs belong to the group of thin-film solar cells. The working electrode, sensitizer (dye), redox-mediator (electrolyte), and the counter electrode are four key elements of a DSSC [27,28]. In DSSC, a photon is absorbed by a photosensitizer adsorbed on nano-TiO 2 (semiconductor), generating an exciton (excited electron-hole couple) that self-separates, and the electrons are injected into the conduction band of TiO 2 .…”

The dye-sensitized solar cells microfluidically integrated with a redox flow battery (µDSSC-RFB) belong to a new emerging class of green energy sources with an inherent opportunity for energy storage. The successful engineering of microfluidically linked systems is, however, a challenging subject, as the hydrodynamics of electrolyte flow influences the electron and species transport in the system in several ways. In the article, we have analyzed the microflows hydrodynamics by means of the lattice-Boltzmann method, using the algebraic solution of the Navier-Stokes equation for a duct flow and experimentally by the micro particle image velocimetry method. Several prototypes of µDSSC were prepared and tested under different flow conditions. The efficiency of serpentine µDSSC raised from 2.8% for stationary conditions to 3.1% for electrolyte flow above 20 mL/h, while the fill factor increased about 13% and open-circuit voltage from an initial 0.715 V to 0.745 V. Although the hexagonal or circular configurations are the straightforward extensions of standard photo chambers of solar cells, those configurations are hydrodynamically less predictable and unfavorable due to large velocity gradients. The serpentine channel configuration with silver fingers would allow for the scaling of the µDSSC-RFB systems to the industrial scale without loss of performance. Furthermore, the deterioration of cell performance over time can be inhibited by the periodic sensitizer regeneration, which is the inherent advantage of µDSSC.
