“…improved the recombination properties of the intermediate layer by using MoOx/ZnO/poly[(9,9-bis(30-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)] (PFN), in which the PFN could increase the built-in potential and reduced the contact resistance in the tandem devices ( Kim et al., 2015 ). Recently, CQDs/DSSC tandem solar cells have also been developed and achieved a PCE of more than 12% ( Yuan et al., 2020 ), which was derived from the adjustment of dye and E g of CQDs ( Figure 8 I).…”

Summary Infrared PbS colloidal quantum dot (CQD)-based materials receive significant attention because of its unique properties. The PbS CQD ink that originates from ligand exchange of CQDs is highly potential for efficient and stable infrared CQD solar cells (CQDSCs) using low-temperature solution-phase processing. In this review, we present a comprehensive overview of CQD inks for the development of efficient infrared solar cells, which can effectively harvest the photons from the infrared wavelength region of the solar spectrum, including the importance of infrared absorbers for solar cells, the unique properties of CQDs, ligand-exchange determined CQD inks, and related photovoltaic performance of CQDSCs. Finally, we present a brief conclusion, and the possible challenges and opportunities of the CQD inks are discussed in-depth to further develop highly efficient and stable infrared solar cells.

“…It functions as a photon detector, responding directly to the photons of radiation, as opposed to thermal detectors [3,4]. The large Bohr radius of 18 nm of the material leads to the observation of quantum confinement effects, a desirable property in the field of Dye Sensitized Solar Cells (DSSC) [5]. By many years, there has been an increasing interest in the development of semiconductor gas sensors to their advantageous features such as low cost, high sensitivity, fast response/recovery time, and simplicity in device structure and circuitry [6,7].…”

Polycrystalline nanostructured PbS thin ﬁlms are deposited onto soda-lime glass substrates by the method of chemical bath deposition (CBD) at different duration of deposition time. The structure and surface morphology of the ﬁlms are characterized by X-ray diﬀraction (XRD) and field effect scanning electron microscopy (FE-SEM). XRD pattern exhibits polycrystalline structure with preferential orientation along (200) direction, parameters such as crystallite size, lattice constant, lattice-strain and dislocation density are calculated. The FE-SEM images show appearance of flower like structure on formation of PbS films which is indicative of suitability in gas sensing applications. Studies on optical properties carried out by UV-Vis spectroscopy measurements show bandgap in the range 1.65eV – 1.41eV. The photoluminescence spectra of the films exhibit two peaks centered at around 613 nm and 738 nm after excitation at 450 nm. Electrical studies from Hall measurements indicate the carrier concentration and mobility of the PbS samples corroborate the variations in the conductivity.

“…Furthermore, the device exhibited high stability for low-power applications [71]. Subsequently, various research groups have studied DSSCs for different dyes such as N719 [72], N3 [73], CW10 [74], Y1A1 [75], D205 [72], Y123 [72], TF-tBu-C3F7 [76], TY6 [31], SK6 [74], SK7 [77], D35:XY1 [21], XY1b:Y123 [78], L350 [79], MD5 [80], MD7 [80], MM-6/MM-3 [81], LI-130 [82], SK6+CW10 [74], and XY1 [83] for indoor applications. The chemical structures of some dyes are depicted in Figure 6 Wen et al fabricated and utilized a polyvinylidene-fluoride-based quasi-solid electrolyte for an N719-dye-based DSSC.…”

The Internet of things (IoT) has been rapidly growing in the past few years. IoT connects numerous devices, such as wireless sensors, actuators, and wearable devices, to optimize and monitor daily activities. Most of these devices require power in the microwatt range and operate indoors. To this end, a self-sustainable power source, such as a photovoltaic (PV) cell, which can harvest low-intensity indoor light, is appropriate. Recently, the development of highly efficient PV cells for indoor applications has attracted tremendous attention. Therefore, different types of PV materials, such as inorganic, dye-sensitized, organic, and perovskite materials, have been employed for harvesting low-intensity indoor light energy. Although considerable efforts have been made by researchers to develop low-cost, stable, and efficient PV cells for indoor applications, Extensive investigation is necessary to resolve some critical issues concerning PV cells, such as environmental stability, lifetime, large-area fabrication, mechanical flexibility, and production cost. To address these issues, a systematic review of these aspects will be highly useful to the research community. This study discusses the current status of the development of indoor PV cells based on previous reports. First, we have provided relevant background information. Then, we have described the different indoor light sources, and subsequently critically reviewed previous reports regarding indoor solar cells based on different active materials such as inorganic, dye-sensitized, organic, and perovskite. Finally, we have placed an attempt to provide insight into factors needed to further improve the feasibility of PV technology for indoor applications.
