“…Among current portable powers, the flexible film solar cells (FFSCs) are a promising type power source due to their excellent portability, sustainable output, autogenic transformation and remarkable conversion efficiency [10][11][12][13][14]. The FFSCs, such as flexible amorphous silicon (α-Si, 13.6% [15]), flexible copper indium gallium selenide (CIGS, 21.7% [16]), flexible cadmium telluride (CdTe, 16.5% [17]), flexible gallium arsenide (GaAs, 26.7% [18]), flexible perovskite solar cells (PSC, 17.3% [19]) and flexible dye-sensitized solar cells (FDSSCs), all have been investigated widely and achieved remarkable conversion efficiency.…”

With growing demand for economic, eco-friendly, easy-manufacturing and renewable portable power source, flexible dye-sensitized solar cells (FDSSCs) exhibit a promising potential in the field of portable power sources. However, FDSSCs surfer from low conversion efficiency and poor stability, which hinder their applications. In this work, we have summarized recent development and challenges according to respective functions of their vital components (substrate, semiconductor film, sensitizer, electrolytes and counter electrode) as well as their effects on photoelectric conversion efficiency. Meanwhile, typical fabrication approaches have been analyzed for increasing the incident photon to current efficiency (IPCE). The approaches in rigid dye-sensitized solar cells (DSSCs) for improving performance are also introduced to provide the favorable direction for accelerating FDSSCs' application in field of potable power source.

“…The same behavior is also observed for conventional perovskite thin films [166][167][168] and chalcogenide thin films. [169][170][171] Poor adhesion of the TCO on these substrates, low barrier properties and chemical stability compared with typical glasses, and the restricted working temperature for the solar cell assembly, principally, are some key reasons that make polymer-based flexible solar cells generally less efficient than the ones constructed on rigid glasses. [166,172] Particularly, the PQD technology can contribute to solve this latter problem.…”

Perovskite quantum dots (PQDs) have revolutionized the field of perovskite solar cells in recent years. Using PQDs improves the operational stability of these devices, which is one of their main drawbacks for applications. This factor has motivated an intense search for new advances, from a fundamental aspect to improved performance in devices. Therefore, the developments obtained for PQD solar cells are discussed, presenting the challenges already overcome and the upcoming tendencies for research. Thus, the fundamental aspects of halide perovskite structures are first introduced. The advantages of their preparation as quantum dots are presented as well. The advances for post‐treatments (purification, passivation, and ligand exchange) are then discussed. Next, an in‐depth discussion of the PQD solar cell architectures is made, highlighting both the obsolete configurations and upcoming tendencies. A more specific view of the PQD compositions is then made, including lead‐free compositions and strategies for ionic substitution. Links of the photovoltaic performance are constructed with the devices’ architecture, post‐treatments, and perovskite composition, providing a wide‐ranging overview of these parameters for the devices’ efficiencies. Finally, the authors’ point of view about the future of PQD solar cell technology is presented, showing the main drawbacks, advantages, and opportunities for research.

“…In addition to advantages such as manufacturing accuracy, controllability, and high power of laser beam, laser scribing provides more other benefits than mechanical scribing to produce CIGS cells. The loss of power generation that occurs by the mechanical scribing method is reduced using laser scribing; so, an increase in solar cell efficiency is achieved [9], [10]. This occurs since layers between deposition processes are removed by the laser and monolithic cell-to-cell interconnections are created, resulting in minimal productive area loss [11].…”

Laser scribing is developing rapidly in industrial applications as a method of material processing, especially in areas that require high levels of precision. This technology provides functionality and efficiency improvements in the manufacturing of solar panels. Due to the premium quality and speed requirements of the laser scribing technology, monitoring of this process in real-time is critical in order to promptly detect defects in the manufacturing process. However, common monitoring systems have been developed for other laser processes, like laser welding, which are noticeably slower than the laser scribing process. The goal of this research was to investigate the possibility of using photodiodes for real-time monitoring of the laser scribing process for Copper Indium Gallium Selenide (CIGS) solar panels. Various monitoring setup configurations were designed, developed, and examined to determine the viable option for implementation as a defect detection platform. Using different photodiode positions, the intensity of the light and the photodiode induced voltage for diffuse and specular reflections were tested, and the practical pros and cons of applying each configuration were analyzed. The capability of the monitoring system to distinct the different layers of the scribed CIGS cell was also examined to assess the penetration depth of the scribe. In addition, by performing several experiments with different scribe thicknesses and analyzing oscilloscope measurements, the optimal placement of the photodiode for accurate tracing of the scribing path was determined and verified. Key aspects of development of such monitoring system for solar panel applications were identified through this research.
