Copper redox mediators have enabled open‐circuit voltages (VOC) of over 1.0 V in dye‐sensitized solar cells (DSCs) and have helped to establish DSCs as the most promising solar cell technology in low‐light conditions. The addition of additives such as 4‐tert‐butylpyridine (tBP) to these electrolytes has helped in achieving high solar cell performances. However, emerging evidence suggests that tBP coordinates to the Cu(II) species and limits the performance of these electrolytes. To date, the implications of this coordination are poorly understood. Here, the importance of Lewis base additives for the successful implementation of copper complexes as redox mediators in DSCs is demonstrated. Two redox couples, [Cu(dmp)2]+/2+ and [Cu(dpp)2]+/2+ (with dmp = 2,9‐dimethyl‐1,10‐phenanthroline and dpp = 2,9‐diphenyl‐1,10‐phenanthroline) in combination with three different Lewis bases, TFMP (4‐(trifluoromethyl)pyridine), tBP, and NMBI (1‐methyl‐benzimidazole), are considered. Through single‐crystal X‐ray diffraction analysis, absorption, and 1H‐NMR spectroscopies, the coordination of Lewis bases to the Cu(II) centers are studied. This coordination efficiently suppresses recombination losses and is crucial for high performing solar cells. If, however, the coordination involves a ligand exchange, as is the case for [Cu(dpp)2]+/2+, the redox mediator regeneration at the counter electrode is significantly retarded and the solar cells show current limitations.

The past few years have witnessed the significant impacts of wearable electronics/photonics on various aspects of our daily life, for example, healthcare monitoring and treatment, ambient monitoring, soft robotics, prosthetics, flexible display, communication, human‐machine interactions, and so on. According to the development in recent years, the next‐generation wearable electronics and photonics are advancing rapidly toward the era of artificial intelligence (AI) and internet of things (IoT), to achieve a higher level of comfort, convenience, connection, and intelligence. Herein, this review provides an opportune overview of the recent progress in wearable electronics, photonics, and systems, in terms of emerging materials, transducing mechanisms, structural configurations, applications, and their further integration with other technologies. First, development of general wearable electronics and photonics is summarized for the applications of physical sensing, chemical sensing, human‐machine interaction, display, communication, and so on. Then self‐sustainable wearable electronics/photonics and systems are discussed based on system integration with energy harvesting and storage technologies. Next, technology fusion of wearable systems and AI is reviewed, showing the emergence and rapid development of intelligent/smart systems. In the last section of this review, perspectives about the future development trends of the next‐generation wearable electronics/photonics are provided, that is, toward multifunctional, self‐sustainable, and intelligent wearable systems in the AI/IoT era.

Energy harvesting systems are used with or instead of batteries to provide energy to low power devices such as sensors and sensor nodes. The most commonly used energy harvesting systems are those that obtain electrical energy from vibration. Because vibrations can be found intensively in the environment. In this study, the systems that produce energy by means of various circuits attached around wires carrying electrical energy are examined. These are generally piezoelectric and electromagnetic energy harvester systems. In the studies, the effects of the distance, the magnitude of the current flowing through the wire and the load resistance to be connected to the energy harvester were investigated. In addition, permanent magnet arrays have been used to increase the amount of power to be obtained in some applications.
