and power the building in the night. [12] Such a smart combination not only provides multifunctions, but also saves materials and footprint in modern buildings. Another example is the wireless operation devices such as unmanned aerial vehicles and implantable biosensors, which are required to be placed in remote area or hazardous condition. They are required to be self-charged/powered by converting other energy forms from natural sources (such as heat, solar, and wind) or human movements (via piezoelectric and triboelectric effects) into usable power sources. [16][17][18][19][20] Moreover, the harvested energy needs to be stored electrochemically for backup power. [21][22][23] In this context, multifunctional devices/materials with multiple roles are imperative for the development of future self-powered smart devices.Electrochemical energy storage (EES) system is one of the most important parts in integrated smart devices. [24][25][26][27][28][29][30][31][32][33] The current dominant EES systems include lithium-ion batteries (LIBs) and supercapacitors. [34][35][36][37] The former generally possess high energy density but with relatively low power density, [38][39][40] whereas the latter have the opposite advantage and are typically used for high-power area. [41][42][43][44][45][46] In general, current EES devices require external power source and intensive maintenance. This can be challenging in deserts or other uninhabited areas. In this regard, it becomes quite relevant to develop self-powered smart devices by integrating energy harvest and conversion and storage units. [47] Currently, considerable efforts are being devoted to fabricating integrated/joint systems to combine energy harvesting/ storage components. The harvesting component can capture the energy from surroundings and convert into usable energy to power electrical devices. [28,48,49] For example, Wang and coworkers fabricated a series of self-powered devices (electrochromic devices, water splitting systems, and sensors) driven by piezoelectric nanogenerators and triboelectric nanogenerators. [50][51][52][53][54] Such nanogenerators convert the small magnitude of mechanical energy in our living environment into electricity. In addition, solar cells have also been integrated into electrochromic devices to achieve self-powered operation and to maximize energy saving/utilization. [55,56] Along with multifunction, attentions are also being paid to miniaturized energy systems such as nanosized and fibershaped energy conversion/storage devices. [57][58][59][60][61] Though planar-structured devices have the advantage of simple process and cost effectiveness, they cannot be easily integrated with wearable equipment. Hence, developing new materials that are flexible and stretchable, transparent and conductive, or Multifunctional energy devices with various energy forms in different operation modes are under current research focus toward the new-generation smart and self-powered electronics. In this review, the recent progress made in developing integrated/jo...

“…In this section, we highlight the most important advances that have focused on the application of CNTs and their hybrids in the counter electrodes of DSSCs. It should be noted that just a brief overview of CNTs as a catalyst layer for DSSCs is provided here, as there are a number of excellent reviews available on this topic . Very recently, a fresh review that provides a comprehensive discussion of Pt‐free counter electrodes for DSSCs has been published by three leading experts in this research field …”

As one type of emerging photovoltaic cell, dye-sensitized solar cells (DSSCs) are an attractive potential source of renewable energy due to their eco-friendliness, ease of fabrication, and cost effectiveness. However, in DSSCs, the rarity and high cost of some electrode materials (transparent conducting oxide and platinum) and the inefficient performance caused by slow electron transport, poor light-harvesting efficiency, and significant charge recombination are critical issues. Recent research has shown that carbon nanotubes (CNTs) are promising candidates to overcome these issues due to their unique electrical, optical, chemical, physical, as well as catalytic properties. This article provides a comprehensive review of the research that has focused on the application of CNTs and their hybrids in transparent conducting electrodes (TCEs), in semiconducting layers, and in counter electrodes of DSSCs. At the end of this review, some important research directions for the future use of CNTs in DSSCs are also provided.
