“…For TENGs to be effectively used as an ocean energy harvester, in addition to the requirements of the conventional TENG, such as high performance and lightweight, the following conditions are required:, (i) harvesting capability against multifrequency excitation, including low-frequency excitation, which is a property of ocean waves; (ii) waterproof or fully packaged devices to prevent performance degradation due to corrosion or decomposition under water; , (iii) extreme mechanical robustness so that it last for decades; and (iv) low-cost, large-area, and mass-producible fabrication processes to construct a harvester network with multiple TENGs in the ocean for commercialization. Recently, TENGs for ocean energy harvesting satisfying these conditions have been actively studied, particularly to improve harvesting efficiency because of their low energy conversion rate and low power output, as well as their utilization in ocean monitoring systems. − ,, In this section, we briefly summarize recent research on ocean-harvesting TENGs in relation to the issues mentioned earlier and discuss associated challenges and future research directions.…”

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade.

Luminescent solar concentrators (LSCs) are semitransparent windows that are able to generate electricity from sunlight absorption. LSCs have shown huge promise for realizing building-integrated photovoltaics (BIPV). Unfortunately, to date, the power conversion efficiency (PCE) of LSCs is still very low which dramatically hampers their practical applications. In this Perspective, We summarize and review the latest developments of LSCs by looking at different structures. Among others, we focus more on the next developments in the field of LSCs, i.e., the possibility of high PCE, large area, mass production, and durability needed for future industrial development. We hope to promote the application of uniform testing standards and to draw attention to industrial development, toxicity, and durability. Then, we will provide a critical assessment of the field of LSCs. Finally, the challenge and solution will be discussed.

“…With the rapid development of economy and technology, the sustainable development of human society has an increasing energy demand. A large amount of renewable clean energy is stored in natural water in the form of droplets, [1][2][3][4] waves, [5][6][7][8][9][10] flows, [11][12][13][14] and others. [15][16][17][18] Considering that most of these energy sources have the characteristics of low frequency, wide distribution and irregularity, it is not easy to use traditional electromagnetic power generation equipment to collect and utilize them.…”

Solid‐liquid triboelectric nanogenerators (SL‐TENGs) are a new technology that combines contact electrification (CE) and electrostatic induction to collect clean energy stored in natural water. Considering their unique advantages of high energy density, wide selection of materials and being suitable for large‐scale promotion, they have attracted more and more attention in recent years, and numerous studies have shown their great potential in various applications. Many critical applications of SL‐TENGs inevitably involve sustained and stable high electrical output. To achieve stable output performance and long cycle life in these applications, the adaptability of SL‐TENGs to material selection, structural design, and working environment is necessary. Therefore, the construction of SL‐TENGs matching different applications has become a critical research direction in TENGs. This review provides a historical summary of the development of SL‐TENGs in the past few years and analyzes the key factors affecting their electrical output performance. The exciting achievements of different constructions of SL‐TENGs for practical applications is also demonstrated such as energy harvesting, self‐powered sensing, and self‐powered cathodic protection. Finally, the development prospects of SL‐TENGs and the significant challenges for their further development is discussed.
