“…These types of TENGs changes the traditional way of solar energy harvesting and provides a new vision for all weather solar photovoltaic technologies. High humidity and contamination-resistant triboelectric nanogenerators with superhydrophobic interface [185] can be sandwiched with solar PV cells so that the PV cell can be dust resistant. Significant improvements in the TENGs are illustrated in Table 5.…”

A sustainable power source to meet the needs of energy requirement is very much essential in modern society as the conventional sources are depleting. Bioenergy, hydropower, solar, and wind are some of the well-established renewable energy sources that help to attain the need for energy at mega to gigawatts power scale. Nanogenerators based on nano energy are the growing technology that facilitate self-powered systems, sensors, and flexible and portable electronics in the booming era of IoT (Internet of Things). The nanogenerators can harvest small-scale energy from the ambient nature and surroundings for efficient utilization. The nanogenerators were based on piezo, tribo, and pyroelectric effect, and the first of its kind was developed in the year 2006 by Wang et al. The invention of nanogenerators is a breakthrough in the field of ambient energy-harvesting techniques as they are lightweight, easily fabricated, sustainable, and care-free systems. In this paper, a comprehensive review on fundamentals, performance, recent developments, and application of nanogenerators in self-powered sensors, wind energy harvesting, blue energy harvesting, and its integration with solar photovoltaics are discussed. Finally, the outlook and challenges in the growth of this technology are also outlined.

Currently, the key challenge in triboelectric nanogenerators (TENGs) is how to efficiently enhance the surface charge density. Here, a new strategy is proposed to increase the surface charge density by comprehensively utilizing solar energy and tidal energy, and a bioinspired photoelectric-electromechanical integrated TENG (Pem-iTENG) is developed. This enhancement of output performance is greatly attributed to the accumulation of photoelectrons from photocatalysis and the triboelectric negative charges from contact electrification. Pem-iTENG shows a maximal open-circuit voltage of 124.2 V and a maximal short-circuit current density of 221.6 μA cm−2 under tidal wave and sunlight, an improvement by nearly a factor of 10 over that of reported TENGs based on solid-liquid contact electrification. More importantly, it exhibits a high energy conversion efficiency according to the evaluation method for solar cells. This work provides insights into development of high-performance TENGs by using different natural energy sources.

“…Figure 3b is the corresponding charge transferred during the whole process in Figure a that reaches up to 50.2 µC. Compared with previous drop energy harvesters, [ 6,28,29 ] the current or accumulated charge value of SDMS is at least one order of magnitude higher. Such a damping electric performance is attributed to the multiple drop‐bounce behavior of the water drop on the superhydrophobic surface of SDMS.…”

are heavy, bulky, and immovable and are generally situated near dams, coasts, or river banks. [3-5] Furthermore, generating electricity using a traditional electromagnetic apparatus is difficult under low water supply, such as rainwater or fog. [6] Therefore, a small, novel, and portable electromagnetic system that can harvest energy from tiny water drops can act as a water-electricity transducer; such a system is an alternative to traditional hydropower equipment. Bioinspired superhydrophobic materials have low surface energy and microor nano-scale surface roughness, [7-9] rendering their unique capability to manipulate water droplets. By carefully designing and controlling the superhydrophobic surfaces, water drops can pin, [10] roll, [11] separate, [12] jump, [13] and react [14] and, therefore, can possess a variety of
