“…According to the working principle of KPFM, [ 27 ] it detects the potential difference between the sample surface and probe tip. The relative surface potential of a sample to the probe is represented by the voltage of V CPD applied to the tip to nullify the contact potential difference (CPD) [ 28 ] (see Figure S10 for details in the Supporting Information, and all the original V CPD results obtained below can be found in Sections S8–S10 in the Supporting Information). The probe is driven by an AC voltage in a lift mode at a lift height of 100 nm, and the scanning area is 2 × 2 µm 2 .…”

In this paper, new strategies are proposed to design high-performance organic-inorganic hybrid perovskite (PVK)-based triboelectric nanogenerators (TENGs) via both chemical composition modulation and electric field-induced ion migration in the films. Both composition variation and ion migration under electric field are found to change the type of conductivity of the perovskite films, then modify their surface potentials and electron affinities. These are utilized to fabricate PVK-based TENGs in pairs with poly-tetrafluoroethylene (PTFE) or nylon films, respectively. Results show that PVK films are able to work as either a positive or a negative tribo-material depending on the tribo-material pair used; the optimal performances are obtained for PTFE/ PVK TENGs using a PVK film with a MAI/PbI 2 ratio of 2 and forward polarization, and for nylon/PVK TENGs using a PVK film with a MAI/PbI 2 ratio of 0.4 and reverse polarization, respectively. The maximum output voltage and peak power density of PTFE/PVK TENGs are about 979 V and 24 W m −2 , 2.5 and 6.5 times higher than those of TENGs with nonoptimal composition ratio or that are poorly polarized. This work provides a new material design method for high-performance TENGs and a novel polarization strategy for TENG performance enhancement.

“…Based on this, Feng et al (2018) came up with an innovative TENG based on biodegradable leaf and leaf powder, which gives 15 µA current and 430 V under 5 Hz contact mode [96]. In the same device, poly-L-lysine (PLL) is applied to modify the leaf powder, which enhances the output performance as high as 60 µA and 1000 V. A conductive double-sided carbon tape composed of carbon powder was proposed as electrodes for TENGs by Shi et al [110] in 2018 for higher output power density. PDMS and polyamide 6 were used as a tribo-frictional layer, owing to a strong interaction between the carbon electrode, and the tribo-layer demonstrates a peak output voltage of ~1760 V, short circuit current of ~240 mA/m 2 , and power density of ~120 W/m 2 .…”

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.

“…Meanwhile, it is well known that the C of the dielectric materials increases as the interfacial area between dielectric materials and electrode increases because the surplus area acts as an additional capacitor [33,34]. On the basis of the advantageous effect of increased interfacial area, a new strategy to boost energy output of a TENG was recently reported as utilizing coarse carbon tape as the electrode [35]. However, in previous work, Al was utilized as the electrode of the control TENG group, which means the variable control of the electrode material is improperly achieved.…”

Given the operation conditions wherein mechanical wear is inevitable, modifying bulk properties of the dielectric layer of a triboelectric nanogenerator (TENG) has been highlighted to boost its energy output. However, several concerns still remain in regards to the modification due to high-cost materials and cumbersome processes being required. Herein, we report TENG with a microstructured Al electrode (TENG_ME) as a new approach to modifying bulk properties of the dielectric layer. The microstructured Al electrode is utilized as a component of TENG to increase the interfacial area between the dielectric layer and electrode. Compared to the TENG with a flat Al electrode (TENG_F), the capacitance of TENG_ME is about 1.15 times higher than that of TENG_F, and the corresponding energy outputs of a TENG_ME are 117 μA and 71 V, each of which is over 1.2 times higher than that of the TENG_F. The robustness of TENG_ME is also confirmed in the measurement of energy outputs changing after sandpaper abrasion tests, repetitive contact, and separation (more than 105 cycles). The results imply that the robustness and long-lasting performance of the TENG_ME could be enough to apply in reliable auxiliary power sources for electronic devices.
