“…The efficiency of solar cell could be enhanced by increasing the transmittance of TENG and fabricating particular nano-structures, which will reduce the reflection loss of light on the surface and thus improve the PCE of solar cell. [36,39] Meanwhile, it should be emphasized that the superhydrophobic surface of the TENG will prevent dust from staying on the surface and always provide a clean surface, ensuring the standard conversion efficiency of the solar cell. The spectral response of PSCs was characterized using external quantum efficiencies (EQEs) (Figure 5f).…”

The triboelectric nanogenerator (TENG) is an emerging technology that offers excellent potential for the conversion of mechanical energy from rain into electricity for hybrid energy applications. However, a high‐performance TENG is yet to be achieved because a quantitative analysis method for the energy conversion process is still lacking. Herein, a quantitative analysis method, termed the "kinetic energy calculation and current integration" (KECCI) method, which significantly improves the understanding of the mechanical‐to‐electrical energy conversion process, is presented. Based on the KECCI method, a high‐performance TENG is developed by systematically optimizing a biomimetic surface structure and instant switch design, with 1.25 mA short‐circuit current (Isc), 150 V open‐circuit voltage (Voc), and a high energy‐conversion efficiency of 24.89%. Furthermore, a multilayered TENG device is proposed for continuously harvesting the kinetic energy of raindrops for further improvement in the energy‐conversion efficiency. Finally, the multilayered TENGs are integrated with organic photovoltaics, achieving all‐weather energy harvesting. This work presents a validated theoretical basis that will guide further development of TENGs toward higher performances, which will promote the commercialization of hybrid TENG systems for all‐weather applications.

“…Similarly, Yoo et al prepared a moth's eye mimicking TENG on the solar cell to reduce the side effect from the triboelectric layer by its excellent specular transmittance [172]. Additionally, Zhao et al demonstrated a TENG/Si tandem hybrid solar cell by stacking Ag/PDMS electrode with a Si-based solar cell, in which both photovoltaic and triboelectric performances were enhanced by increased light transmittance and build-in electric field [173]. As a result, this tandem hybrid solar cell obtained a higher power conversion efficiency of 22.04% than the pristine solar cell.…”

This paper reports the performance of the flexible nanogenerator as a green energy harvester depends on connection variation. The ZnO nanogenerator was successfully fabricated on Al/PET. The ZnO Nanorods were synthesized using a hydrothermal method at 95°C. The ZnO Nanorods were characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transforms infrared spectroscopy (FTIR), and UV-Vis spectrophotometer. The performance of the nanogenerator was performed using Osiloscop and electrometer in series and parallel connection. Based on the XRD pattern, ZnO sample has a hexagonal (wurtzite) crystal structure in which the lattice parameters of a = b, and c = 3.258 Å, and 5.218 Å, respectively. The morphology of ZnO is a hexagonal form with diameters of 81,06 nm to 467.69 nm and rod length around 595 nm to 1331 nm. Based on the FTIR spectra, there are Zn-O bonds at 435-445 cm-1, 535 cm–1 and, 541 cm-1. Moreover, ZnO nanorods have an energy gap band of 3.2 eV. The performance of the ZnO nanogenerator in series form has the highest voltage with a value of 10.36 volts AC, and the voltage value in dual-source is more than ten times larger compared to a single source.
