In this study, a catechin (tea dye)-adsorbed cellulose paper-based triboelectric nanogenerator (TAC-TENG) is suggested as an alternative solution. The material employed is tea dust extract incorporated cellulose paper, which are inexpensive, readily available, and eco-friendly. Triboelectric nanogenerator is an electrical energy-harvesting technology, capable of harvesting any kind of low-frequency mechanical energy as an energy source for powering small electronic devices. The proposed TAC-TENG could directly power up 12 white LEDs and store up to 2.08 μJ with a 1 μF capacitor in 80 s. A better performance was displayed by the tea dye-adsorbed cellulose paper than the pristine one. Thus, the proposed TENG could become more relevant and may have a vivid impact in the nearest future.

Fluorine-substituted materials have been widely utilized to passivate surface defects and improve the photovoltaic performance and stability of PSCs. In this study, post-treatment of the methylamine-lead iodide (MAPbI<small>₃</small>) perovskite surface was performed using 4-fluoroaniline trifluoroacetate (P-F-PMATFA), and the surface defects of the perovskite were passivated <em>via</em> an F atom, which reduced the energy barrier between the perovskite film (PVK) and hole transport layer (HTL).

Further, P-F-PMATFA treated perovskite devices exhibited long-term stability, owing to the higher hydrophobicity of fluorinated materials.
