Abstract

Abstract: Perovskites have become promising candidates for triboelectric nanogenerators (TENGs) because of their excellent electrical and dielectric properties. Also, and the as-fabricated triboelectric-photoelectric coupled TENG based on those semiconductor characteristics can effectively enhance the device output performance. Herein, a low-toxic lead-free bismuth halide perovskite CsBi3 I10 (CBI) film was proposed as triboelectric material for the first time, and a photo-enhanced TENG was designed based on CBI owing to its broad absorption properties. The CBI based TENG exhibits the highest voltage of 158 V and current density of 45.5 mA m −2 in dark condition. Furthermore, under illumination, the triboelectric output of voltage and current are increased by about 21.7% and 15.8% respectively, and the power density of the device can reach up to 4.95 W m −2 . This work not only initiates a new route for applying lead-free perovskite in TENGs but also presents a hybrid TENG for simultaneously harvesting mechanical and light energy based on the triboelectric-photoelectric coupling effect. Graphical Abstract: In this work, a low-toxic lead-free CsBi3 I10 (CBI) perovskite was proposed firstly as a photoactive tribo-positive material to construct photo-induced TENGs. Impressively, the triboelectric output of voltage and current are increased by about 21.7% and 15.8% under AM 1.5 G illumination, which output power density can reach 4.95 W m −2 . The study proposes a new kind of lead-free perovskite material for TENGs which have good application prospects for hybrid energy harvesters and self-powered detectors based on triboelectric and photoelectric effects. ga1 Highlights: ● A lead-free bismuth halide perovskite CsBi3 I10 film was proposed as triboelectric layer for the first time. ● The CsBi3 I10 /PDMS TENG output voltage and current are increased by about 21.7% and 15.8% under illumination. ● This work initiates a new route for applying low-toxic perovskite in photo-enhanced TENGs.
