“…To the best of our knowledge, the output voltage is the highest value among all the reported halide‐perovskite‐based mechanical energy harvesters (a comparison among the state‐of‐art halide‐perovskite‐based mechanical energy harvesters is summarized in Tables S6 and S7, Supporting Information). [ 33,68,71–74 ] The transferred charge is around 30 nC at the initial stage, and it will gradually increase with time due to the charge accumulation, further confirming that LPPS‐NFCs have excellent charge trapping capacity. The power output of the LPPS‐NFC‐based TPENG devices was also investigated by varying the different load resistors.…”

Halide‐perovskite‐based mechanical energy harvesters display excellent electrical output due to their unique ferroelectricity and dielectricity. However, their high toxicity and moisture sensitivity impede their practical applications. Herein, a stretchable, breathable, and stable nanofiber composite (LPPS‐NFC) is fabricated through electrospinning of lead‐free perovskite/poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) and styrene–ethylene–butylene–styrene (SEBS). The Cs3Bi2Br9 perovskites serve as efficient electron acceptors and local nucleating agents for the crystallization of polymer chains, thereby enhancing the electron‐trapping capacity and polar crystalline phase in LPPS‐NFC. The excellent energy level matching between Cs3Bi2Br9 and PVDF‐HFP boosts the electron transfer efficiency and reduces the charge loss, thereby promoting the electron‐trapping process. Consequently, this LPPS‐NFC‐based energy harvester displays an excellent electrical output (400 V, 1.63 µA cm−2, and 2.34 W m−2), setting a record of the output voltage among halide‐perovskite‐based nanogenerators. The LPPS‐NFC also exhibits excellent stretchability, waterproofness, and breathability, enabling the fabrication of robust wearable devices that convert mechanical energy from different biomechanical motions into electrical power to drive common electronic devices. The LPPS‐NFC‐based energy harvesters also endure extreme mechanical deformations (washing, folding, and crumpling) without performance degradation, and maintain stable electrical output up to 5 months, demonstrating their promising potential for use as smart textiles and wearable power sources.

“…To verify the position of GFF in the existing triboelectric series, several tribo-materials with different tribo-polarity including PTFE, PET, PE, Cu, Paper, Al, glass, and hair were selected to pair with GFF in vertical contact-separation mode triboelectrification tests. [33,34] Operation details are provided in Note S2, Supporting Information. Figure 2f reveals that positive current signal is observed during the contact process when GFF is paired with PTFE, indicating that the electrons transfer from GFF into PTFE.…”

Single‐electrode triboelectric nanogenerators (SE‐TENGs) are versatile tools for energy harvesting with simple structures and great practicability. However, low output performance hinders SE‐TENGs in applications as portable power sources. Herein, a novel SE‐TENG that utilizes glass fiber fabric (GFF) as tribo‐materials, along with an inorganic ferroelectric film for the dielectric layer is proposed. The GFF is first shown to be a promising tribo‐material for its highly positive tribo‐polarity and unique chemical/mechanical/durable properties. Meanwhile, an inorganic dielectric film with high dielectric constant is introduced between the GFF and Al electrode for enhancing the charge trapping capability. Owing to the synergistic effect of optimized triboelectrification and dielectric properties, the specific designed SE‐TENG delivers an open‐circuit voltage of 1640 V and a short‐circuit current density of 59.05 mA m−2, which are superior to most reported SE‐TENGs. With a maximum instantaneous power of 11.30 mW, the device can light up 1350 light‐emitting diodes, charge a 47 µF capacitor into 10 V in 421 s, and power up a digital watch even without additional control circuits. This work provides new insights in designing high‐performance SE‐TENGs and facilitates their application in biomechanical energy harvesting and portable power sources.

“…Based on its unique dielectric properties, Tang's group conducted in-depth research and optimization on halide perovskites as friction materials. [22][23][24][25][26] For example, the A, B, and X positions are doped with halide ions, [22] alkaline earth ions, [23] and alkali metal ions [24] to adjust the energy level structure, dielectric properties, polarization properties, and lattice size. A diamond-shaped array structure of Co(OH)(CO 3 ) 0.5 /Pt/ CsPbIBr 2 [25] and a metal/perovskite Schottky junction [26] were constructed to improve the triboelectric charge density.…”

Direct‐current triboelectric nanogenerators (DC‐TENGs) can directly convert mechanical energy into direct current (DC) electrical energy, exhibiting wide applications in micro/nano power sources, etc. Herein, a rolling‐mode DC‐TENG based on the tribo‐photovoltaic effect is proposed, which verifies that the tribovoltaic effect can be achieved in DC‐TENGs with a rolling structure instead of a conventional sliding structure. Utilizing the all‐inorganic perovskite CsPbBr3, a multifunctional DC‐TENG with excellent performance, that is capable of collecting both mechanical and solar energy is produced by constructing a dynamic Al/CsPbBr3 Schottky junction. Under illumination by light, the output voltage and current density reach 3.69 V and 11.46 A m−2, respectively. Furthermore, the output current of the dynamic Al/CsPbBr3 junction under illumination is 4.7 times higher than that in dark conditions. Meanwhile, the device exhibits excellent stability and the output performance does not significantly degrade after more than 10 min of cycling. In addition, the DC‐TENG shows potential applications in temperature and humidity sensing and directly charging capacitors. This work not only realizes a multifunctional DC‐TENG for simultaneously harvesting mechanical and solar energy, but also provides a novel route to enhance the work stability through a rolling‐mode device structure, which is of great significance for accelerating the development and applications of high‐performance DC‐TENGs.
