Graded bulk-heterojunction enables 17% binary organic solar cells via nonhalogenated open air coating

Ying Zhang et al.

Summary: The study demonstrates an effective graded bulk-heterojunction (G-BHJ) strategy using nonhalogenated solvent sequential deposition for nonfullerene acceptor (NFA) organic solar cells, achieving outstanding power conversion efficiency (PCE) of 17.48%. Advanced techniques such as depth-profiling X-ray photoelectron spectroscopy (DP-XPS) and angle-dependent grazing incidence X-ray diffraction (GI-XRD) enable visualization of morphology and crystallinity gradient distributions, leading to high PCEs of thick OSCs. The use of nonhalogenated solvent in G-BHJ OSC via open-air blade coating achieves a record 16.77% PCE by suppressing unfavorable phase separation in bulk-heterojunction. Overall, the G-BHJ strategy shows great promise for highly efficient, eco-friendly, and scalable organic solar cells.

Sustainable highly charged C-60-functionalized polyimide in a non-contact mode triboelectric nanogenerator

Jae Won Lee et al.

Summary: In this paper, a new dielectric material, a C-60-containing block polyimide (PI-b-C-60), was reported for use in a non-contact mode triboelectric nanogenerator (TENG). The TENG based on PI-b-C-60 achieved high output power and reliable operation, outperforming perfluoroalkoxy alkane film-based TENGs. The excellent charge-retention characteristics of PI-b-C-60, induced by the most negative electrostatic potential of C-60 within the backbone, were confirmed by surface potential measurements. Additionally, two non-contact mode applications, a keyless electronic door lock system and a speed sensor with a tone wheel for a car, were successfully developed during the study.
