Micromachines (Basel). 2019 Sep 26;10(10). doi: 10.3390/mi10100648.

Organic-inorganic hybrid solar cells composed of p-type conducting polymer poly (3,4-ethylene-dioxythiophene): polystyrenesulfonate (PEDOT: PSS) and n-type silicon (Si) have gained considerable interest in recent years. From this viewpoint, we present an efficient hybrid solar cell based on PEDOT: PSS...

PMID: 34879651
ACS Appl Mater Interfaces. 2021 Dec 08; doi: 10.1021/acsami.1c20456. Epub 2021 Dec 08.

Thermoelectric-based sensors with multifunctional sensing properties that can recognize different stimulations in a self-powered environment by converting low-grade heat into electrical energy have attracted increasing attention. However, the current thermoelectric-based multifunctional sensors are faced with issues such as limited...

Hyperfluorescent polymers enabled by through-space charge transfer polystyrene sensitizers for high-efficiency and full-color electroluminescence.

Chemical science

Hu J, Wang Y, Li Q, Shao S, Wang L, Jing X, Wang F.
PMID: 34745539
Chem Sci. 2021 Sep 03;12(39):13083-13091. doi: 10.1039/d1sc04389g. eCollection 2021 Oct 13.

Fluorescent polymers are suffering from low electroluminescence efficiency because triplet excitons formed by electrical excitation are wasted through nonradiative pathways. Here we demonstrate the design of hyperfluorescent polymers by employing through-space charge transfer (TSCT) polystyrenes as sensitizers for triplet...

Side-chain polymers have the potential to be excellent dopant-free hole-transporting materials (HTMs) for perovskite solar cells (PSCs) because of their unique characteristics, such as tunable energy levels, high charge mobility, good solubility, and excellent film-forming ability. However, there has...
