Usage

Description

Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl], also known as TQ1, is an alternating copolymer based on an alkoxylated quinoxaline acceptor and a thiophene donor. It is a cost-effective medium band-gap polymer donor material used for high-performance polymer solar cells. This polymer can be easily dissolved in various solvents such as chloroform, toluene, xylene, THF, chlorobenzene, and dichlorobenzene.

Uses

Used in High-Efficiency Organic Solar Cells (OPVs):
Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] is used as a polymer donor material for high-performance polymer solar cells. It contributes to achieving over 7% device efficiency in OPV devices when combined with PTQ1 as the polymer donor, PC71BM as the acceptor, and 1-Chloronaphthalene as an additive. This high efficiency is attributed to the polymer chain order and morphological effects, which result in a power conversion efficiency (PCE) of 6.0%, an open circuit voltage (Voc) of 0.89 V, a short circuit current density (Jsc) of 10.5 mA/cm2, and a fill factor (FF) of 0.64.
