详情介绍：

PTQ11 is a wide bandgap copolymer alternating electron withdrawing quinoxaline and electron donating thiophene units as the backbone. Comparing to the low cost polymer donor PTQ10, PTQ11 shows stronger molecular crystallization tendency and better hole transport capability.

With zero HOMO offset, Non-fullerene polymer solar cells (NF-PSCs) based on PTQ11:TPT10 active layer shows highly efficient exciton dissociation and hole transfer, showing highly efficient device performance achieving PCE of 16.32% with a higher VOC of 0.88 V, a large JSC of 24.79 mA cm−2, and a high FF of 74.8% with the following device structure.

Device structure: ITO (indium tin oxide)/ZnO/PTQ11−TPT10/MoO3/Ag [1]

Thickness (nm) VOC (V) JSC (mA cm-2) FF (%) PCE (%)
