Scalable eDIPS-based single-walled carbon nanotube films for conductive transparent electrodes in organic solar cells

This letter demonstrates the scalable enhanced direct-injection pyrolytic synthesis (eDIPS)-based, wet-processed single-walled carbon nanotube (SWCNT) films for high-performance organic solar cells (OSCs) using acid dopants. Thanks to the good conductivity and smooth interfacial morphology of the 60 wt% HNO3-doped eDIPS-based SWCNT film, a power conversion efficiency (PCE) of 1.78% was achieved in a P3HT:PCBM OSC. In addition, the 60 wt% HNO3-doped eDIPS-based SWCNT film indicated excellent compatibility with a record-high PCE of 4.93% was achieved in a PBTZT-stat-BDTT-8:PCBM OSC.

Automated summary

This study demonstrates the application of wet-processed SWCNT films prepared using scalable eDIPS technology in high-performance organic solar cells. The use of acid dopants improves the conductivity and interfacial morphology of the SWCNT films, resulting in enhanced PCE efficiency.
