Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

Abstract

The employment of cost-effective and durable structures is essential for the successful commercialization of perovskite solar cells (PSCs). Identifying a viable substitute for hole-selective materials (HSMs), which represent a significant expense in the production of PSCs, could provide a number of benefits. Carbon nanotube-based PSCs have shown promising potential as an alternative to conventional PSCs due to their unique properties such as excellent stability behavior to be potential for commercialization to produce green energy for human industries. One of the most crucial disadvantages of carbon derivatives as HSMs in CPSCs is their low hole mobility, which in the current study has been targeted. In the current study, to increase the efficiency of CPSCs, net carbon nanotubes (CNTs) were doped with nonmetallic fluorine via a facile synthesis method. It was found that introducing fluorine-doped CNTs (F-CNTs) as HSM for MAPbI3 perovskite could reach up to an efficiency of 15.29%, higher than the efficiency of 13.70% in devices with a net CNT layer. By doping CNTs with fluorine, the charge-transfer resistance and series resistance are reduced, resulting in lower charge recombination at the perovskite/CNT interface Also, the CPSCs with F-CNT film were more stable in ambient air because the F-CNTs covered more of the perovskite layer. The future trend of CNT-based PSCs is expected to focus on improving their performance, and exploring their potential for various optoelectronics.
