研究目的
Investigating the potential of tuning poly(9-vinylcarbazole) (PVK) properties through functionalization for an application as hole transport material (HTM) for perovskite solar cells (PSCs).
研究成果
The functionalization of PVK with bis(4-methoxyphenyl)amine moieties improved its hole mobility and HOMO level, leading to PSCs with a best PCE of 16.7%. The study demonstrates the potential of PVK-based polymers as HTMs in PSCs, offering a cost-effective and stable alternative to spiro-OMeTAD.
研究不足
The study highlights the need for further optimization of the functionalized PVK derivatives to match or exceed the performance of spiro-OMeTAD in all aspects, including efficiency and stability under various conditions.
