内容記述 |
Single-walled carbon nanotubes (SWCNTs) typically possess p-type semiconducting properties when exposed to air and oxygen, making them commonly used as anodes in perovskite solar cell (PSC) devices. In this study, we proposed a facile n-type doping strategy to enable SWCNTs to function as cathodes in inverted (p–i–n) PSCs [glass/indium tin oxide/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)/MAPbI3/n-doped SWCNT:PCBM]. Organophosphorus compounds, including triphenylphosphine (TPP), 1,2-bis(diphenylphosphino)ethane (DPPE), and 1,1′-bis(diphenylphosphino)ferrocene (DPPF), were utilized as molecular n-type dopants for SWCNT electrodes. The doping mechanisms and their application in PSCs were validated through computational and experimental studies. Overcoating doped SWCNTs with PCBM was found to be essential to remove uncoordinated dopants, enhancing surface contact with the perovskite layer and maintaining n-type characteristics. This process mitigated energy mismatches caused by shallow LUMO levels of phosphine-based dopants, thereby improving electron transport and optimizing energy levels for efficient charge transfer. Inverted PSCs incorporating DPPE-doped SWCNT electrodes demonstrated significant improvements in device efficiency, increasing from 5.1% to 8.03%. From the carrier lifetime studies, these improvements are attributed to rapid electron transfer and reduced recombination at the interface between the doped SWCNTs and the bulk perovskite. Notably, the n-type dopants that induced significant energy level shifts adversely affected the PSC performance. The hydrophobic nature of the doped electrodes contributed to the long-term stability of the devices. Unencapsulated PSCs with doped electrodes retained 50% of their initial efficiency after 500 h of storage under controlled humidity (25% RH), temperature (25 °C), and ambient light (300 lux) conditions. |
