In a bid to enhance perovskite solar cell (PSC) performance and stability, a novel interfacial buffer layer called Ethyl p-nitrobenzoate (EPN) was introduced. EPN improved film quality, reduced defect density, relieved interfacial stress, and suppressed nonradiative recombination at the interface. This innovation led to a high 23.16% power conversion efficiency and improved device stability, showcasing the potential of multifunctional interfacial buffer layers in high-performance PSCs.
How Paios was used
TPC, TPV, IMPS, IMVS, and built-in potential were carried out via PAIOS in the structure of ITO/SnO2/(EPN)/perovskite/Spiro-OMeTAD/Ag, and the results were fitted using the companion software of PAIOS.
