研究目的
The controllable oxidation of spiro-OMeTAD and improving the stability of hole-transport materials (HTMs) layer are crucial for good performance and stability of perovskite solar cells (PSCs).
研究成果
The hybrid POM@Cu-BTC not only facilitates rapid oxidation of spiro-OMeTAD but also leads to improved stability of devices. The optimal doped device had enhanced conductivity and more effective carrier extraction and reduced charge recombination at the perovskite/HTM interface.
研究不足
The study does not address the scalability of the synthesis process for POM@Cu-BTC or the long-term stability under extreme environmental conditions.
1：Experimental Design and Method Selection:
The study involves the synthesis of a hybrid oxidant POM@Cu-BTC for the oxidation of spiro-OMeTAD with Li-TFSI and TBP.
2：Sample Selection and Data Sources:
The samples used include perovskite solar cells with different HTM layers.
3：List of Experimental Equipment and Materials:
The materials include spiro-OMeTAD, Li-TFSI, TBP, and the hybrid POM@Cu-BTC.
4：Experimental Procedures and Operational Workflow:
The POM@Cu-BTC was introduced to the HTM layer as a dopant, and the performance of the PSCs was measured.
5：Data Analysis Methods:
The performance of the PSCs was analyzed using UV/Vis spectra, cyclic voltammetry curves, current–voltage plots, and ESR spectra.
