研究目的
To develop an auxiliary additive of HTLs for high-performance PSCs by introducing a metal–organic framework-derived 2D graphitic N-rich porous carbon (NPC) into the HTLs.
研究成果
The introduction of MOF-derived 2D graphitic NPC as an auxiliary additive in HTLs significantly improves the PCE and stability of PSCs. The NPC enhances hole extraction and migration, reduces lithium salt aggregation, and prevents moisture erosion, leading to highly efficient and long-term stable PSC devices.
研究不足
The study focuses on the introduction of NPC into HTLs and its effects on PSC performance and stability. The limitations include the specific conditions under which the NPC was tested and the need for further optimization of NPC content for maximum efficiency and stability.
1：Experimental Design and Method Selection:
The study involves the preparation of a 2D In-based MOF In-Aipa and its pyrolysis into graphitic NPC for use as an auxiliary additive in HTLs of PSCs.
2：Sample Selection and Data Sources:
The samples include PSCs with a typical n-i-p configuration of FTO/c-TiO2/Cs
3：05FA81MA14PbI55Br45/HTL/Au. List of Experimental Equipment and Materials:
SEM, TEM, AFM, XRD, XPS, CV, and other characterization tools were used.
4：Experimental Procedures and Operational Workflow:
The NPC was introduced into the HTLs, and the performance of PSCs was evaluated through J-V curves, steady-state and time-dependent photoluminescence spectra, and stability tests.
5：Data Analysis Methods:
The data were analyzed to evaluate the PCE, FF, and stability of PSCs with and without NPC.
