研究目的
Investigating the position effect of arylamine branches on pyrene-based dopant-free hole transport materials for efficient and stable perovskite solar cells.
研究成果
The study demonstrates that the position of arylamine branches on pyrene-based HTMs significantly affects their optical and electronic properties, as well as the performance and stability of PSCs. PYR16, with arylamine branches at the 1,6-positions, shows superior performance and stability compared to PYR27, with branches at the 2,7-positions. This provides a new strategy for designing dopant-free HTMs for efficient and stable PSCs.
研究不足
The study focuses on the position effect of arylamine branches on pyrene-based HTMs, but the impact of other structural modifications or the combination with other materials is not explored. The stability tests are conducted under specific conditions, and the performance under other environmental factors is not investigated.
1：Experimental Design and Method Selection
Two novel HTMs based on pyrene, PYR16 and PYR27, were synthesized by introducing arylamine branches to different positions of the pyrene core. The influence of different positions on the optical and electronic properties and the performance of PSCs were investigated.
2：Sample Selection and Data Sources
The reagents used in synthesis and measurements were all available commercially without further purification. The substrates are patterned fluorine-doped tin-oxide-coated glass.
3：List of Experimental Equipment and Materials
Bruker AVANCE III HD (400 MHz) for NMR, Bruker Autoflex tof/tof III for MALDI-TOF MS, Thermo Evolution 300 UV-Visible spectrometer for UV-vis absorption spectra, TA Q20 instrument for TGA and DSC, FEI Nova 630 for SEM, FluoroMax-4 (HORIBA) for PL and TRPL, Keithley source table for SCLC measurement, Mini Flex 600 for XRD, Bruker Dimension icon for AFM.
4：Experimental Procedures and Operational Workflow
The HTMs were synthesized via Buchwald-Hartwig reaction. The PSCs were fabricated with the structure of FTO/compact-TiO2/mesoporous-TiO2/perovskite/HTM/Au. The performance and stability of the PSCs were tested under various conditions.
5：Data Analysis Methods
The optical and electronic properties of the HTMs were analyzed using UV-Vis absorption spectra, PL and TRPL spectra, CV measurements, and SCLC measurements. The performance of the PSCs was evaluated based on J-V curves and IPCE spectra.
