研究目的
Investigating the fabrication of transparent conductive electrodes (TCEs) via layer-by-layer (LBL) deposition of silver nanowires (AgNWs) and their application in organic photovoltaic (OPV) devices.
研究成果
The study successfully fabricated transparent conductive AgNW electrodes with optoelectronic properties comparable to ITO. The LBL deposition technique allowed for control over the optical and electrical properties of the films. The fabricated OPV device demonstrated the potential of AgNW electrodes as an alternative to ITO, despite the current limitations in device performance.
研究不足
The high surface roughness of LBL assembled AgNWs electrodes may limit their application in devices requiring smooth surfaces. The PCE of the OPV device was relatively low compared to commercial standards.
1：Experimental Design and Method Selection:
The study employed LBL deposition technique for fabricating AgNW-based TCEs, using 1,3-propanedithiol (PDT) as a linker. Thermal annealing was applied to enhance electrical conductivity.
2：Sample Selection and Data Sources:
Glass substrates were functionalized with (3-Mercaptopropyl)trimethoxysilane (MPTES) for AgNW coating. AgNWs were purchased from ACS Materials.
3：List of Experimental Equipment and Materials:
UV-Vis spectrometer, FE-SEM, OM, AFM, four-point probe method for sheet resistance measurement, and thermal annealing equipment were used.
4：Experimental Procedures and Operational Workflow:
Functionalization of glass substrates, LBL deposition of AgNWs, thermal annealing, and characterization of the films.
5：Data Analysis Methods:
Optical transmittance and sheet resistance measurements were analyzed to evaluate the performance of the TCEs.
