研究目的
Investigating the effects of plasmonic Au@SiO2 nanoparticles on the performance of polymer solar cells.
研究成果
Doping of Au@SiO2 NPs resulted in a significant light absorption and PCE increase that benefited from the pronounced increase of Jsc. A maximal PCE of 9.55% with a 16.3% enhancement was achieved for the PTB7-Th: PC71BM devices with big Au@SiO2 NPs.
研究不足
The influence of NPs on the morphology of active layer and the thickness of the PEDOT: PSS.
1:Experimental Design and Method Selection:
Prepared plasmonic Au@SiO2 NPs by a modified method and doped them into PEDOT: PSS layer of PC71BM-based PSCs.
2:Sample Selection and Data Sources:
Used PTB7-Th/PC71BM or PBDB-T/PC71BM as the active layer.
3:List of Experimental Equipment and Materials:
Transmission electron microscope (TEM), high-resolution TEM (HRTEM), UV-Vis absorption spectra.
4:Experimental Procedures and Operational Workflow:
Fabricated PSCs with a typically conventional structure of ITO/PEDOT: PSS (with or without NPs)/Active layer/LiF (
5:6 nm)/Al (100 nm). Data Analysis Methods:
Measured surface roughness (RMS) of doped blend films by AFM, hole mobility, and series resistance (Rs) of devices.
