研究目的
Investigating the difference between OSC and IOSC electrical characteristics, the effect of active layer thickness on their electrical outputs, testing several of ETL and HTL materials to choose between, and improve the charge collection using multi-thin layer electrode rather than a mono-layer.
研究成果
The best efficiency for OSC reaches 5.02% for the Al/TiOx/P3HT:PCBM/ZTZ structure, whereas for IOSC the best structure is Ag/PEDOT:PSS/P3HT:PCBM/ATZ with the best efficiency of 5.46%. The study highlights the importance of layer thickness, material choice, and electrode structure in optimizing solar cell performance.
研究不足
The study is based on simulations using GPVDM software, which may not fully capture all real-world conditions and material behaviors. The performance of the solar cells is also dependent on the specific materials and structures used, which may limit generalizability.
1：Experimental Design and Method Selection:
The study uses GPVDM software for electrical simulation, employing the finite-difference drift-diffusion model for transport and carrier trapping/de-trapping.
2：Sample Selection and Data Sources:
The study focuses on conventional and inverted P3HT:PCBM organic solar cells.
3：List of Experimental Equipment and Materials:
Materials include P3HT:PCBM blend, TiOx, ZnO, PCBM, PEDOT:PSS, P3HT, WO3, Cu2O, Ag, Au, Cu, Al, ITO, FTO, AZO.
4：Experimental Procedures and Operational Workflow:
The thickness of the active layer, ETL, and HTL are varied, and different materials are tested for ETL and HTL. Multi-layer electrodes are also tested.
5：Data Analysis Methods:
The current-voltage characteristic (J-V) is used to extract the main electrical outputs of the solar cell.
