研究目的
Investigating the effects of low-dimensional diffusion barriers on the operational stability of high-efficiency perovskite solar cell modules by reducing the unwanted interfacial diffusion of ions.
研究成果
The introduction of low-dimensional diffusion barriers significantly improved the operational stability of perovskite solar cell modules, with the 2D-DBL showing the best performance in suppressing iodide diffusion and maintaining high efficiency over 1,000 hours of testing.
研究不足
The study focuses on the stability under specific conditions (85°C and light soaking) and may not cover all potential degradation mechanisms in real-world applications.
1：Experimental Design and Method Selection:
The study introduced low-dimensional diffusion barriers (0D, 1D, and 2D) to block the diffusion channels of volatile iodide in perovskite solar cell modules.
2：Sample Selection and Data Sources:
Perovskite films and solar modules were prepared and characterized.
3：List of Experimental Equipment and Materials:
Included Al2O3 nanoparticles for 0D-DBL, PDMS for 1D-DBL, and g-C3N4 for 2D-DBL.
4：Experimental Procedures and Operational Workflow:
The diffusion barriers were applied to the perovskite films, and the modules were subjected to aging tests under heat and light.
5：Data Analysis Methods:
The performance and stability of the modules were analyzed using J-V curves, IPCE spectra, and transient photovoltage and photocurrent decay measurements.
