NUMERICAL STUDY OF MECHANICAL PROPERTIES OF HYBRID SOLAR CELL THIN FILM LAYERS BY NANOINDENTATION
Abstract:
Hybrid solar cells have gained significant attention in recent years due to their potential to combine the advantages of different materials, resulting in improved performance and efficiency. Understanding the mechanical properties of the thin film layers in hybrid solar cells is crucial for designing robust and reliable devices. In this study, a numerical approach involving nanoindentation is employed to investigate the mechanical properties of hybrid solar cell thin film layers.
The numerical model used in this study incorporates the mechanical behavior of individual constituents within the hybrid solar cell thin film layers, such as organic and inorganic materials. Material properties, including elastic modulus and hardness, are assigned to each constituent based on experimental data and theoretical models. The finite element method is employed to simulate the nanoindentation process, allowing for the determination of mechanical properties at the nanoscale.
The effects of various parameters, such as film thickness, composition, and layer interfaces, on the mechanical properties of the hybrid solar cell thin film layers are systematically investigated. The numerical simulations provide insights into the load-displacement response during the nanoindentation process, enabling the characterization of mechanical properties, such as elastic modulus and hardness, of the individual layers.
The results obtained from the numerical study contribute to the understanding of the mechanical behavior of hybrid solar cell thin film layers. This information is valuable for optimizing the design and fabrication processes of hybrid solar cells, improving their structural integrity, and ensuring long-term performance under various mechanical stresses.
