Dye-sensitized solar cells (DSSCs) are a promising type of third-generation photovoltaic devices known for their low cost, eco-friendly materials, and ease of fabrication. The porosity of the materials used in DSSCs, particularly the photoanode, plays a crucial role in determining their efficiency and stability. This synthesis aims to explore the relationship between porosity and the stability of DSSCs based on multiple research studies.
Optimal Porosity for Maximum Efficiency:
Porosity and Long-Term Stability:
Porosity and Charge Transfer:
Porosity and Mechanical Stability:
The relationship between porosity and the stability of DSSCs is multifaceted. Optimal porosity levels are crucial for balancing light absorption, electron diffusion, and mechanical stability. While high porosity can enhance dye adsorption and light scattering, it may also lead to mechanical instability and reduced performance if not properly managed. Conversely, lower porosity can improve charge transfer and reduce recombination, contributing to higher efficiency and stability. Therefore, achieving an optimal porosity level is essential for maximizing the performance and longevity of DSSCs.
