BiOCl porosity in dssc

Introduction

The porosity of BiOCl (Bismuth Oxychloride) in dye-sensitized solar cells (DSSCs) plays a crucial role in determining the efficiency of these cells. Porosity affects light absorption, electron diffusion, and overall electrical performance, which are critical for the optimal functioning of DSSCs.

Key Insights

Optimal Porosity for Maximum Performance:
- The optimal porosity for maximum I-V output in DSSCs is found to be 0.41. This balance ensures effective light absorption and electron diffusion, leading to improved electrical performance.
Porous BiOCl Micro-flowers for Enhanced Degradation:
- Porous BiOCl micro-flowers constructed from ultrathin nanosheets with nearly 100% {001} facets exposed show superior activity for dye degradation. These facets enhance the adsorption of cationic dyes and facilitate the accumulation of photogenerated electrons, which are crucial for efficient dye photosensitization degradation under visible light.

Conclusion

The porosity of BiOCl in DSSCs is a critical factor influencing their efficiency. An optimal porosity of 0.41 maximizes the I-V output by balancing light absorption and electron diffusion. Additionally, BiOCl micro-flowers with exposed {001} facets significantly enhance dye degradation, contributing to the overall performance of DSSCs.
