Summary
A new dual-functional additive, 1-adamantanethiol (ADSH), enhances perovskite solar cells (PSCs) by improving defect passivation and stability. This boosts power conversion efficiency (PCE) and device longevity.
Area of Science:
- Materials Science
- Renewable Energy
Background:
- Perovskite solar cells (PSCs) offer low-cost fabrication but face challenges in defect passivation and environmental stability.
- Functional additives are crucial for enhancing PSC performance and durability.
Purpose of the Study:
- To introduce a dual-functional additive, 1-adamantanethiol (ADSH), for improved perovskite film quality.
- To enhance the efficiency and operational stability of PSC devices.
Main Methods:
- Incorporation of 1-adamantanethiol (ADSH) during perovskite crystallization and film formation.
- Characterization of the modified perovskite films and device performance evaluation.
Main Results:
- ADSH additive improved perovskite film quality through defect passivation and moisture resistance.
- The ADSH-modified PSC achieved a power conversion efficiency (PCE) of 25.31%.
- The modified devices demonstrated stable operation for over 800 hours.
Conclusions:
- 1-adamantanethiol (ADSH) is an effective dual-functional additive for PSCs.
- ADSH enhances both the efficiency and long-term stability of perovskite solar cells.
