Summary
This study introduces a new strategy for perovskite solar modules (PSMs) to achieve high efficiency and stability. By optimizing composition and passivation, these solar modules demonstrate robust performance for commercial viability.
Area of Science:
- Materials Science
- Renewable Energy
- Photovoltaics
Background:
- Perovskite solar modules (PSMs) require high power conversion efficiency (PCE) and long-term stability for commercialization.
- Scaling up perovskite solar cells (PSCs) from lab to module often compromises efficiency and stability due to crystallization, defect passivation, and degradation issues.
Purpose of the Study:
- To resolve challenges in translating lab-scale PSCs to scalable PSMs.
- To develop a mechanistic framework for operationally stable PSMs under industrial conditions.
Main Methods:
- Deconstructed compositional origins of stability, identifying MA-free Cs-FA composition.
- Tailored crystallization pathways for air-processed scalable-coating via Br incorporation in CsPbX3.
- Developed CHCA as a blade-coating-compatible passivator for uniform defect suppression.
Main Results:
- Achieved improved PCEs of 26.1% (0.646 cm2) and 22.8% (20.8 cm2).
- Demonstrated exceptional operational stability: ~3200 h T96 for PSC and ~2000 h T84 for PSM.
- Yielded dense, defect-suppressed films with reconciled precursor solubility, nucleation kinetics, and α-phase stability.
Conclusions:
- Established a three-pronged strategy to enhance PSM efficiency and stability.
- Identified intrinsically robust Cs-FA composition and effective scalable passivation techniques.
- Provided a framework for developing stable perovskite solar modules for industrial applications.
