Challenges in Scaling Up Perovskite Solar Cells
- Uniformity and Morphology Control:
- Deposition Techniques: Achieving uniform films and controlling the perovskite morphology is crucial. The deposition technique plays a significant role in ensuring uniformity across large areas.
- Scaling Methods: Techniques like blade coating, slot-die coating, spray coating, and various printing methods are being explored to replace traditional spin coating for larger areas.
- Long-term Stability:
- Thermal and Light Stability: PSCs struggle with maintaining efficiency over time due to susceptibility to thermal and light degradation, which affects their long-term performance.
- Environmental Factors: Encapsulation and sustainable practices are essential to mitigate these issues and ensure environmental sustainability.
- Efficiency at Larger Scales:
- Maintaining High Efficiency: While PSCs have achieved high efficiencies in small-scale devices, maintaining these levels in large-area modules remains challenging.
- Bandgap and Losses: Increased bandgap can lead to reduced efficiency due to factors like reduced JSC and increased VOC loss.
- Industrialization and Cost:
- Scalable Manufacturing: Transitioning from laboratory-scale to industrial-scale production requires developing cost-effective and reliable manufacturing processes.
- Cost and Environmental Impact: Assessing environmental costs and ensuring sustainable practices throughout the production lifecycle is vital.
- Technological Integration:
- Tandem Devices: Integrating PSCs into tandem devices or modules also poses technical challenges and opportunities for improving overall efficiency and stability.
