研究目的
Investigating rapid and cost-effective fabrication techniques for perovskite solar cells (PSCs) to achieve high throughput manufacturing and commercialization.
研究成果
The study demonstrates that spray coating and slot-die coating, combined with IPL annealing, are effective for rapid fabrication of PSCs. Slot-die coating is preferred for its ability to provide desired patterning with less complexity and environmental concerns. The fabricated devices achieved an efficiency of 8.3%, indicating the potential for high throughput manufacturing of PSCs.
研究不足
The study acknowledges the need for further optimization of annealing parameters and the environmental health and safety issues associated with the atomization of toxic materials in spray coating.
