Summary
Different perovskite solar cell fabrication methods impact charge carrier behavior. Understanding these differences is key to designing efficient perovskite solar cells for specific applications.
Area of Science:
- Materials Science
- Photovoltaics

- Fabrication methods significantly influence device performance, yet carrier dynamics differences remain understudied.
- Understanding charge carrier behavior is crucial for optimizing PSC efficiency.
Purpose of the Study:
- To compare carrier behaviors in spin-coated and coevaporated MAPbI3 perovskite films.
- To investigate the influence of fabrication methods on charge carrier dynamics.
- To provide insights for tailored perovskite layer design in PSCs.
Main Methods:
- Time-resolved photoluminescence spectroscopy.
- Carrier dynamics simulation.
- Comparison of one-step spin-coated and dual-source coevaporated MAPbI3 films.
Main Results:
- Distinct carrier behaviors were observed between spin-coated and coevaporated perovskite films.
- Fabrication-induced strains, lattice orientations, and buried-layer defects influence carrier dynamics.
- Preparation methods lead to variations in charge carrier behavior.
Conclusions:
- Fabrication processes critically affect charge carrier dynamics in perovskite films.
- Tailoring perovskite layer fabrication is essential for optimizing PSCs.
- Design considerations should account for specific carrier behavior needs in planar or tandem PSC structures.
