Design and Development of a Rapid Thermal Annealing Setup for Fast Processing of Solar Cells

Introduction

Rapid Thermal Processing(RTP)
Potential to overcome challenges such as
1. Scalability
2. Stability landscape Amenable to Roll to roll processing Processing in controlled atmosphere Low thermal budget of processing

RESULTS & DISCUSSION

CONCLUSION

• Compact and pinhole free surface morphology of c- TiO2.
• Pinhole free surface morphology of FAPbI3, with large grain size.
• a- phase of FAPbI3 was found to be more stable when annealed in RTP.
• RTP can be utilized for roll to roll processing of perovskite cell.
• Much reduced thermal budget of processing compared to Hotplate.
• Processing completed in few hours compared to a day.
