Recent article in Joule on single-source vapor deposited perovskites: a collaboration with Monica Morales-Masis’s team

September 25, 2024

We are excited to announce the publication of our latest collaboration published in Joule, marking a significant advancement in the field of perovskite photovoltaics. This work is the result of a fruitful collaboration with Monica Morales-Masis's team, where we explored the potential of pulsed laser deposition (PLD) for fabricating halide perovskite solar cells.

Vapor-phase processes have long been underrepresented in the field, largely due to the challenges posed by the differing volatilities of perovskite precursors. Our work addresses this issue by utilizing PLD to transfer complex chemical compositions from a single-source target in just one step. We demonstrated the successful fabrication of Cl-passivated MA₁₋ₓFAₓPbI₃ films, significantly enhancing the performance of perovskite absorbers. Furthermore, 2D surface passivation techniques were applied, which further boosted the device efficiencies.

Key achievements from this study include:

• The first demonstration of one-step, single-source deposition of Cl-passivated MA₁₋ₓFAₓPbI₃ films using PLD.
• Surface passivation with 2D layers to improve absorber performance.
• Achieving power conversion efficiencies of up to 19.7% in p-i-n solar devices.
• Reporting the highest efficiency for a single-source vapor-phase deposition method in halide perovskite photovoltaics.

This research underscores the potential of scalable vapor-phase techniques in advancing perovskite solar cell technology, paving the way for future industrial applications. We look forward to continuing our collaboration with Monica Morales-Masis’s team as we push the boundaries of perovskite solar cell fabrication.
