High-Efficiency Perovskite Solar Cells with Sputtered Metal Contacts.
ACS Appl Mater Interfaces
November 2022
Sputter deposition produces dense, uniform, adhesive, and scalable metal contacts for perovskite solar cells (PSCs). However, sputter deposition damages the other layers of the PSC. We here report that the damage caused by sputtering metal contacts can be reversed by aerial oxidation.

- The optimization of materials often involves trade-offs between conflicting objectives, which can be represented by the Pareto front.
- The self-driving laboratory, Ada, identifies conditions for creating palladium films with lower processing temperatures (below 200 °C) compared to previous methods (250 °C), expanding the potential for different substrate coatings.
- Ada’s findings lead to the spray coating of palladium films with moderate conductivity (1.1 × 10 S m at 191 °C) and improved conductivity (2.0 × 10 S m at 226 °C), demonstrating the effectiveness of automated exploration in material discovery.
