Scalable manufacturing techniques are key to the commercialisation of perovskite solar cells (PSCs), with roll-to-roll (R2R) processes like slot-die coating emerging as transformative technologies. This talk explores advancements in depositing ultra-thin self-assembled monolayers (SAMs) via slot-die coating, demonstrating their potential to replace traditional hole transport layers in flexible PSCs. Through a combination of experimental optimisation and non-destructive spectroscopic analysis, we quantify deposition uniformity and, in particular, material coverage, demonstrating the precision and scalability of this approach.
The talk will address the significant challenges of transitioning to roll-to-roll (R2R) printing, including maintaining coating uniformity across large areas, controlling defect formation during high-speed deposition, and ensuring environmental stability under ambient conditions. It will also explore specific solutions developed for SAM deposition and their implications for the R2R fabrication of perovskite solar cells and modules.
