Researchers used quantum chemical calculations and device simulations to study fluorinated self-assembled monolayers on perovskite solar cells, finding that difluorination improves interfacial defect passivation but reduces hole transport, while monofluorination balances these effects better. Simulated devices with difluorinated monolayers showed a theoretical power conversion efficiency of 20.25% for a MA0.5FA0.5PbI3 perovskite architecture.

This Wire brief sits within Fusion42's coverage of Advanced Materials, Semiconductors and Clean Energy.

◆ ◆ The Wire takeaway

You can choose fluorination levels to tune the trade-off between defect passivation and charge transport in perovskite solar layers. Refining monolayer chemistry to balance these traits may give your solar cells a competitive edge in efficiency and stability.
