P-24 is a polymeric hole transport material. It can be used as the hole transport layer (HTL) in both n-i-p and p-i-n perovskite solar cell architectures.
• For n-i-p devices, P-24 is deposited using conventional solution-coating techniques.
• For p-i-n devices, P-24 HTL designed to replace the conventional self-assembled monolayer. It eliminates the need for a NiOx bottom contact while maintaining excellent interfacial performance. P-24 is compatible with perovskite layers deposited by either vacuum- or solution-based processes.
