General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, are prone to degradation in ambient conditions.Click here for more information.

Application

PBDB-T, a conjugated push-pull medium bandgap polymeric donor, can be used as a donor molecule that can be used in polymeric solar cells (PSCs). It can also be used in the fabrication of organic thin-film transistors (OTFTs).
