Ultrafast Charge Injection Dynamics in π −Conjugated Zinc Porphyrin and Fullerene bulk heterojunction blend

Chinmoy Biswas, Dipin Tomar, Jyotishman Dasgupta, and Sai Santosh Kumar Raavi

Not Accessible

Your library or personal account may give you access

Abstract

Ultrafast photo charge-generation kinetics are investigated in bulk heterojunction blend of zinc porphyrin and fullerene utilizing near infra-red femtosecond transient absorption spectroscopy. Data revealed charge formation < 100fs and long-lived charge kinetics.
