Beschreibung

Allgemeine Beschreibung

PCPDTBT is a low band gap polymer that is used as a donor material with a high photovoltaic efficiency. It can form blends with a variety of conducting polymers which can be used to enhance the power conversion efficiency (PCE) in an electrochemical device.

Soluble in cyclohexane, toluene, chloroform, and THF

Anwendung

PCPDTBT can form a donor/acceptor blend with PCBM which can be used as a polymeric backbone for use in the fabrication of organic solar cells.
