New bithiophene molecules for organic photovoltaics

What is it about?

A new material for organic photovoltaics based the bithiophene family of molecules has been demonstrated. Bilayer devices fabricated with this material as an electron acceptor and boron subphthalocyanine chloride (SubPc) as electron donor high efficiency (2.6%) high voltage (1.4V) devices.

Why is it important?

Establishing new families of molecules in the field of OPVs is important to create a library of efficient materials for a variety of application areas. Here we also demonstrate that C60 molecules which are used as a ubiquitous electron acceptor can be replaced with another type of molecule.
