چکیده
A new evaporable electron acceptor material for organic photovoltaics based on N-ethyl barbituric acid bithiophene (EBB) has been demonstrated. Bilayer devices fabricated with this non-fullerene acceptor and boron subphthalocyanine chloride (SubPc) donor produce power conversion efficiencies as high as 2.6% with an extremely large open-circuit voltage approaching 1.4 V.

High open circuit voltage organic solar cells based upon fullerene free bulk heterojunction active layers
We have recently reported on a small organic molecule containing a bithiophene core with end-capping phthalimide units (PthTh2Pth) that exhibited a H-aggregation tendency in the solid state and high electron mobility in organic field effect transistors. In this contribution, we have studied both the physical and electrical properties of poly(3-hexylthiophene) (P3HT) and PthTh2Pth thin films by ...
متن کاملDevelopment of donor–acceptor copolymers based on dioxocycloalkene-annelated thiophenes as acceptor units for organic photovoltaic materials
Organic photovoltaics (OPVs) have attracted considerable attention over the past two decades not only because of their potential for generating renewable energy but also because of their favorable properties, such as low cost, low weight, solution processability and large-area manufacturability. The active layer of OPVs is based on the concept of the bulk-heterojunction configuration, which com...
متن کاملMolecular helices as electron acceptors in high-performance bulk heterojunction solar cells
Despite numerous organic semiconducting materials synthesized for organic photovoltaics in the past decade, fullerenes are widely used as electron acceptors in highly efficient bulk-heterojunction solar cells. None of the non-fullerene bulk heterojunction solar cells have achieved efficiencies as high as fullerene-based solar cells. Design principles for fullerene-free acceptors remain unclear ...
