چکیده

We report a novel diindenothieno[2,3-b]thiophene ladder-type hexacyclic arene for constructing a donor-acceptor copolymer PDITTDTBT. A device based on PDITTDTBT:PC(71)BM exhibited a high V(oc) of 0.92 V with an impressive PCE of 5.8%, while a PDITTDTBT:DMPCBA-based device showed an extra high V(oc) of 1.14 V.

Diindenothieno[2,3-b]thiophene arene for efficient organic photovoltaics with an extra high open-circuit voltage of 1.14 evw

Over the past decade, considerable progress has been made in the development of organic materials for photovoltaic applications. Bulk heterojunction (BHJ) using n-type and a p-type semiconductor materials in the active layer is the most widely adopted device architecture to ensure maximum internal donor–acceptor (D–A) interfacial area for efficient charge separation. The most critical challenge...

Linked‐Acceptor Type Conjugated Polymer for High Performance Organic Photovoltaics with an Open‐Circuit Voltage Exceeding 1 V

A linked-acceptor type conjugated polymer is designed and sythesized based on 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene (BDTT) and linked-thieno[3,4-c]pyrrole-4,6-dione (LTPD). This polymer uses alkyl-substituted thiophene as a bridge. The PBDTT-LTPD includes two TPD units in one repeating unit, which can enhance acceptor density in the polymer backbone and lower the ...

Low-Voltage Organic Transistors Based on Tetraceno[2,3‐b]thiophene: Contact Resistance and Air Stability

The small-molecule organic semiconductor tetraceno[2,3-b]thiophene has been synthesized through an environmentally friendly synthetic route, utilizing NaBH4, rather than Al/HgCl2, for the reduction of the quinone. Lowvoltage organic thin-film transistors (TFTs) have been fabricated using tetraceno[2,3-b]thiophene and, for comparison, pentacene and anthradithiophene as the semiconductor. The tet...

Structure and Optical Bandgap Relationship of π-Conjugated Systems

In bulk heterojunction photovoltaic systems both the open-circuit voltage as well as the short-circuit current, and hence the power conversion efficiency, are dependent on the optical bandgap of the electron-donor material. While first-principles methods are computationally intensive, simpler model Hamiltonian approaches typically suffer from one or more flaws: inability to optimize the geometr...
