Hybrid nonfullerene acceptors based on thieno[2′,3′:4,5]thieno[3,2-b]indole for efficient organic solar cells
The emergence of non-fullerene acceptors (NFAs) has revived organic solar cells (OSCs) and promoted its industrialization significantly. Nowadays there are two main kinds of fused-ring electron acceptors: ITIC series and Y-series NFAs. Herein, two hybrid NFAs TIT-H and TIT-EH integrated ITIC series and Y-series NFAs have been developed, which based on thieno[2′,3′:4,5]thieno[3,2-b]indole-thiophene with one spiro group. TIT-H and TIT-EH both exhibited excellent thermal stability, low optical bandgaps of ∼1.5 eV, planar molecular geometries, and suitable energy levels. As a result, OSCs based on PM6:TIT-EH afforded a decent PCE of 13.32 %, with an VOC of 0.856 V, a JSC of 23.50 mA/cm2 and a FF of 65.91 %, which was due to the suitable intermolecular interactions of TIT-EH, balanced charge carrier mobilities and face-on orientation in blend films. As comparison, PM6:TIT-H cell exhibited lower PCE of 12.26 %. These results demonstrated that hybrid NFAs are promising for OSC applications.
期刊介绍：
This journal is an international medium for the rapid publication of original research papers, short communications and subject reviews dealing with research on and applications of electronic polymers and electronic molecular materials including novel carbon architectures. These functional materials have the properties of metals, semiconductors or magnets and are distinguishable from elemental and alloy/binary metals, semiconductors and magnets.
