IEICO-4Cl, low bandgap NFA with absorption into the near-infrared

Available for priority dispatch with free shipping on qualifying orders


IEICO-4Cl, a chlorinated version of IEICO-4F, has a structure with an electron-donating fused indaceno[1,2-b:5,6-b′]dithiophene (IDT) core flanked by two electron-withdrawing terminals, 2-(5,6-dichloro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (IC-2Cl). IEICO-4Cl has an ultralow bandgap of 1.23 eV with weak absorption in the visible region, but extends its main absorption into the near-infrared (NIR) region (745-945 nm) with maximum absorption around 880 nm and an absorption onset of ≈1010 nm.

Organic tandem solar cell with PBDB-TF:IT-4F as active layer for the front cell and PTB7-Th:IEICO-4Cl:PC71BM as active layer for the real cell gained a power conversion efficiency (PCE) of 15.26%.
