IDIC-4Cl, non-fullerene acceptor for all-small-molecule or polymer solar cells

Low price, high purity (≥99%) IDIC-4Cl available for priority dispatch and worldwide shipping

IDIC-4Cl is the chlorinated derivative of IDIC that is commonly used as a non-fullerene acceptor in highly efficient all-small-molecule or polymer solar cells.

The introduction of the chlorine atoms on the peripheral end groups in IDIC-4Cl leads to a more planar structure with good crystallinity.

A binary all-small-molecule OSCs obtained the highest efficiency of 9.58% with ZR1 as the small molecule donor and IDIC-4Cl as the non-fullerene acceptor (Device 1). Post treatment with thermal annealing (TA) and solvent vapor annealing (SVA) of active layer materials with BSCl as small molecule donor and IDIC-4Cl as the non-fullerene acceptor, a a PCE of 13.03% was achieved (Device 2).
