Application

IEICO-4Cl is a transparent, low-bandgap non-fullerene acceptor. It is a chlorinated derivative of IEICO, which imparts it with a lower optical bandgap and lower energy levels. The weak photon absorption in the visible spectrum of IEICO-4Cl, allows high-performance organic solar cells to be fabricated with outstanding transparency. Furthermore, changing the polymer acceptor pairing with IEICO-4Cl allows tuning of the color of the solar cell device fabricated.

Semitransparent organic solar cells (OSCs) show attractive potential in power-generating windows. However, the development of semitransparent OSCs is lagging behind opaque OSCs. Here, an ultralow-bandgap nonfullerene acceptor, "IEICO-4Cl", is designed and synthesized, whose absorption spectrum is mainly located in the
