Non-fullerene acceptor compound containing benzoselenadiazole and organic optoelectronic device including the same

A semiconductor mixed material comprises an electron donor, a first electron acceptor and a second electron acceptor. The first electron donor is a conjugated polymer. The energy gap of the first electron acceptor is less than 1.4 eV. At least one of the molecular stackability, π-π*stackability, and crystallinity of the second electron acceptor is smaller than the first electron acceptor. The electron donor system is configured to be a matrix to blend the first electron acceptor and the second electron acceptor. The present invention also provides an organic electronic device including the semiconductor mixed material.

Semiconductor mixed material and application thereof

Organic photovoltaic device comprises a first electrode, a first carrier transfer later, an active layer, a second carrier transfer layer and a second electrode. The first electrode is a transparent electrode. The active layer includes at least one electron donor, a first electron acceptor, and a second electron acceptor. Wherein, the electron donor is an organic polymer. The first electron acceptor is a crystalline material, and the self-molecule stacking distance of the first electron acceptor is less than 4 Å. The second electron acceptor is a crystal destruction material, and the second electron acceptor includes a fullerene derivative. The organic photovoltaic device of the present invention not only has a controllable morphology formation but also can enhance fill factor and improve power conversion efficiency.
