The invention discloses a high-efficiency ternary organic solar cell and a preparation method thereof. The active layer of the organic solar cell is obtained by blending a donor material and a receptor material. A ternary organic solar cell containing both non-fullerene and fullerene receptors is prepared by introducing a third component, fullerene acceptor, into the active layer of a binary non-fullerene organic solar cell.
