Organic solar cell has become a research hotspot because of its low cost, good flexibility, simple process and wide source of raw materials. Acceptor materials play an important role in improving the efficiency of organic solar cells. Compared with fullerene materials, non fullerene small molecular materials have attracted much attention due to their flexible molecular structure design and high absorption coefficient. At present, the energy conversion efficiency of solar cells with small molecules as acceptors has improved rapidly, reaching 18.22%.<br>
