The first double-layer organic solar cell was proposed by Tang in 1986, and the first BHJ organic solar cell based on fullerene was reported by Heeger in 1995. Fullerene derivatives have been used primarily as acceptors for organic solar cells over the past decades. However, due to the difficult energy level control, narrow absorption spectrum and low morphological stability of the fullerene derivative receptor, the development of non-fullerene acceptors (NFAs) has become essential for the production of high-performance organic solar cells. Compared to fullerene-based acceptors, NFAs are suitable as a replacement for fullerene-based acceptors due to their various advantages such as adjustable absorption spectrum and energy level, stable form, low energy loss and improved solubility. |
