Namely, a heated solvent vapor is utilized to modify an active layer after the active layer of the organic solar cells is formed, which ensures a flatness and an uniformity thereof and increases a crystallinity of the active layer and an element charge transport rate so that a power conversion efficiency of the large area organic solar cells is increased, a proceeding time is quite short, and the performance thereof is quite obvious. Therefore, the method not only reduces the cost by a large area production but obtains organic solar cells with higher conversion efficiency.

Abstract: A bulk heterojunction solar cell comprises an electron donor, an electron acceptor, and a multi-substituted fullerene derivative. The electron acceptor further comprises a nano-scale electron acceptor material, and a meso-scale mixture of electron donor/acceptor material. The multi-substituted fullerene derivative further comprises a single fullerene structure and a multi-substituted derivative connected to the single fullerene structure. The multi-substituted fullerene derivative is utilized to prevent the meso-scale mixture of electron donor/acceptor material from large-scale segregation of acceptor over a specific temperature after a specific period (thermally unstable state), thereby maintaining the thermal stability and the sizes of the nano-scale acceptor material and meso-scale mixture of electron donor/acceptor material. In the conventional knowledge, the large-scale segregation and corresponding degradation of power efficiency are cause mainly by the nano-scale acceptor material.
