一个飞速发展的领域:非富勒烯有机太阳能电池受体材料

Abooming area:non-fullerene acceptors for organic solar cells

有机太阳能电池作为解决能源问题的重要手段之一,2006年以来得到了深入的研究.其电子受体材料较多地局限在富勒烯及其衍生物领域,由于其光谱吸收窄、溶解性差、成本高、生产过程中环境不友好等问题,迫使科学家们寻找新的受体材料.近年来,非富勒烯电子受体材料吸引了科学家们的关注.非富勒烯受体材料的光谱吸收宽,溶解性好,结构可控,易加工等特点决定了其在有机太阳能电池领域有广泛的应用.综述了2011年以来非富勒烯有机太阳能电池受体材料领域的进展,并对其将来的发展进行了展望.

Organic solar cells have been extensively investigated in the last decade because they are one of the very important so-lutions to the global energy crisis. While predominant electron acceptor materials for organic solar cell are focused on fullerene and its derivatives, scientists are now more desperately looking for new alternative acceptor materials because fullerene acceptors face the challenges of narrow absorption spectrum, low solubility, high cost and non-environmental friendly synthesis processes. Non- fullerene electron acceptors have drawn great attention recently and have been widely used in organic solar cells because they have the great advantages of wide absorption spectrum, high solubility, precise structural controllability, and good processability. In this review paper,we summarize the most significant progresses in the area of non-fullerene organic solar cell acceptors during the last 6 years and we look forward to a bright future of non-fullerene organic solar cells.
