The Front Cover shows a schematic illustration of a donor–acceptor system bearing a TPA–NDI–fullerene triad (TPA=triphenylamine; NDI=naphthalenediimide). Organic bulk heterojunction solar cells were fabricated using the triad as an n‐type semiconductor along with the conventional donor polymer poly(3‐hexylthiophene). The power conversion efficiency reached 3.03% before annealing and 4.85% after annealing in the optimized devices. Thus, the present triad for n‐type semiconductor solar cells may attract significant attention due to its potential application in the conversion of solar energy to electrical energy.

封面：三苯胺-萘二酰亚胺-富勒烯三联体：合成，光诱导电荷分离和溶液可加工的异质结太阳能电池（Asian J. Org。Chem。1/2018）

封面显示了带有TPA-NDI-富勒烯三联体（TPA =三苯胺； NDI =萘二酰亚胺）的供体-受体系统的示意图。使用三元组作为n型半导体与常规的施主聚合物聚（3-己基噻吩）一起制造有机体异质结太阳能电池。在优化的器件中，功率转换效率在退火之前达到3.03％，在退火之后达到4.85％。因此，由于其在太阳能转换为电能中的潜在应用，目前用于n型半导体太阳能电池的三合会可能会引起广泛关注。可以在Akhil Gupta，Sidhanath V.
