Photovoltaics: A Tetraperylene Diimides Based 3D Nonfullerene Acceptor for Efficient Organic Photovoltaics (Adv. Sci. 4/2015)

A 3D organic dye has been developed to fulfill the multi‐dimensional charge‐ and energy‐harvest in bulk‐heterojunction thin film organic solar cells to convert sunlight into electricity. In article number 1500014, H.‐Z. Chen, A. K.‐Y. Jen, and co‐workers discuss how the simple, yet delicate design strategy transforms the original planar sub‐units into a 3D molecular geometry with a compact tetrahedron core, of which four sub‐units are interlocked to reinforce structural rigidity of the molecule. The cover was designed by Xiaoming Lu. [Image: see text]
