文摘

Four indeno[1,2-b]indole-based new organic dyes have been synthesized. These dyes were designed into a D–π–A structure and applied in DSSCs. Different acceptors were used to tune the photoelectric properties of the dyes. A highest PCE of 6.29% was achieved by the dye with a cyanoacrylic acid acceptor.
