Utilization of renewable energy sources has become one of the most important and necessary scientific and technological advancements. Since the report of Grätzel in 1991, the study of dye-sensitized solar cells (DSSCs) have received steadily growing interest from both academic and industrial protagonists as an alternative to conventional metal-free based solar cells because of their low low-cost materials and production, large-scale manufacturing process, and environmentally-friendly properties. Here, the development of new metal-free organic dyes based on indolo[3,2-b]indole donor backbone was designed, synthesized, and utilized as dye-sensitized solar cells (DSSCs). One of them (dye 2) can provide an enhanced overall conversion efficiency of 7.86% compared to the 8.08% of the standard commercial N719-based cell, under the same global standard condition 1.5 AM.
