Applications of Truxene and Its Congeners in Solar Cells: A Recent Update

A variety of reports on the truxene and its derivatives have marked the embarkment of the incredible modern era in diverse fields for the human welfare. Among the various potential applications of these versatile systems, organic solar cells (OSCs)/organic photovoltaics (OPVs), have drawn a considerable interest of the research community worldwide in the last decade. In this systematic review article, we have mainly focused to "shade light" onto the recently developed truxene-based architectures useful in OSCs. The authors believe that this review article, on an emerging topic of current era, will be very useful to the researchers working in the arena of organic electronic in general and solar cells in particular. Moreover, we feel that truxene-based materials will provide a new direction to the organic solar cells applications in near future because of their high thermal stability, exceptional solubility while holding solubilizing chains, and the ease with which they are being functionalized or modified.
