Molecular strategies to increase robustness of organic semiconductors for application in photovoltaic and photoelectrochemical devices
Over the past four decades, π-conjugated organic semiconductors have attracted significant attention from both academic and industrial laboratories due to a wealth of potential applications in solution-processed, inexpensive and high performance transistors and photovoltaic devices. More recently, organic semiconductors are attracting increasing attention to application in diverse fields such as bioelectronics and artificial photosynthesis. Thus understanding and improving their robust operation in a variety of challenging environments is a critical task. LIMNO’s research with organic semiconductors revolves around the development of molecular morphology control strategies using conjugation-break spacers, the demonstration compatibilization strategies, and investigations of covalently-linked block and network polymers, which afford tunable charge transport and solvent tolerance—making them promising for application as charge-transport interlayers in all-solution processed devices. In addition, the application of bulk-heterojunctions to artificial photosynthesis via photoelectrochemical water splitting is an emerging topic of strong interest. See the references below for more information.
