Bis-PCBM, a mixture of isomers, is primarily utilized in the field of organic electronics, particularly in the development of organic photovoltaic (OPV) devices. Its application is centered around its role as an electron acceptor material in bulk heterojunction solar cells. When blended with electron donor polymers, Bis-PCBM enhances the efficiency of charge separation and electron transport within the active layer of the solar cell, contributing to improved power conversion efficiency. Its structural versatility and ability to form favorable morphologies with donor materials make it a valuable component in the optimization of OPV performance. Additionally, Bis-PCBM is explored in organic field-effect transistors (OFETs) and other organic electronic devices, where its electron-accepting properties are leveraged to improve device functionality and stability.
