Noncentrosymmetry (NCS) is a requirement for many properties such as piezoelectricity, pyroelectricity, and nonlinear optical activity like second harmonic generation which are desirable for a variety of commercial applications. One method which has been employed to successfully synthesize NCS compounds utilizes acentric anionic groups, such as oxyfluoride metal complexes, as...
Organic photovoltaic (OPV) solar cells aim to provide efficient, flexible and lightweight photovoltaics (PV) with simple processing and low-cost. Advances in device optimization, structural and molecular design, as well as mechanistic understanding have helped increase device efficiency and performance. Within the framework of active layer optimization, systematically improving bulk heterojunction...
