Design of organic ternary blends and small-molecule bulk heterojunctions: photophysical considerations

Creator:

Rajesh, Kallarakkal Ramakrishnan, Paudel, Keshab, Johnson, Brian, Hallani, Rawad, Anthony, John, and Ostroverkhova, Oksana

Abstract:

We explored relationships between photophysical processes and solar cell characteristics in solution-processable bulk heterojunctions (BHJs), in particular: (1) polymer donor:fullerene acceptor:small-molecule (SM) nonfullerene acceptor, (2) polymer donor:SM donor:SM nonfullerene acceptor, and (3) SM donor:SM nonfullerene or fullerene acceptor. Addition of a nonfullerene SM acceptor to “efficient” polymer:fullerene BHJs led to...

Energy and heat fluxes due to vertically propagating Yanai waves observed in the equatorial Indian Ocean

Creator:

Smyth, W. D., Durland, T. S., and Moum, J. N.

Abstract:

Shipboard current measurements in the equatorial Indian Ocean in October and November of 2011 revealed oscillations in the meridional velocity with amplitude ~0.10 m/s. These were clearest in a layer extending from ~300 to 600 m depth and had periods near 3 weeks. Phase propagation was upward. Measurements from two...
