Photovoltaic Blend Microstructure for High Efficiency Post-Fullerene Solar Cells. To Tilt or Not To Tilt?

Author(s)
Subhrangsu Mukherjee, Dean M. DeLongchamp, Gang Wang, Steven M. Swick, Micaela Matta, Joseph Strzalka, Thomas Aldrich, Ferdinand Melkonyan, Antonio Facchetti, Tobin Marks, Jenna L. Logsdon, Simone Fabiano, Wei Huang, Tony Yang, Amod Timalsina, Natalia Powers-Riggs, Joaquin Alzola, Ryan M. Young, Michael R. Wasielewski, George C. Schatz
Achieving efficient polymer solar cells (PSCs) requires a structurally optimal donor–acceptor heterojunction morphology. Here we report the combined

X-Ray Nanodiffraction Studies of Ionically Controlled Nanoscale Phase Separation in Cobaltites

Complex oxide heterostructures provide access to emergent functional and structural phases which are not present in the bulk constituent materials. In this

Revisiting the Photon-Drag Effect in Metal Films

Author(s)
Jared H. Strait, Glenn E. Holland, Wenqi Zhu, Cheng Zhang, Bojan R. Ilic, Amit K. Agrawal, Domenico Pacifici, Henri J. Lezec
The photon-drag effect, the rectified current in a medium induced by conservation of momentum of absorbed or redirected light, is a unique probe of the detailed

The hunt for refrigerant blends to replace R-134a

Author(s)
Ian H. Bell, Piotr A. Domanski, Gregory T. Linteris, Mark O. McLinden
We investigated refrigerant blends as possible low GWP (global warming potential) alternatives for R-134a in an air-conditioning application. We carried out an
