Researchers have demonstrated a new low energy electron beam technique and used it to probe the nanoscale electronic properties of grain boundaries and grain interiors in cadmium telluride (CdTe) solar cells. Their results suggest that controlling material properties near the grain boundaries could provide a path for increasing the efficiency of such solar cells.

If silicon is squeezed, this affects the freedom of movement of the electrons in this material. This can promote or restrict the flow of electrical current. Compare it to a garden hose. When you stand on it, less water comes out. But strangely enough, the flow of electrons in silicon actually increases when the material is compressed.

Read moreResearchers create a nonlinear light-generating zero-index metamaterial
Researchers used a unique optical metamaterial with a refractive index of zero to generate 'phase mismatch-free nonlinear light', meaning the generated light waves move through the material gaining strength in all directions. This phase mismatch-free quality holds promise for quantum computing and networking, and future light sources based on nonlinear optics - the phenomena that occur when interactions with light modify a material's properties.
