Production of Flexible Transparent Conducting Films of Self-Fused Nanowires via ...
Launching silver nanowire suspension water out of a supersonic nozzle at a specific speed allows creating a transparent thin film mat on a surface, that fuses/evaporates on impact. The resulting thin film is transparent, conductive, and stretchable.

Enhanced photovoltaics inspired by the fovea centralis : Scientific Reports : Nature Publishing Group
Interesting nanostructure research to improve solar cell efficiency by improving light capture. The takeaway is that straight right cylinder nanowires actually perform worse than nanowires with uneven shapes, one extreme being a nanofunnel (wouldn't this be more like a cone or frustrum though?)

3-D photovoltaic systems go where the sun don’t shine
If each individual nanowire is in essence a receiver cell, then upping collector power is a function of lengthening the fiber (which has no bearing on solar planar catch area, basically you make the true collector thicker), right?...
