The 3D optimized structure based on simulation with triangles and mirrors for concentration shown in Figure 3b,c is weird. Too bad solar cells aren't normally made as triangles, but as rectangles or squares. Seems the simple tower type that looks like waffle cut fries may be the easiest to make though.

How 3-D Photovoltaics Could Revolutionize Solar Power - Technology Review
Hrm, 9 panel cube is roughly 4 times better than equivalent non-tracking 2D flat panel at a fixed angle. But comparing the equivalent area monolithic flat 2D fixed panel, it is only 2 times better. For reference, the original footprint using a 2D panel with tracking is 1.8 times better. So, for roughly double the installed $/KW, you can reduce your footprint by 3/4. So this works for area restricted installations. Whether the performance numbers are real for cloudy days at non-optimal angles as well as the alleged increase in peak hour ops is a concern.

100 (Hundred) Year Starship Study
DARPA project to pioneer tech for enclosed generational starships. SO this deals with things like recycling, 3D printing, closed biomes and life support systems, etc.

Slideshow: Solar power, shaped up
Oddball self intersecting 3D solar panel rigs that are non-moving appear to have comparable efficiency to flat solar panels with sun tracking systems. How would you go about manufacturing these shapes is a bit of an issue 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?...
