Bloo! It's 3-D solar cells

Can tiny, efficient 3-D solar cells scare solar opponents?

Tiny nano-scale bristles could be the key to efficient, cost-effective solar power, according to Bloo Solar, because these bristles enable better light absorption.

GreenTech reports, "The 3-D nature of the bristles also means that it can harvest light during the early and late hours of the day, something planar solar cells can struggle with. Bloo in some ways is combining a number of trends into a single product: the popularity of cad tel, reducing the cost of thin-film solar cells, using 3D structures to extend the active time of solar cells like Solyndra and better light trapping."
