Solar Cells That Work All Day

April 17, 2007 | Source: Technology Review

Georgia Tech Research Institute researchers have developed solar cells designed to operate at relatively high efficiencies during much of the day.

Its surface consists of hundreds of thousands of 100-micrometer-high towers that catch light at many angles.

A first application is powering spacecraft and satellites, which could benefit from solar cells that don’t require a failure-prone mechanical means of moving the orientation of the cell to keep it facing the sun.
