Solar panels made 40 percent more efficient

A new silicon coating for solar panels boosts their sunlight absorption from 67 to 96 percent. The new, anti-reflective coating also makes it easier to capture sunlight from all angles, which means solar cells can now be placed on sites that don’t generally face south.

Price? Not expected to add more than 2-4 percent to current solar cell costs, according to the scientific developers of the nanotech coating.
