A new approach to increasing solar-cell panel efficiency using an “invisibility cloak” has been developed by scientists at Karlsruhe Institute of Technology (KIT) in Germany.
Up to one tenth of the surface area of solar cells is typically covered by “contact fingers” that extract current generated by solar cells. The fingers block some of the light from the active area of the solar cell, decreasing cell efficiency. By guiding… read more
