Researchers at the University of California, San Diego have come up with a way of making solar photovoltaic cells more efficient by making them fuzzy with nanowires.
Boosting solar cell efficiency The idea is [to] use nanowires to more efficiently conduct electrons from the collection surface of the solar cell to an electrode. Contemporary thin-film solar cells provide no direct conduit for electron travel.If the process scales well, it has the potential to dramatically improve the efficiency of next-generation solar photovoltaic panels.
Hairy Solar Cells Could Mean Higher Efficiency
This picture is actually GaN nanowires grown by molecular beam epitaxy (MBE) at the National Institute of Standards and Technology (NIST.)
