Weak Signal's description 
Chemists have perfected a simple way to manufacture inexpensive copper nanowires in great quantities that are so small they are transparent. Applications could clearly be in thin-film solar cells, TVs, computers and other flexible displays. Copper can be used to make a film of nanowires that is both transparent and conductive and this is a material that is abundant in the earth's crust and doesn't take much energy to extract. Silver nanowires also perform well as a transparent conductor, but silver is rare and expensive. Attempts have been made to improve the performance of carbon nanotubes as a transparent conductor, but without much luck, and the fact that copper nanowires are cheaper and work better makes them a very promising material to solve this problem.
