But that's not all the article said; it isn't just more surface area, but with plasmonics tuned so that electrical resistance is lower and the maximum number of electrons can get knocked loose by a photon.
Don't expect a physics class in a magazine article, but for someone not in the field wikipedia will do. I looked up plasmonics before reading the article and it made the article a lot more informative.
