ECE Prof. Deli Wang on ScienceLive: Solar Cells Go Nano

Read full text of live chat, on this page: http://news.sciencemag.org/sciencenow/2011/12/live-chat-solar-cells-go-nano.html
Find out how two new technologies (the first produces solar cells from plastics and other organic compounds; the second uses tiny inorganic nanoscale wires to capture the sun's energy) capture sunlight, how scientists use nanotechnology to create these cells, and how they can help solar panels churn out more power for less money.
