ScienceDaily: “Organic photovoltaic (OPV) cells have been proposed as a means to achieve low cost energy due to their ease of manufacture, light weight, and compatibility with flexible substrates,” wrote Chongwu Zhou, a professor of electrical engineering in the USC Viterbi School of Engineering, in a paper recently published in the journal ACS Nano. The technique described in the article describes progress toward a novel OPV cell design that has significant advantages, particularly in the area of …
