Leaner and Cheaper

In its October 24 issue, The Economist has introduced its readers to thin-film solar technology. Beginning with a winning entry for this year’s Solar Decathlon, the brief article takes a peek at growing efficiencies in thin-film solar solutions (as contrasted with traditional crystalline arrays) and the growing cost-competitiveness of these materials in larger power schemes. Companies such as Dow (which has introduced solar-energy shingles), First Solar, and Nanosolar are mentioned.
