Learn MoreSolar cell systems don''t use chemical reactions and don''t need fuel, unlike batteries. Solar cells don''t have any moving parts, unlike electric generators. Domestic solar cells generate power from about 20% of the sunlight they receive, although more expensive commercial solar systems can generate up to 40%.
Learn MoreSolution processing requires considerably less energy than the heat-intensive process used to make silicon solar cells. It leads to the formation of thin films of polymers that can be...
Learn MoreThe first demonstration of the photovoltaic effect, by Edmond Becquerel in 1839, used an electrochemical cell. He explained his discovery in Comptes rendus de l''Académie des sciences, "the production of an electric current when two plates of platinum or gold immersed in an acid, neutral, or alkaline solution are exposed in an uneven way to solar radiation."
Learn MoreWhy goats? Because both spiders'' silk glands and goats'' mammary glands contain cells that make similar types of complex proteins that can be dissolved in water, according to New Scientist. Turner hoped that the spider-silk proteins would turn up in the milk of the genetically-modified goats. The company then planned to use the milked …
