cost-competitive with other energy sources.\u00a0 <!--more-->First, researchers in Switzerland have managed to increase the efficiency record for flexible cells made from copper indium gallium selenide (CIGS) from 17.6 percent to 18.7 percent.\u00a0 While that may seem like a minor upgrade, it\u2019s up from 14.1 percent as recently as 2005.\u00a0 Gian-Luca Bona, the director of Empa, the Swiss Federal Laboratories for Materials and Technology, said, &#8220;Next, we need to transfer these innovations to industry for large scale production of low-cost solar modules to take off.&#8221; Empa is working with a Swiss startup called Flison to bring the thin-film solar cells to market.\u00a0 Second, researchers at the University of Missouri, United States, have used what they call \u201cnantenna\u201d to create a flexible solar design that theoretically could achieve 95 percent conversion efficiency.\u00a0 While still in the very early stages of development, a Missouri associate professor of chemical engineering said, &#8220;If successful, this product will put us orders of magnitudes ahead of the current solar energy technologies we have available to us today.\u201d<\/p>\n<p><a
