The team\u2019s paper is published in <em>Nature Communications<\/em>.<\/p>\n<p>While some of today\u2019s solar cells use a blend of cadmium and tellurium to convert light into electricity, adding the optimum amount of selenium in the right places could help increase efficiency from the current mark of about 22 percent to levels approaching the theoretical limit of 30\u201333 percent. The trick is to determine the best ratio of selenium.<\/p>\n<p>\u201cUsing different microscopy methods, we were able to gain a better understanding of the phases, compositions and crystalline structures that allow these materials to convert light into electricity more efficiently,\u201d said Poplawsky, adding that the availability of data is limited. \u201cIn some instances, adding too much selenium changes the crystalline structure of cadmium-tellurium and dramatically reduces the conversion efficiency.\u201d<\/p>\n<p><!-- Link: <a href=\"http:\/\/scienmag.com\/ornl-optimizes-formula-for-cadmium-tellurium-solar-cells\/\">http:\/\/scienmag.com\/ornl-optimizes-formula-for-cadmium-tellurium-solar-cells\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nice and Kudos to ORNL.
