The researchers think organo-lead halide perovskite solar cells&mdash;and their &#8220;record efficiency levels&#8221;&mdash;can lead the next generation of solar cells.<\/p>\n<p>Solar cells have exclusively used organic, hole-conducting polymers that conduct electricity in the cells.&nbsp;Organic polymers are normally more expensive because they are synthetically produced and need to be pure for photovoltaic applications, according to the study.<\/p>\n<p>The researchers replaced an organic polymer with copper iodide, which is cheaper and inorganic. The copper iodide produced power conversion efficiencies as high as 6 percent. Although comparable cells with&nbsp;organic polymers can achieve close to&nbsp;8-percent efficiency,&nbsp;copper iodide could surpass that level with a few refinements to the solar cell, according to the researchers, who published their <a href=\"http:\/\/www.slideshare.net\/kamatlab\/2013-11-13-slideshare-cui\" target=\"_blank\">study<\/a> in&nbsp;the December&nbsp;<a href=\"http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/ja411014k\">Journal of the American Chemical Society<\/a>.<\/p>\n[caption id=\"attachment_319313\" align=\"alignnone\" width=\"500\"]<a href=\"http:\/\/files.cdn.ecowatch.com\/wp-content\/uploads\/2014\/01\/notredamesolar.jpeg\"><img loading=\"lazy\" decoding=\"async\" alt=\"Researchers at the University of Notre Dame believe they have found a less expensive alternative to the organic polymers currently used in solar cells.\" src=\"http:\/\/files.cdn.ecowatch.com\/wp-content\/uploads\/2014\/01\/notredamesolar.jpeg\" width=\"500\" height=\"300\"><\/a> Researchers at the University of Notre Dame believe they have found a less expensive alternative to the organic polymers currently used in solar cells.
