Solar Frontier has achieved a world record thin - film solar cell efficiency of 22.9 % , the manufacturer said . The result , achieved on a 1000 sq cm cell , was 0.3 % higher than a previous record set by German research center ZSW and verified by Japan 's national Institute of Advanced Industrial Science and Technology . The cell used copper , zinc and selenium ( CIS ) technology with improvements from " absorber engineering and enhanced surface treatment of the silicon layer " , Solar Frontier said . It was developed in partnership with Japan 's National Research and Development Agency 's New Energy and Industrial Technology Development Organisation .
