Sharp Achieves 25.1% Efficiency With Crystalline Si Solar Cell

Sharp Achieves 25.1% Efficiency With Crystalline Si Solar Cell Apr 28, 2014 15:39 Motonobu Kawai, Nikkei Electronics Sharp Corp announced that it has achieved a cell conversion efficiency of 25.1% with a crystalline silicon (Si) solar cell. The efficiency is the second highest after the 25.6% efficiency that Panasonic Corp announced April 10, 2014. For a long period of time, the highest efficiency for a crystalline Si solar cell had been 25.0%, which the University of New South Wales (UNSW) in Australia achieved in March 1999. This time, Panasonic and Sharp broke the record at almost the same time. Like Panasonic, Sharp used a cell combining the "heterojunction," which is made by forming an amorphous Si layer on a Si substrate, " and the "back contact structure," which forms electrodes only on the reverse side. The amorphous Si layer prevents carrier recombination on the s...
