Sharp develops solar cell with the conversion efficiency of 37.9%
Sharp Corporation has achieved the world's highest solar cell conversion efficiency of 37.9% using a triple-junction compound solar cell in which three photo-absorption layers are stacked together.
Sharp achieved this latest breakthrough as a result of a research and development initiative promoted by Japan’s New Energy and Industrial Technology Development Organization (NEDO) on the theme of "R&D on Innovative Solar Cells." Measurement of the value of 37.9%, which sets a new record for the world's highest conversion efficiency, was confirmed at the National Institute of Advanced Industrial Science and Technology (AIST).
