Innovative Solar Cell R&D Project Supported by New Energy and Industrial Technology Development Organization (NEDO)

Reseach and Development of Post-Sillicon Solar Cells for Ultra-High Efficiencies


Started on 2008
Director :Distinguished Professor Masafumi Yamaguchi

Research Outline

Solar photovoltaic power generation is expected to share with 20% and 70% in total energy in the world until 2050 and 2100, respectively. In this project, research and development on concentrator multi-junction solar cells will be carried out in order to realize world record efficiency of more than 48%. As a result of research and development in this project, creation of new clean energy necessary for solving environmental and energy problems is expected.
