Status of C3MJ+ and C4MJ Production Concentrator Solar Cells at Spectrolab

Multijunction solar cells based on III-V semiconductors, having recently demonstrated 43.5%, remain the world's most efficient solar cells, and the preferred technology in point-focus and dense-array concentrator photovoltaic (CPV) system architectures. The year 2011 proved to be a pivotal year for CPV technology, with multiple power plant installations in the megawatt to tens of megawatt scale. S...
