Future terrestrial concentrator cells will likely feature four or more junctions. The better division of the solar spectrum and the lower current densities in these new multijunction cells reduce the resistive power loss (I^(2)R) and provide a signif

Spectrolab has achieved a record 36% 5J direct bonded cell, measured under an AM0 space spectrum. The increase in efficiency over previous high performance 5J cells was achieved via voltage improvements to subcell 2 and 4 of the multijunction stack.
