A team of researchers from the Fraunhofer Institute (ISE, Freiburg) and AMOLF (Amsterdam) have broken the world record for efficiency in silicon-based multijunction solar cells; with 36.1% this is the highest efficiency ever reached for this type (upwards from 27% for conventional silicon solar cells).

Using the soft-imprint technique using rubber stamps developed by SCIL Nanoimprint Solutions to fabricate the nanopatterned backcontact over the full area of the solar cell. This enables better trapping of light inside the solar cells and therefore increasing efficiency beyond 36%.
