Work Package 3 - July 2018

Objectives and Status

In work package 3 different Silicon bottom solar cell concepts are currently investigated. One main focus is the implementation of novel rear side light trapping structures,  including their integration in production processes.  The focus ison photonic metal gratings and tailored diffusors.  Additionally, the full Silicon bottom cell is optimised for the use in tandem devices.
