At the and of every solar cell producer′s road map is the IBC solar cell concept.However,in order to come there from standard production,several things have to be changed in the solar cell line.This presentation will show the status of IBC solar cells in production and in R&D and in addition show how simple such an upgrade of existing solar cell lines could work,on the example of the ZEBRA technology.At the end an outlook will be given,how future solar cells could look like,if the Si cell in production reaches its theoretical limit.
