A stacked multijunction solar cell having a dielectric insulating layer system, a germanium substrate, which forms an underside of the multijunction solar cell, a germanium subcell and at least two III-V subcells, which follow each other in the specified order, the insulating layer system includes a layer sequence made up of at least one bottom insulating layer, which is integrally connected to a first surface section of the multijunction solar cell and a top insulating layer forming an upper side of the insulating layer system, and a metal coating of the multijunction solar cell is integrally and electrically conductively connected to a second surface section abutting the first surface section of the multijunction solar cell and is integrally connected to a section of the upper side of the insulating layer system, and the top insulating layer comprises amorphous silicon or is made up of amorphous silicon.

Stacked multijunction solar cell having a dielectric insulating layer system

A method including: providing a structure comprising: a spalled layer having a first side and a second side; and a tape layer provided on the first side of the spalled layer, wherein the tape layer is provided at below a first temperature range; applying a temporary substrate layer to the second side of the spalled layer, wherein the temporary substrate layer is applied at a second temperature range, and wherein at least a portion of the second temperature range is lower than the first temperature range; and after applying the temporary substrate layer, separating the tape layer from the spalled layer.
