Germanium is an important material for today''s highest efficiency solar cells with three np-junctions based on GaInP, GaInAs and Ge. The Ge subcell in these structures consists of a 100–300 nm thin diffused n-type emitter passivated with GaAs or GaInP and a 150 μm thick base layer which is not passivated. Therefore, the current generation of the Ge subcell mainly …
Multijunction solar cells are usually grown on Ge substrates. This implies several disadvantages that hinder the performance of the whole multijunction and limit their possible applications. The drawbacks caused by the substrate are: heavier devices, higher operation temperatures, lower performance and lack of photon confinement. In this work we propose thinning the substrate …
As one of the critical raw materials the use of it (mainly driven by solar cells) is a major contributor to mineral resource depletion. Today, Germanium is used as a growth template for certain solar cells. While the thickness of the Germanium on a solar cell level is extremely thin, around 140μm, actually only 10-20μm are actively being used.
