Thinned Germanium Substrates for III-V Multijunction Solar Cells
Ivan Lombardero, Naoya Miyashita, Mario Ochoa +2
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 app…
On the Use of Graphene to Improve the Performance of Concentrator III-V Multijunction Solar Cells
Laura Barrutia, IvÁn Lombardero1, Mario Ochoa +6
Graphene has been intensively studied in photovoltaics focusing on emerging solar cells based on thin films, dye-sensitized, quantum dots, nanowires, etc. However, the typical effi…
Impact of the III-V/Ge nucleation routine on the performance of high efficiency multijunction solar cells
Laura Barrutia, Ivan García, Enrique Barrigon +3
This paper addresses the influence of III-V nucleation routines on Ge substrates for the growth of high efficiency multijunction solar cells. Three exemplary nucleation routines wi…
Theoretical and Experimental Assessment of Thinned Germanium Substrates for III-V Multijunction Solar Cells
Iván Lombardero, Mario Ochoa, Naoya Miyashita +2
Solar cells manufactured on top of Ge substrates suffer from inherent drawbacks that hinder or limit their potential. The most deleterious ones are heavy weight, high bulk recombin…
Combined photo- and electroreflectance of multijunction solar cells enabled by subcell electric coupling
D. Fuertes Marrón, E. Barrigón, M. Ochoa +1
Electric coupling between subcells of a monolithically grown multijunction solar cell in short circuit allows their simultaneous and independent characterization by means of photo-…
