Improved GaInP/GaAs/GaInAs inverted metamorphic triple-junction solar cells by reduction of Zn diffusion in the top subcell
Manuel Hinojosa, Ivan Lombardero, Carlos Algora +1
The growth of heavily doped tunnel junctions in inverted metamorphic multijunction solar cells induces a strong diffusion of Zn via a point-defects-assisted mechanism. The redistri…
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…
Temperature Accelerated Life Test and Failure Analysis on Upright Metamorphic Ga0.37In0.63P/Ga0.83In0.17As/Ge Triple Junction Solar Cells
Vincenzo Orlando, Iván Lombardero, Mercedes Gabás +6
A temperature accelerated life test on Upright Metamorphic Ga0.37In0.63P/Ga0.83In0.17As/Ge triple-junction solar cells has been carried out. The acceleration has been accomplished…
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…
Ge virtual substrates for high efficiency III-V solar cells: applications, potential and challenges
Iván García, Manuel Hinojosa, Iván Lombardero +7
Virtual substrates based on thin Ge layers on Si by direct deposition have achieved high quality recently. Their application to high efficiency III-V solar cells is analyzed in thi…
