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…
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…
Inverted rear-heterojunction GaInP solar cells using Te memory effect
Manuel Hinojosa, Iván García, Ignacio Rey-Stolle +1
Tellurium allows attaining heavy n-type doping levels in GaAs, which is suited to achieve very low contact resistivities in solar cells. Besides, it modifies the energy bandgap of…
