Hybrid III-V/SiGe solar cells on Si substrates and porous Si substrates
Pablo Caño, Manuel Hinojosa, Luis Cifuentes +6
A tandem GaAsP/SiGe solar cell has been developed employing group-IV reverse buffer layers grown on silicon substrates with a subsurface porous layer. Reverse buffer layers facilit…
Evidence of enhanced Zn-diffusion observed during the growth of Inverted Metamorphic Solar Cells
Manuel Hinojosa, Ivan Garcia, Ignacio Rey-Stolle +1
Zinc-diffusion can induce multiple failures in the electrical performance of a multijunction solar cell. In this work, we show an important Zn-diffusion from the AlGaInP back-surfa…
Thinned GaInP/GaInAs/Ge solar cells grown with reduced cracking on Ge|Si virtual substrates
Ivan García, Laura Barrutia, Shabnam Dadgostar +3
Reducing the formation of cracks during growth of GaInP/GaInAs/Ge 3-junction solar cells on Ge|Si virtual substrates has been attempted by thinning the structure, namely the Ge bot…
High-Low Refractive Index Stacks for Broadband Antireflection Coatings for Multijunction Solar Cells
GuoJiao Hou, Iván García, Ignacio Rey-Stolle
Antireflection coatings are an interesting challenge for multijunction solar cells due to their broadband spectrum absorption and the requirement of current matching of each subcel…
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…
