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…
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…
Point-defects assisted Zn-diffusion in AlGaInP/GaInP systems during the MOVPE growth of inverted multijunction solar cells
Manuel Hinojosa, Iván García, Shabnam Dadgostar +1
We investigate the dynamics of Zn diffusion in MOVPE-grown AlGaInP/GaInP systems by the comparison of different structures that emulate the back-surface field (BSF) and base layers…
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…
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…
