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…
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…
