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…
Resonant absorption in multilayer quantum-well and quantum-dot solar cells
Maxime Giteau, Yusuke Oteki, Kento Kitahara +3
Epitaxially-grown quantum well and quantum dot solar cells suffer from weak light absorption, strongly limiting their performance. Light trapping based on optical resonances is par…
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…
Voltage preservation in Intermediate Band Solar Cells
Daniel Suchet, Amaury Delamarre, Nicolas Cavassilas +4
Intermediate Band Solar Cell is an advanced concept for solar energy conversion in which two low-energy photons can promote an electron to the conduction band through a so-called i…
Beneficial impact of tunneling in nano-structured intermediate-band solar cell
Nicolas Cavassilas, Daniel Suchet, Amaury Delamarre +5
Using the non equilibrium Green functions formalism we propose a study of the electronic excitation and collection in nano-structured intermediate-band solar cell. We demonstrate t…
An electronic ratchet is required in nanostructured intermediate band solar cells
Amaury Delamarre, Daniel Suchet, Nicolas Cavassilas +3
We investigate in this letter the intrinsic properties that have limited the efficiency of nanostructured intermediate band solar cells. Those devices take advantage of intra-band…
Hot Carrier Transportation Dynamics in InAs/GaAs Quantum Dot Solar Cell
Tomah Sogabe, Kohdai Nii, Katsuyoshi Sakamoto +2
The hot carrier dynamics and its effect on the device performance of GaAs solar cell and InAs/GaAs quantum dot solar cell (QDSC) was investigated. At first, the fundamental operati…
