Interplay of Electron Trapping by Defect Midgap State and Quantum Confinement to Optimize Hot Carrier Effect in a Nanowire Structure
Imam Makhfudz, Hamidreza Esmaielpour, Yaser Hajati +2
Hot carrier effect, a phenomenon where charge carriers generated by photon absorption remain energetic by not losing much energy, has been one of the leading strategies in increasi…
Coherent Phonons-Driven Hot Carrier Effect in a Superlattice Solar Cell
Imam Makhfudz, Nicolas Cavassilas, Yaser Hajati +2
Carrier thermalization in a superlattice solar cell made of polar semiconductors is studied theoretically by considering a minimal model where electron-phonon scattering is the pri…
Enhancement of Hot Carrier Effects and Signatures of Confinement in Terms of Thermalization Power in Quantum Well Solar Cells
Imam Makhfudz, Nicolas Cavassilas, Maxime Giteau +4
A theoretical model using electron-phonon scattering rate equations is developed for assessing carrier thermalization under steady-state conditions in two-dimensional systems. The…
Impact of electron-phonon scattering on optical properties of CHNHPbI hybrid perovskite material
Benoit Galvani, Daniel Suchet, Amaury Delamarre +5
We investigate numerically the impact of the electron-phonon scattering on the optical properties of a perovskite material (CH3NH3PbI3). Using non-equilibrium Green functions forma…
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…
Dynamical photo-induced electronic properties of molecular junctions
K. Beltako, F. Michelini, N. Cavassilas +1
Nanoscale molecular-electronic devices and machines are emerging as promising functional elements, naturally flexible and efficient, for next generation technologies. A deeper unde…
Improvement of current-control induced by oxide crenel in very short field-effect-transistor
Nicolas Cavassilas, Marc Bescond, Jean-Luc Autran
A 2D quantum ballistic transport model based on the non-equilibrium Green's function formalism has been used to theoretically investigate the effects induced by an oxide crenel in…
