Etude de stabilité des pérovskites aux halogénures mixtes plombate de Formamidinium FAPbX3 avec X={ Cl,Br,I}

Abdoulaye, Touré (Universitat Politècnica de València, 2024-03-17)

[FR] L'énergie photovoltaïque se présente comme une solution primordiale dans la lutte contre le réchauffement climatique. Malgré la maturité et la fiabilité de la technologie des cellules en silicium cristallin, les ...
Recent results for single-junction and tandem quantum well solar cells

Adams, J.G.J.; Browne, B.C.; Ballard, I.M.; Connolly, James Patrick; Chan, N.L.A.; Ioannides, A.; Elder, W.; Stavrinou, P.N.; Banham, J.W.J.; Ekins-Daukes, N.J. (Wiley, 2011-11)

[EN] The band gap of the quantum well (QW) solar cell can be adapted to the incident spectral conditions by tailoring the QW depth. The single-junction strain-balanced quantum well solar cell (SB-QWSC) has achieved an ...
Simultaneous guidance of slow photons and slow acoustic phonons in silicon phoxonic crystal slabs

Laude, Vincent; Beugnot, J.C.; Benchabane, S.; Pennec, Y.; Djafari-Rouhani, B.; Papanikolaou, Nikos; Escalante Fernández, José María; Martínez Abietar, Alejandro José (Optical Society of America, 2011)

[EN] We demonstrate theoretically that photons and acoustic phonons can be simultaneously guided and slowed down in specially designed nanostructures. Phoxonic crystal waveguides presenting simultaneous phononic and photonic ...
Theoretical study about the gain in indirect bandgap semiconductor optical cavities

Escalante Fernández, José María; Martínez Abietar, Alejandro José (Elsevier, 2012-06-15)

[EN] Indirect bandgap semiconductors such as silicon are not efficient light emitters because a phonon with a high momentum is required to transfer an electron from the conduction to the valence band. In a recent study ...
