Diero Lassina , Djielbeogo Soumaïla , Diasso Alain , Kam Ollé Michel , Sam Raguilignaba , Zougmoré François
Intermediate-band solar cells require an intermediate electronic manifold that is both confined and sufficiently dispersive to enable sub-bandgap transitions. Here we study a three-dimensional quantum-dot superlattice based on tensile-strained dots embedded in a relaxed matrix, selected to provide electron confinement through the conduction(...)

In recent years, there has been a significant increase in the literature on all-inorganic perovskite solar cells
(PSCs), which are potential candidates for resolving the impasse linked to the high volatility of the organic part
of hybrid perovskites. Among the light absorbers in CsPb1-xSnxIBr2 type, CsPb0.75Sn0.25IBr2 exhibits better film(...)

Comparative study of the electronic properties of hexagonal and orthorhombic structures of RMnO3-type perovskites (R=Tb, Dy, Ho and Er) by DFT calculations
Joël Martial Balkoulga, Antoine Béré, Sidiki Zongo, Viwanou Hounkpati, Moussa Sougoti, Sié Zacharie Kam
The electronic properties of perovskite RMnO3 (R=Tb, Dy, Ho and Er) were studied using the density- functional theory (DFT). For each perovskite RMnO3, the ferromagnetic (FM) and antiferromagnetic (AFM) structural parameters in the spin-up and spin-down configurations are optimized. The band structures, the density of states (DOS) and the part(...)
