摘要: Thermalization loss in a structure of solar cell where an intermediate band (IB) is introduced by embedding stack hexagonal In x Ga l-x As quantum wires (QW) the intrinsic layer p-i-n GaAs calculated theoretical framework based on principle detailed balance approach. To obtain position IB, finite element method used for solving Schrodinger equation to calculate possible energy configurations GaAs: barrier/ As: QW. Then, effect indium content QWs, size and period QWs thermalization investigated. The results show that there fundamental limitation ~35% achieving ultra-high efficiency QW-IBSCs.
