摘要
Structures consisting of a single layer of silicon quantum dots in silicon dioxide matrix represent a promising approach to implement energy selective contacts for hot carrier solar cells. The opening of the band gap and the resonant tunneling effect allow extraction of carriers within a narrow tunable range of energies. In this work, several silicon quantum dots double barrier structures have been realized using RF-magnetron co-sputtering. Quantum confinement properties of silicon quantum dots and the influence of the annealing process duration on crystallization have been investigated using photoluminescence measurements.
