The external quantum efficiency (EQE) of a high efficiency lattice matched multi-junction solar cell (MJSC) and a quantum dot enhanced MJSC are numerically simulated. An effective medium is developed and integrated into the model to simulate the absorption characteristics of the quantum dots in the latter device. A calibration of the model is carried out using room temperature EQE measurements of...
Multi-junction solar cells (MJSC) under concentrated sunlight are leading the way forward to record efficiencies (>;40%, under AM1.5D solar spectrums) and are ideally suited for utility-scale energy production. MJSC are able to achieve high efficiencies by partitioning the solar spectrum using multiple n-p junctions composed of III-V and IV group semiconductors. To reduce the cost associated with...
