A Refined Ideal Model for AlGaAs/GaAs Quantum Well Solar Cells
نویسندگان
چکیده
Quantum well solar cells are heterostructure devices promising significant efficiency enhancements over conventional cells. An existing model for quantum well solar cell current-voltage characteristics has been refined. This refined model, unlike its predecessor, is in good agreement with previous experimental results for AlGaAs/GaAs. The model predicts some efficiency enhancements for quantum well solar cells if non-radiative recombination is dominant—when in the detailed balance limit there would be none—even in such a poor quantum well solar cell material as AlGaAs/GaAs.

A revised ideal model for AlGaAs/GaAs quantum well solar cells
Quantum well solar cells (QWSCs) are heterostructure devices intended to achieve higher efficiencies than conventional cells. This paper extends a previous model for QWSC current–voltage characteristics by revising the equations for the absorbed flux and by introducing expressions to calculate radiative recombination coefficients and well effective densities-of-states. This revised model is in ...

We have studied the effects of AlGaAs energy barriers surrounding self-assembled InAs quantum dots in a GaAs matrix on the properties of solar cells made with multiple quantum dot layers in the active region of a photodiode. We have compared the fenced dot samples with conventional InAs/ GaAs quantum dot solar cells and with GaAs reference cells. We have found that, contrary to theoretical pred...
متن کاملUltrahigh spontaneous emission quantum efficiency, 99.7% internally and 72% externally, from AIGaAs/GaAs/ AlGaAs double heterostructures
Optically thin AlGaAs/GaAs/AlGaAs double heterostructures, (5000 A), are floated off their substrates by the epitaxial liftoff technique and mounted on various high reflectivity surfaces. From the absolute photoluminescence intensity, we measure internal and external quantum efficiencies of 99.7% and 72%, respectively. High spontaneous emission quantum efficiency, is important for photon number...
متن کاملThe Effect of Global Solar Variations on the Performance of n-AlGaAs/p-GaAs Solar Cells
This study investigates how AlGaAs/GaAs thin film solar cells perform under varying global solar spectrum due to the changes of environmental parameters such as the air mass and the atmospheric turbidity. The solar irradiance striking the solar cell is simulated using the spectral irradiance model SMARTS2 (Simple Model of the Atmospheric Radiative Transfer of Sunshine) for clear skies on the si...
