Abstract :
Intersubband transitions in quantum cascade heterostructures have been proposed for thermo-photovoltaic energy conversion for applications in solar cells so that when they are used cascaded with p-n junctions efficiency can be increased. Our designed structures produce wider absorption spectra and faster carrier transport than those have been reported before.
