Solar cells based on a new type of nanostructure (quantum well-dots) have been studied. These quantum well-dots (QWDs) are In0.4Ga0.6As layers with marked composition and thickness modulations. The energies of the observed optical transitions in QWDs turn out to be close to the energies of transitions involving a light hole and a heavy one in a two-dimensional quantum well of the same nominal thickness and composition. The ground-state peak is characterized by strong TE polarization (>70%), while the shorter-wavelength peak is almost unpolarized (<10%).
