Photovoltaic spectra of InGaAs/GaAs multiple quantum wells grown by metalorganic vapor phase epitaxy show several well defined spectral structures which are interpreted in terms of the sample characteristics. Results obtained by this relatively simple method are comparable to data obtained by other optical techniques on the same material, and in good agreement with calculations taking into account the strain-induced splitting and the coupling between the wells.
