Abstract
A monolithic, tandem photovoltaic device is provided having an indium gallium arsenide tunnel junction lattice-matched to adjoining subcells and having high peak current densities and low electrical resistance. A method is provided for relatively low-temperature epitaxial growth of a subcell over the tunnel junction at temperatures which leave intact the desirable characteristics of the tunnel junction.
