Abstract
A multijunction silicon solar cell of high efficiency is provided by providing a tunnel junction between the solar cell junctions to connect them in series, where the tunnel junction is comprised of p.sup.+ and n.sup.+ layers of high band-gap III-V or II-VI semiconductor materials that match the lattice structure of silicon, such as GaP (band-gap 2.24 eV) or ZnS (band-gap 3.6 eV), each of which has a perfect lattice match with silicon to avoid defects normally associated with lattice mismatch.
