Zusammenfassung:This application is related to a method of manufacturing a solar cell device comprising providing a substrate comprising Ge or GaAs; forming a first tunnel junction on the substrate, wherein the first tunnel junction comprises a first n-type layer comprising InGaP:Te, and a first alloy layer comprising AlxGa(1−x)As and having a lattice constant; adding a material into the first alloy layer to change the lattice constant; and forming a first p-n junction on the first tunnel junction.
