This thesis presents a study of cadmium telluride /germanium tandem solar cells. Numerical simulation of these devices is used to explore potential efficiency gains. A technology for doping, passivation, and contacting germanium devices was developed and stand alone germanium solar cells of 5.4% efficiency were demonstrated. Cadmium telluride thin films were grown on germanium and sapphire substrates with double crystal rocking curve full width at half maxima as low as 59 arc seconds. A CdTe / Ge heterojunction was fabricated and IV and CV profiling yielded insight into the electronic properties of this novel combination of materials.
