A novel solar cell utilizing guided optical waves and tunnel junctions has been analyzed to determine its feasibility. From this analysis, it appears that the limits imposed upon conventional multiple cell systems also limit this novel solar cell. Due to this limitation, it appears that the relative simplicity of the conventional multiple cell systems over the novel solar cell make the conventional multiple cell systems the more promising candidate for improvement. In the course of this investigation, it was discovered that some superlattice structures studied could be incorporated into an infrared photodetector. This photoconductor appears to be promising as a high speed, sensitive (high DBLip) detector in the wavelength range from 15 μm to over 100 μm.
