Abstract
We have developed a method to design multi-junction horizontally-oriented solar cells using single-layer photonic metamaterials. These metamaterial light harvesting templates are capable of separating white light into discrete wavelength ranges and trapping it efficiently into different, separately wired cavities. Any number of different wavelength-tailored charge separation complexes can be fixed to the walls of these tuned cavities. To design the metamaterials we have developed a coupled wave analysis of 2D periodic metamaterials. Past results with 1D gratings have shown that this is a very effective method for designing periodic structures and we have generalized the approach to 2D periodic cavities.
