Analysis and fabrication of antireflective coating for photovoltaics based on a photonic-crystal concept and generated by evolutionary optimization

We optimize multilayered antireflective coatings for photovoltaic devices, using modern evolutionary algorithms. apply a rigorous methodology to show that given structure, which is particularly regular (i.e., essentially periodic), emerges spontaneously and systematically very broad range of conditions. The regularity the structure allows thorough physical analysis how design operates. This us understand central part photonic crystal utilized as buffer light, external layers have purpose reducing impedance mismatch between outer media Bloch mode supported by crystal. shows optimization can suggest new rules be considered source inspiration. Finally, we fabricate these structures with easily deployable techniques.
