Paper Abstract
Semitransparent photovoltaics are of interest for building integration and window coatings, though demonstrate an intrinsic tradeoff between transparency and absorption / efficiency. We propose alleviating this tradeoff using light management nanostructures which selectively scatter light based on incident wavelength and angle, allowing transmission of normally incident light for window visibility and absorption of light at elevated angles. Two structures of interest are proposed and described: metal nanorods which scatter light via their localized surface plasmon resonance properties, and arrays of subwavelength nanopores in a dielectric which demonstrate coherent multiple scattering. Both structures can potentially be patterned over large areas by electrochemical oxidation of aluminum into self assembled nanoporous anodized aluminum oxide (AAO) films.
