UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishInspired by the apposition compound eyes of some dipterans, we analyzed the eect of texturing the exposed face of a silicon solar cell by ray-tracing simulation. Bioinspired textures of two types were considered: hillock textures and pit textures. A multifrequency analysis|that took into account the broadband nature of solar radiation and its amplitude at the sea-level, as well as the wavelength dependence of the complex-valued refractive index of silicon|showed that both types of bioinspired textures are benecial. We found that the light-coupling eciency can be enhanced by as much as 20% and 24% with respect to that of a at surface when the exposed face of a silicon solar cell is decorated with the bioinspired hillock texture and the bioinspired pit texture, respectively.
