“Beyond the Lambertian Light-Trapping Limit: Quasi-Resonant Absorption for Enhanced and Robust Thin-Film Silicon Photovoltaics”

Ardavan Oskooi  氏

The maximum absorption of solar radiation over the broadest range of frequencies and incident angles using the thinnest material possible has important applications for renewable-energy generation. Complete random texturing of the film surface to isotropically scatter incident light rays into the plane of the absorbing film so as to increase the optical path length, first proposed nearly thirty years ago by Eli Yablonovitch, has thus far remained the most effective approach for photon absorption over the widest set of conditions. Recent nanostructured designs involving resonant wave effects of photons have explored the possibility of superior performance though as of yet no proposal satisfying the dual requirements of enhanced and robust absorption over a large fraction of the solar spectrum has been made. In this seminar I will describe a new mechanism for the absorption of photons based on quasi resonances and describe a general design strategy as well as present experimental results for a thin-film silicon photovoltaic cell consisting of a partially-disordered photonic-crystal thin film that surpasses the Lambertian limit over a wide range of conditions.
