Enabling Ideal Selective Solar Absorption with 2D Metallic Dielectric Photonic Crystals. (16th September 2014) - Chou, Jeffrey B.
Abstract A metallic dielectric photonic crystal with solar broadband, omni‐directional, and tunable selective absorption with high temperature stable (1000 °C, 24 hrs) properties is fabricated on a 6" silicon wafer. The broadband absorption is due to a high density of optical cavity modes overlapped with an anti‐reflection coating. Results allow for large‐scale, low cost, and efficient solar‐thermal energy conversion.
