WebDec 2, 2008 · We present simulations of the optical properties of 1D and 3D photonic structures and how 3D structures are realized with colloidal opals. We also show that the application of a 1D photonic structure increases the efficiency of a real system by 20% relative. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) WebOne of the keys towards high efficiency thermophotovoltaic (TPV) energy conversion systems lies in spectral control. Here, we present detailed performance predictions of …
