摘要

Dual-mirror aplanatic optics - recently developed for concentrator photovoltaics - can offer efficient, ultra-compact, high-irradiance solar concentration. However, intrinsic limitations site the focus inside the concentrator and hence engender a dielectric terminal concentrator to deliver the concentrated radiation to the photovoltaic cell outside the optic, with the associated requirement of an optical bond to the cell. Can a modification in the design strategy place the focus outside the optic - and hence obviate the need for a terminal concentrator and optical bond - without compromising compactness, low shading losses, or even the practical virtue of the primary and secondary mirrors being coplanar toward easing optical component alignment? We show how nested dual-mirror aplanats can satisfy all these goals, supported by ray trace performance evaluations.
