Nonimaging Optics: Efficient Design for Illumination and Solar Concentration XVI.
The pragmatic virtues of ground-level receivers in solar towers have long been recognized, but the associated beam-down optics reduce concentration, resulting in higher heat loss and cost, or the need for an actively-cooled tertiary concentrator that

Heat losses from line focus solar collectors, such as parabolic troughs and Linear Fresnel Reflectors (LFR), are reduced by using selectively coated vacuum heat collector elements (HCE). The main parameters governing convective and radiative heat los

Illumination Optics V.
Aplanatic optics were invented over a century ago, motivated principally to achieve high-fidelity imaging in telescopes, microscopes and cameras. Aplanats are designed to completely eliminate the two leading orders of geometric aberration - spherical

Aplanats refer to inherently imaging optics that wholly eliminate both spherical aberration and coma. They typically comprise two refractive and/or reflective surfaces. For radiative transfer (which is typically nonimaging in nature), aplanats can cl

In this study we employ Life-Cycle Assessment to evaluate the energy-related impacts of photovoltaic systems at different scales of integration, in an arid region with especially high solar irradiation. Based on the electrical output and embodied ene

Developing continuous-flow high-temperature fabrication strategies constitutes a pivotal challenge in the realization and scale-up of some functional nanomaterials. We have developed a light-driven large-area spinning-disk processor for this purpose,

Solar ablation creates the sharp radiative and temperature gradients, as well as the high-temperature annealing environment, that favor nanomaterial syntheses. Using highly concentrated sunlight, we generated fullerene-like MoS2, ranging from single-
