Pyroelectric thermal–electrical cycles enable a class of solid-state heat engines that convert waste heat to electrical energy. This article numerically investigates thermal-to-electrical energy conversion in a PbZr0.52Ti0.48O3 (PZT) pyroelectric l

Solid-state refrigeration represents a promising alternative to vapor compression refrigeration systems which are inefficient, unreliable, and have a high global warming potential. However, several solid-state cooling technologies—including those r

Passive daytime radiative cooling presents a promising low-cost refrigeration solution but has thus far relied on specialized nanophotonic structures. Here Bhatia et al. show a directional approach that decouples solar reflectance and infrared emissi

Silica aerogel has been known as a promising candidate for high performance transparent insulation material (TIM). Optical transparency is a crucial metric for silica aerogels in many solar related applications. Both scattering and absorption can red

Air conditioning and refrigeration account for about a quarter of our total energy demand (US Energy Information Administration, 2021). These cooling needs are primarily met by vapor compression systems which are inefficient, unreliable and have a hi

Summary Saturated steam (>121°C and >205 kPa) is widely used in the medical sterilization process known as autoclaving. However, solar-driven steam generation at such high temperature and pressure requires expensive optical concentrators. We demonst

Optically selective and thermally insulating (OSTI) covers, such as polyethylene aerogels (PEAs), have recently been proposed to improve subambient daytime radiative cooling performance by minimizing parasitic solar absorption and heat gain at the em
