Solar module orientation and tracking type performance and optimization J. Photonics Energy (IF 1.7) Pub Date : 2021-10-01 Sooraj P. Sharma, Paul W. Leu
The efficiency and performance of solar cells and modules are typically evaluated and reported at normal incidence under peak solar radiation. We present a simple clear-sky model for solar irradiance that can be used to study the angular and annual performance of new photovoltaic materials. Using this model, we study the effect of solar module orientation for fixed-tilt module installations and different

Dynamic control of polarized thermal emission from VO2 nanofins J. Photonics Energy (IF 1.7) Pub Date : 2021-10-01 Caleb A. Estherby, Matthew D. Arnold, Matthew C. Tai, Angus R. Gentle
We demonstrate switchable polarized thermal emission from VO2 nanofin stacks fabricated by co-deposition, etching, and oxidation. We find that reverse switching of the thermal emission is enabled by a reflecting underlayer and induced by either short oxidation time or additional deposition of a reflecting underlayer. Observed thermal emission is well explained by a biaxial Bruggeman effective medium

Numerically enhancing daytime radiative cooling performance of random dielectric microsphere coatings by hollow structures J. Photonics Energy (IF 1.7) Pub Date : 2021-10-01 Meijie Chen, Shuang Li, Dan Pang, Yanwei Zhao, Yuan Yang, Hongjie Yan
Dielectric microsphere coatings for passive daytime radiative cooling (PDRC) are gaining attention owing to their low cost and potential for mass production. The cooling performance could be further enhanced to effectively reflect solar radiation and emit thermal radiation to the cold sky by designing microspheres suitable for PDRC applications. Hollow dielectric structures were numerically designed

Bilayer structured coating for radiative cooling applications J. Photonics Energy (IF 1.7) Pub Date : 2021-10-01 Rongbing Wan, Zhihao Ma, Weiping Xu, Wenbo Zhao, Jingtao Xu, Ronggui Yang
Daytime radiative cooling technology can cool objects to sub-ambient temperatures under direct sunlight without energy consumption. The technology relies on high reflectance of solar irradiation and high emissivity in the atmospheric window (infrared emission with 8 to 13 μm wavelengths). We report a bilayer structured coating for passive daytime sub-ambient radiative cooling. The bilayer radiative
