New Strategies and Simulation Tools to Optically Design a Field of Heliostats
A heliostats field is an array of mirrors concentrating the solar power on a receiver, typically placed on a tower. Our research experience in the optical design of heliostats fields for Concentrating Solar Power plants suggested using apposite simulation procedures, which were especially developed to simplify the reproduction of heliostats fields and ...

ABSTRACT Renewable energy sources are extensively studied due to their clean and sustainable nature. Human energy needs can be classified into four categories: heating, cooling, electricity, and transportation. Heating and electricity have garnered more research attention because of their larger share and the variety of technologies used.

Tips and Tricks for a Good Encapsulation for Perovskite‐Based Solar Cells
Encapsulation materials for perovskite solar cells were explored, focusing on their ability to block moisture, endure high temperatures, and maintain mechanical stability. Ionomer encapsulant combined with a butyl edge seal provides strong moisture resistance but leads to delamination during thermal cycling, whereas polyolefin with butyl offers a ...

Switchable Narrowband Diffuse Thermal Emission With an In3SbTe2‐Based Planar Structure
The study presents a planar reconfigurable thermal emitter based on phase‐change material In3SbTe2, achieving high narrowband emissivity in the amorphous phase and low broadband emissivity in the crystalline phase. The design results in angle‐ and polarization‐independent emission, allowing for centimeter‐scale programmable patterns with a resolution ...
