Potential of Photovoltaic and Diesel Off‐Grid Systems for Irrigation in Brazil Considering Carbon Credits

Irrigation and Drainage, Volume 74, Issue 4, Page 1553-1574, October 2025.
ABSTRACT Irrigation is a crucial practice for the security of rural businesses, ensuring agricultural production even in periods without rainfall. This work aimed to analyse the financial viability of an off‐grid photovoltaic (PV) system as an alternative to traditional energy sources for pumping irrigation in Brazilian agricultural areas.

3E and Climatic Analysis of Hybrid Solar System Integrated With a Ground Source Heat Pump for Multi‐Micro‐Generation Energy Supply

Energy Science &Engineering, Volume 13, Issue 6, Page 3013-3030, June 2025.
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

Progress in Photovoltaics: Research and Applications, Volume 33, Issue 4, Page 551-559, April 2025.
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 ...

Approche Expérimentale des Courbes de Sorption de la Menthe en vue d’un Séchage par Energie Solaire

Journal of Renewable Energies, 1999
Les teneurs en eau d’équilibre d’un produit à sécher sont indispensables lors d’une opération de stockage et de séchage solaire par convection forcée. Ces valeurs sont souvent relevées à partir des courbes dites isothermes de sorption. Ainsi, le présent travail se propose de déterminer expérimentalement les isothermes de sorption de la menthe (mentha ...

Switchable Narrowband Diffuse Thermal Emission With an In3SbTe2‐Based Planar Structure

Laser &Photonics Reviews, Volume 19, Issue 5, March 4, 2025.
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 ...
