Paradigmas da energia solar no Brasil e no mundo [PDF]
Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental, 2016 With the gradual increase of population and consumption patterns of today's society, debates involving energy issues are becoming more frequent. The energetic basis of Brazil revolves around the dams, since the country has a great water conditions. With the scarcity of non-renewable resources caused by rampant consumption, they turn their eyes to the ...

Polymers for Advanced Technologies, Volume 36, Issue 5, May 2025.ABSTRACT In photovoltaic polymer synthesis research, it is routine to adapt chemical reactions while respecting the stoichiometric proportions of the reagents. Generally, researchers reduce the amounts of chemical reagents to save materials or adjust the necessary quantity according to the need to avoid waste, as these materials undergo chemical ...

Strain-balanced type-II superlattices for efficient multi-junction solar cells [PDF]
arXiv, 2016 We propose type-II GaAsSb/GaAsN superlattices (SLs) lattice-matched to GaAs as a novel material for the 1 eV sub-cells present in highly efficient GaAs/Ge-based multi-junction solar cells. We demonstrate that, among other benefits, the spatial separation of Sb and N allows a better control over composition and lattice matching, avoiding the growth ...

Extended Scenarios for Solar Radio Emissions With Downshifted Electron Beam Plasma Excitations
Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.Abstract First‐principle studies of radiative processes aimed at explaining the origin of type II and type III solar radio bursts raise questions on the implications of downshifted electron beam plasma excitations with frequency (slightly) below the plasma frequency ω≲ωpe $\left(\omega \lesssim {\omega }_{pe}\right)$ in the generation of radio ...

Monolithic Interconnection of Thin‐Film Perovskite Photovoltaic Modules Using Aerosol Jet Printing
Energy Technology, Volume 13, Issue 4, April 2025.An innovative approach demonstrates the interconnection of semi‐transparent monolithic perovskite modules using the combination of laser scribing and aerosol jet printing (AJP). Five interconnected cells are produced. Perovskite photovoltaic modules with AJP interconnects showed comparable performance to those fabricated using evaporated ...

A Systems Thinking Approach to Nuclear Pedagogy and Workforce Development
Journal of Critical Infrastructure Policy, Volume 6, Issue 2, Fall/Winter 2025.ABSTRACT Nuclear technology's controversial status has been shaped by its early use in military applications, fear driven by high‐profile accidents, and unresolved waste management challenges. There have, on the other hand, been periodic claims that a “nuclear renaissance” is imminent, driven by different dynamics at different times, most recently ...
