ENERGIA RENOVÁVEL: ENERGIA SOLAR FOTOVOLTAICA RESIDENCIAL

RECIMA21 - Revista Científica Multidisciplinar - ISSN 2675-6218, 2022
Este trabalho tem o objetivo de realizar um estudo sobre a energia solar fotovoltaica, informando que é uma energia obtida através da conversão direta da luz em eletricidade por meio do efeito fotovoltaico. A célula fotovoltaica é um dispositivo fabricado com material semicondutor, é a unidade fundamental desse processo de conversão.

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.
