Perovskite solar cells may irrupt into the energy market in the near future. However, for this to happen, some challenges still need to be overcome. One of them is the production of these devices on an industrial scale. In fact, so far, there is no processes that meet all the necessary conditions for the industrial manufacture of these solar cells to become viable. Now, a development carried out by CINE…
Speed champions in the storage and delivery of electrical energy, supercapacitors can play a very important role in a society that is less and less dependent on fossil fuels and more and more reliant on the use of electricity. In order for supercapacitors to perform well and be able to store the greatest possible amount of energy, the choice of the electrode material is essential. Among the favorites are composites…
A team from CINE used computational tools to screen two-dimensional materials from the dichalcogenated transition metals (TMDs) family, identifying the best candidates for use in high-performance solar cells. Among 72 materials initially evaluated, only three met all the conditions for this application. Completely carried out through computer simulations, the study made feasible a work that would require much greater resources and time if done experimentally through synthesis and characterization of…
O professor Rubens Maciel Filho (UNICAMP), pesquisador principal do Programa de Armazenamento Avançado de Energia do CINE, proferiu palestra na International Energy Agency (IEA) sobre matriz energética e mobilidade em países de economia emergente, que incluem o Brasil. A palestra online foi realizada no dia 20 de abril dentro de um evento que é realizado duas vezes por ano por um dos grupos de trabalho da IEA, liderado pelo Canadá e os…
The technology of lithium-oxygen batteries (Li-O2) may bring a significant increase in energetic density (quantity of energy stored by weight of battery) comparing to the devices that, today, are in the market, such as ion and lithium batteries. However, several limitations of this technology still need to be overcome to make their commercial use viable. For this, it is necessary to better understand the reactions that occur during the charge…
O professor Ernesto Chaves Pereira, pesquisador do CINE, é coordenador da unidade da Empresa Brasileira de Pesquisa e Inovação Industrial (EMBRAPII) na Universidade Federal de São Carlos (UFSCar), dedicada ao desenvolvimento de materiais avançados, funcionais e para processos sustentáveis. A EMBRAPII tem o propósito de apoiar a inovação tecnológica em empresas pela interação destas com instituições de pesquisa. Além disso, a EMBRAPII cofinancia o desenvolvimento destes projetos de inovação em até…
No Dia Internacional das Mulheres e Meninas na Ciência, 11 de fevereiro, começou o “II Fronteiras em Eletroquímica e Eletroanalítica: avanços realizados por jovens mulheres cientistas”. Esse evento online e gratuito teve como objetivo reunir pesquisadoras que atuam no Brasil e no exterior para debater avanços na área de Eletroquímica/ Eletroanalítica e discutir o papel da mulher na Ciência e seus principais desafios. No evento, a pós-doc Juliane Fiates (IQSC-USP),…
The integration of solar cells to façades, windows, clothing and accessories has started to become reality thanks to the so-called emerging photovoltaic technologies, which are characterized for offering flexible and transparent devices. These devices, which cover organic, dye-sensitized and perovskites solar cells, have generated much interest, not only from companies and consumers, but also from researchers who are working to overcome the limitations of those technologies. For these research groups,…
