Cu(In,Ga)Se2 based ultrathin solar cells the pathway from lab rigid to large sc...
Lopes, T. S.; Teixeira, J. P.; Curado, M. A.; Ferreira, B. R.; Oliveira, A. J. N.; Cunha, J. M. V.; Monteiro, M.; Violas, A.; Barbosa, J. R. S.The incorporation of interface passivation structures in ultrathin Cu(In,Ga)Se2 based solar cells is shown. The fabrication used an industry scalable lithography technique—nanoimprint lithography (NIL)—for a 15 × 15 cm2 dielectric layer patterning. Devices with a NIL nanopatterned dielectric layer are benchmarked against electron-beam lithography (EBL) patterning, using rigid substrates. The NIL patterned devic...

Effects of quercetin in transcriptional regulation of fetal hemoglobin
Canteiro, B.; Mendes, M.; Delgadinho, Mariana; Oliveira, K.; Ginete, Catarina; Gomes, M.; Brito, Miguel; Gomes, Anita Q.; Ribeiro, EdnaPurpose: Sickle cell disease (SCD) is a genetic blood disorder that affects the shape and transport of red blood cells (RBCs) in blood vessels, leading to various clinical complications. The pharmacological reactivation of Fetal Hemoglobin (HbF) is considered to be a viable therapeutic method in SCD. In this regard, hydroxyurea (HU), a powerful ribonucleotide reductase inhibitor, is being employed as a HbF-indu...
Design of experiments optimization of fluorine-doped tin oxide films prepared b...
Pinheiro, X.L.; Vilanova, A.; Mesquita, D.; Monteiro, M.; Eriksson, J.A.M.; Barbosa, J.R.S.; Matos, C.; Oliveira, A.J.N.; Oliveira, K.; Capitão, J.Transparent conducting oxides (TCOs) have witnessed an ever-expanding use in our lives through many optoelectronic applications, namely photovoltaic (PV) devices. Indium-tin oxide (ITO) is the most used and studied TCO, but it lacks thermal and chemical stability and indium is a scarce and toxic element. Fluorine-doped tin oxide (FTO) emerged as the most promising alternative to ITO, presenting better thermal a...
Perovskite Metal-Oxide-Semiconductor Structures for Interface Characterization
Cunha, J.M.V.; Barreiros, M. Alexandra; Curado, M.A.; Lopes, T.S.; Oliveira, K.; Oliveira, A.J.N.; Barbosa, J.R.S.; Vilanova, AntónioABSTRACT: Perovskite solar cells (PSCs) are one of the most promising photovoltaic technologies. Amongst several challenges, developing and optimizing efficient electron transport layers that can be up-scaled still remains a massive task. Admittance measurements on metal-oxide-semiconductor (MOS) devices allow to better understand the optoelectronic properties of the interface between perovskite and the charge ...

Assessing air pollution in European cities to support a citizen centered approa...
Rodrigues, V.; Gama, C.; Ascenso, A.; Oliveira, K.; Coelho, S.; Monteiro, Alexandra; Hayes, E.; Lopes, M.European cities have made significant progress over the last decades towards clean air. Despite this progress, several cities are still facing acute air pollution episodes, with various urban areas frequently exceeding air quality levels allowed by the European legal standards and WHO guidelines. In this paper, six European cities/ regions (Bristol, UK; Amsterdam, NL; Sosnowiec, PL; Ljubljana, SI; Aveiro, PT; L...
