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...

Anti-reflective and superamphiphilic coatings on polycarbonate
Valentim, P. T.; Retolaza, A.; Llobet, J.; Araújo, C.; Cruz, Sílvia Manuela Ferreira; Machado, C.; Pontes, A. J.; Santos, H.; Sousa, P. C.In this work, we investigated the transmission enhancement of a polycarbonate substrate (PC) at the beginning of the near-infrared part of the electromagnetic spectrum, by incorporating anti-reflective coatings (ARC) on the surface. Thin film ARC formed by combining layers of SiO2, TiO2, and SiNx were studied, and the influence of the layers thickness on the optical response of the systems was explored, with th...
Implementation of a viscoelastic constitutive model using the object-oriented p...
Silva, Henrique Nogueira; Soares, Jorge Barbosa; Parente Junior, Evandro; Sousa, P. C.The numerical implementation of the time-dependent linear viscoelastic constitutive model using object-oriented programming is discussed here. This paper is divided in two main parts: (i) a brief discussion of the numerical integration of linear viscoelastic constitutive equations, including the use of Prony series for characterization of viscoelastic materials (e.g. asphalt pavement surfaces) and (ii) the clas...
