Journal ArticleDOI
TCO/metal/TCO structures for energy and flexible electronics
C. Guillén,J. Herrero +1 more
TL;DR: In this paper, a critical review summarizes current TCO/metal/TCO research results, first analyzed for materials and thickness selection as a function of the optical transmittance and electrical resistance parameters, and then analyzed according to other important properties such as mechanical reliability and thermal and humidity stability.
Journal ArticleDOI

TL;DR: In this paper, a review on the recent work concerning Cd-free buffer and window layers in chalcopyrite solar cells using various deposition techniques as well as their adaptation to chal copyrite-type absorbers such as Cu(In,Ga)Se-2, CuInS2, or Cu(in,Ga)(S,Se)(2).
Journal ArticleDOI
Optical, electrical and structural characteristics of Al:ZnO thin films with various thicknesses deposited by DC sputtering at room temperature and annealed in air or vacuum
C. Guillén,J. Herrero +1 more
TL;DR: In this paper, the optical, electrical, and structural properties of transparent and conductive al-doped ZnO (AZO) films have been analyzed as a function of the film thickness and the annealing parameters by spectrophotometry, Hall effect measurements, and X-ray diffraction.
Journal ArticleDOI
ITO/metal/ITO multilayer structures based on Ag and Cu metal films for high-performance transparent electrodes
C. Guillén,J. Herrero +1 more
TL;DR: In this paper, the optical and electrical properties of transparent conductive indium tin oxide (ITO)/metal/ITO multilayer electrodes have been analyzed by sputtering at room temperature.
Journal ArticleDOI
Comparison study of ITO thin films deposited by sputtering at room temperature onto polymer and glass substrates
C. Guillén,J. Herrero +1 more
TL;DR: In this paper, the structure, morphology and electro-optical characteristics of the ITO/glass and ITO polymer samples have been analyzed by X-ray diffraction, atomic force microscopy, four-point electrical measurements and spectrophotometry.
