Journal ArticleDOI
Plasmonic silver nanoparticles for improved organic solar cells
Nikolaos Kalfagiannis,Panagiotis Karagiannidis,Charalampos Pitsalidis,N.T. Panagiotopoulos,C. Gravalidis,S. Kassavetis,Panos Patsalas,Stergios Logothetidis +7 more
TL;DR: In this article, the performance of organic solar cells, based on the bulk heterojunction system of P3HT:PCBM when adequate silver nanoparticles (NPs) are incorporated in two distinct places among the device structure is compared.
Journal ArticleDOI
Surface kinetics and subplantation phenomena affecting the texture, morphology, stress, and growth evolution of titanium nitride films
TL;DR: In this paper, a thorough study of the microstructure, texture, intrinsic stress, surface and interface morphology of transition metal nitride (mainly TiN but also CrN) films grown on Si by reactive sputter deposition is presented, with emphasis to the mechanisms of adatom migration on the surface and subplantation of energetic species.
Journal ArticleDOI
Optical and structural properties of ZnO for transparent electronics
Stergios Logothetidis,Argiris Laskarakis,S. Kassavetis,S. Lousinian,C. Gravalidis,George Kiriakidis +5 more
TL;DR: In this article, the effect of the deposition parameters of ZnO thin films in terms of their optical, structural and nanomechanical properties by employing Spectroscopic Ellipsometry (SE) in the Vis-fUV spectral region, and X-Ray Diffraction techniques was analyzed.
Journal ArticleDOI
Fully gravure printed organic photovoltaic modules: A straightforward process with a high potential for large scale production
C. Kapnopoulos,Evangelos Mekeridis,Lazaros Tzounis,Christos A. Polyzoidis,Alexandros Zachariadis,Sofia Tsimikli,C. Gravalidis,Argiris Laskarakis,Nikolaos Vouroutzis,Stergios Logothetidis +9 more
TL;DR: In this article, the authors describe a novel approach for the fabrication of flexible organic photovoltaic (OPV) modules with an inverted architecture by a versatile and scalable gravure printing process, while all the printing steps were performed in ambient conditions and were optimized for each of the OPV layers.
Journal ArticleDOI
Optical and nanomechanical study of anti-scratch layers on polycarbonate lenses
TL;DR: In this paper, the optical and nanomechanical properties of a polycarbonate (PC) based optical lens and an anti-scratch (AS) coating as a protective overcoat were investigated.
