Hollow core circular tube lattice fibers (HC-CTLFs) have been recently proposed and experimentally demonstrated to match many of these conditions. They are composed of a hollow core surrounded by a circular arrangement of dielectric tubes. CTLFs guide via Inhibited Coupling (IC) which doesn't rely on photonic bandgap and the confinement depends on a strong reduction of the coupling between core modes and cladding modes. The losses in CTLF can be divided into the confinement loss and the absorption loss. Both of them can be reduced by enlarging the fiber core size, but this makes the fiber big and hardly flexible. For an optimized design of the fiber, scaling law analysis plays an important role in determining the best trade-off between low loss and small size. Here the dependence of the confinement and absorption loss on frequency and core radius are numerically investigated. Results show that confinement loss exhibits a stronger dependence of core size and frequency with respect to other hollow core fibers proposed for THz waveguiding such as Kagome, Bragg, and Tube fibers as well as to dielectric absorption loss.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117009424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we made a comparative study between the standard and the inverted polymer solar cells based on the bulk-heterojunction structure. We realized standard and inverted polymer solar cells using a blend film of poly[(4,8-bis-(2-ethylhexyloxy)-benzo[1,2-b;4,5-b']dithiophene)-2,6-diyl-alt-(4-(2-ethylhexanoyl)-thieno[3,4-b]thiopene)-2,6-diyl] / [6,6]-phenyl C71 butyric acid methyl ester (PBDTTT-C:[70]PCBM) blend films. In the standard architecture, the transparent indium tin oxide (ITO) electrode is coated with poly-(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) and used as a hole collecting electrode, while in an inverted device configuration, the ITO electrode is turned into the electron collecting contact by surface modification with zinc oxide (ZnO). The standard cells sequence is ITO/PEDOT:PSS/PBDTTT-C:[70]PCBM/Ca/Al and the inverted cells one is ITO/ZnO/PBDTTT-C:[70]PCBM/MoO3/Ag. We studied the electrical behavior (by means of IV-dark and IV-light at different illumination levels and external quantum efficiency measurements) of both kinds of devices in order to investigate the influence of the architecture (standard vs inverted) on the performance of the solar cells.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126981365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural, optical and photoconductivity properties of the films have been investigated. The increase in rf power in the 40-80 W range enhances the incorporation of carbon in the amorphous matrix and decreases the fraction and size of the silicon crystallites leading to an enlargement of the optical band gap from 2.07 to 2.20 eV. Steady state spectral photoconductivity measurements have been performed under monochromatic radiations in the 460-1050 nm range. It has been demonstrated that monomolecular recombination kinetics occurs in the samples under illumination and the deterioration of the phototransport properties, with increasing the rf power, are correlated to the reduction of the mobility lifetime product of the free electrons. However, the mobility lifetime product as a function of the optical band gap shows high values as in the case of device quality films deposited by silane-methane mixtures diluted in hydrogen.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123189105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
