• Magnetic field effects in dye-sensitized and organic solar cells

  Publikacja

  • M. Klein

  - Rok 2018

  The charge recombination and exciton dissociation are generally recognized as the basic electronic processes limiting the efficiency of photovoltaic devices. The aim of this thesis is to understand the electronic processes limiting the operation of efficient solar cells with particular emphasis on the role of electronic states endowed with magnetic dipole moment. The research work is divided into two parts. The first part deals...

  W pracy zaobserwowano stromy wzrost natężenia elektroluminescencji w polach magnetycznych nie przekraczających 300mT. Efekt ten wywołany jest magnetyczno polową redukcją stopnia zmieszania singletowych i trypletowych par elektron dziura, wymuszonego przez nadsubtelne oddziaływanie spinów elektronowych z ich otoczeniem jądrowym.

  - Scientific Reports - Rok 2016

  The charge recombination and exciton dissociation are generally recognized as the basic electronic processes limiting the efficiency of photovoltaic devices. In this work, we propose a detailed mechanism of photocurrent generation in dye-sensitized solar cells (DSSCs) examined by magnetic field effect (MFE) technique. Here we demonstrate that the magnitude of the MFE on photocurrent in DSSCs can be controlled by the radius and...

• Multidipoles model of ship's magnetic field

  Publikacja

  • M. Wołoszyn
  • P. Zimny
  • K. Jakubiuk

  - INTERNATIONAL JOURNAL OF APPLIED ELECTROMAGNETICS AND MECHANICS - Rok 2012

  Ships made of ferromagnetic metals interfere with Earth's magnetic field in their surrounding. The disturbance of the magnetic field makes possible localization and even identification of the ship, which could determine a threat to the ship. The measurement of the magnetic field around the ship enables to determine its magnetic signature. The paper presents a multidipoles model of the ship magnetic field, which allows to determine...

  - Rok 2007

  The 3-axis fluxgate magnetometer requires conducting a precise calibration in the magnetic field whose value is determined and which is characterized by the high uniformity of the distribution of the field, especially along the axis of the sensors. The generation of the magnetostatic field characterized by the high uniformity, can be achieved by using the Helmholtz's coils. The requirements of the uniformity of distribution of...

  - Rok 2005

  Do wymuszenia przerzutu prądu z bezpiecznika krótkotopikowego o dużym prądzie znamionowym, lecz małej zdolności wyłączania do do innego - o małym prądzie znamionowym, lecz dużej zdolności wyłączania konieczne jest wytworzenie przez bezpiecznik krótkotopikowy wysokiego napięcia łukowego. Do tego celu bezpiecznik z topikiem o długości 1 mm wyposażono w rożki łukowe i płykową komorę dejonizacyjną oraz zastosowano zewnętrzne pole...

• Performance of lubricated sliding contact in magnetic field

  Publikacja

  • T. Stolarski
  • Y. Makida

  - TRIBOLOGY LETTERS - Rok 2012

  Results of experimental studies concerning theinfluence of permanent magnetic field on wear of lubricatedsliding contact operating at short stroke and highfrequency are presented. It was found that horizontalmagnetic is affecting performance of the contact. Thejagged delamination regions produced in the presence of amagnetic field can be regarded as easily undergoing oxidisationbecause oxygen is readily adsorbed there. Magneticfield...
