  2. 11. Probing the effects of photodegradation of acceptor materials in polymer solar cells: bulk, surface, and molecular level

    Author : Vanja Blazinic; Ellen Moons; Leif Ericsson; Thomas Wågberg; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photovoltaics; polymer solar cell; conjugated polymers; fullerene; photo-oxidation; spectroscopy; Physics; Fysik;

    Abstract : Polymer solar cells (PSC) have reached record power conversion efficiencies of over 15%. The operational lifetime of PSCs, however, has to increase for their use in large area outdoor applications. READ MORE

  4. 12. Cost-effective Communication and Control Architectures for Active Low Voltage Grids

    Author : Mikel Armendáriz; Lars Nordström; Sami Repo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active low voltage distribution grids; CAPEX OPEX; communication control architectures; cost-effectiveness; MPC; multiagent systems; photovoltaics; voltage control.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The monitoring and control of low voltage distribution grids has historically been disregarded due to the unidirectional flow of power. However, nowadays the massive integration of distributed energy resources into distribution grids, such as solar photovoltaics, distributed storage, electric vehicles and demand response programs, presents some challenges.

  5. 13. Uncertainty modeling for load flow and hosting capacity analysis of urban electricity distribution systems

    Author : Umar Hanif Ramadhani; Joakim Widén; Joakim Munkhammar; Bri-Mathias Hodge; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty model; Photovoltaics; Electric vehicle; Residential buildings; Hosting capacity; Probabilistic load flow; Electricity distribution systems; Urban Energy Systems; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : Urban demographics are changing, with more than half of the global population currently residing in urban areas. Traditionally, cities are often seen as passive energy consumers relying on external centralized systems. Motivated by the need to mitigate climate change, a shift is underway as cities actively shape energy systems. READ MORE
