    • Automatic solar cell diagnosis and treatment 

      Rodriguez, Alvaro; Gonzalez, Carlos; Fernandez, Andres; Rodriguez, Francisco; Delgado, Tamara; Bellmann, Martin Pawel (Peer reviewed; Journal article, 2020)
      Solar cells represent one of the most important sources of clean energy in modern societies. Solar cell manufacturing is a delicate process that often introduces defects that reduce cell efficiency or compromise durability. ...

    • Comparative validation of global and climate-specific decomposition models at high latitudes 

      Manni, Mattia; Nocente, Alessandro; Skeie, Kristian; Bellmann, Martin Pawel; Lobaccaro, Gabriele (Peer reviewed; Journal article, 2024)
      Reliable modelling of the solar potential of urban surfaces (i.e. roofs, facades and ground) in the built environment can contribute to boost the exploitation of solar energy. Empirical and quasi-physical models are combined ...

    • Effect of crucible rotation on the temperature and oxygen distributions in Czochralski grown silicon for photovoltaic applications 

      Popescu, Alexandra; Bellmann, Martin Pawel; Vizman, Daniel (Peer reviewed; Journal article, 2021)
      Temperature and oxygen distributions were numerically studied for the Czochralski (Cz) growth of 8′′ diameter silicon single crystals for photovoltaic applications. Fluctuations in the dopant concentration (striation ...

    • Empirical analysis of bifacial photovoltaic modules in high-latitude regions: Performance insights from a field laboratory in Norway 

      Dimd, Berhane Darsene; Garcia, Alfredo Sanchez; Bellmann, Martin Pawel (Peer reviewed; Journal article, 2024)
      This paper presents a comprehensive empirical analysis of bifacial photovoltaic (bPV) module performance in high-latitude regions, based on data collected from an outdoor field laboratory in Trondheim, Norway. It explores ...

    • Multi‐Stage Validation of a Solar Irradiance Model Chain: An Application at High Latitudes 

      Manni, Mattia; Nocente, Alessandro; Bellmann, Martin Pawel; Lobaccaro, Gabriele (Peer reviewed; Journal article, 2023)
      Evaluating how the sources of uncertainty in solar modelling (e.g., input parameters, developed model chain) can influence the results’ accuracy is one of the main challenges when applied at high latitudes. In this study, ...

    • NTNU-SINTEF SolarNet: A solar irradiation monitoring network at high latitudes 

      Manni, Mattia; Nocente, Alessandro; Bellmann, Martin Pawel; Völler, Steve; Sabatino, Marisa Di; Lobaccaro, Gabriele (Peer reviewed; Journal article, 2023)
      This study presents a monitoring network for solar irradiation at high latitudes, called NTNU-SINTEF SolarNet. The network collects, with a time resolution ranging from seconds to hours, solar irradiance data, e.g. global ...

    • Silicon anodes for lithium-ion batteries produced from recovered kerf powders 

      Wagner, Nils Peter; Tron, Artur; Tolchard, Julian R; Noja, Gianluigi; Bellmann, Martin Pawel (Peer reviewed; Journal article, 2019)
      Silicon kerf waste from a photovoltaic silicon production process is assessed as an anode material for application as a lithium ion battery anode. In contrast to previous studies, the Si-kerf is used as-produced, with no ...

    • Silicon kerf loss as a potential anode material for lithium-ion batteries 

      Søiland, Anne Karin; de Meatza, Iratxe; Muguruza, Ane; Xu, Yijiang; Bellmann, Martin Pawel (Peer reviewed; Journal article, 2024)
      In this work, industrially processed silicon kerf loss (abbreviated to silicon kerf) from the photovoltaic industry is assessed as an anode material for the lithium-ion battery (LIB). The study includes both a characterization ...

    • Validation of decomposition models for solar irradiance at high latitudes: A preliminary study 

      Manni, Mattia; Nocente, Alessandro; Skeie, Kristian; Bellmann, Martin Pawel; Lobaccaro, Gabriele (Peer reviewed; Journal article, 2023)
      The accurate estimation of buildings' solar potential contributes to boost the exploitation of solar energy at high latitudes. The decomposition of global irradiation into the direct and diffuse fractions is a fundamental ...
