    • CoS2/TiO2 Nanocomposites for Hydrogen Production under UV Irradiation 

      Shanmugaratnam, Sivagowri; Velauthapillai, Dhayalan; Ravirajan, Punniamoorthy; Christy, Alfred Antony; Shivatharsiny, Yohi (Journal article; Peer reviewed, 2019)
      Transition metal chalcogenides have intensively focused on photocatalytic hydrogen production for a decade due to their stronger edge and the quantum confinement effect. This work mainly focuses on synthesis and hydrogen ...

    • First-Principle Calculation of High Absorption-TlGaTe2 for Photovoltaic Application 

      Rasukkannu, Murugesan; Velauthapillai, Dhayalan; Vajeeston, Ponniah (Journal article; Peer reviewed, 2019)
      We use first-principle calculations based on hybrid functional and the Bethe-Salpeter equation method to investigate the electronic and optical properties of dichalcogenide TlGaTe2. Based on theoretical studies, TlGaTe2 ...

    • Industrial Thermal Insulation Properties above Sintering Temperatures 

      Gunnarshaug, Amalie; Log, Maria-Monika Metallinou; Log, Torgrim (Peer reviewed; Journal article, 2021)
      Processing highly flammable products, the oil and gas (O&G) industry can experience major explosions and fires, which may expose pressurized equipment to high thermal loads. In 2020, oil fires occurred at two Norwegian O&G ...

    • Powder pressed cuprous iodide (CuI) as a hole transporting material for perovskite solar cells 

      Uthayaraj, Siva; Karunarathne, DGBC; Kumara, GRA; Murugathas, Thanihaichelvan; Rasalingam, Shivatharsiny; Rajapakse, R.M.G.; Ravirajan, Punniyamoorthy; Velauthapillai, Dhayalan (Peer reviewed; Journal article, 2019)
      This study focuses on employing cuprous iodide (CuI) as a hole-transporting material (HTM) in fabricating highly efficient perovskite solar cells (PSCs). The PSCs were made in air with either CuI or 2,2′,7,7′-Tetrakis[N, ...

    • Properties of novel non-silicon materials for photovoltaic applications: A first-principle insight 

      Rasukkannu, Murugesan; Velauthapillai, Dhayalan; Bianchini, Federico; Vajeeston, Ponniah (Journal article; Peer reviewed, 2018)
      Due to the low absorption coefficients of crystalline silicon-based solar cells, researchers have focused on non-silicon semiconductors with direct band gaps for the development of novel photovoltaic devices. In this study, ...

    • Study of Industrial Grade Thermal Insulation at Elevated Temperatures 

      Gunnarshaug, Amalie; Log, Maria-Monika Metallinou; Log, Torgrim (Peer reviewed; Journal article, 2020)
      Thermal insulation is used for preventing heat losses or heat gains in various applications. In industries that process combustible products, inorganic-materials-based thermal insulation may, if proven sufficiently heat ...
