Computational Modeling of Novel Bulk Materials for the Intermediate-Band Solar Cells
Rasukkannu, Murugesan; Velauthapillai, Dhayalan; Vajeeston, Ponniah (Journal article, 2017)Research communities have been studying materials with intermediate bands (IBs) in the middle of the band gap to produce efficient solar cells. Cells based on these materials could reach theoretical efficiencies up to ... -
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 ... -
Hybrid Density Functional Study of Au2Cs2I6, Ag2GeBaS4, Ag2ZnSnS4, and AgCuPO4 for the Intermediate Band Solar Cells
Rasukkannu, Murugesan; Velauthapillai, Dhayalan; Vajeeston, Ponniah (Journal article; Peer reviewed, 2018)We present a comprehensive investigation of the structural, electronic, mechanical, and optical properties of four promising candidates, namely Au2Cs2I6, Ag2GeBaS4, Ag2ZnSnS4, and AgCuPO4, for application in photovoltaic ... -
In-depth first-principle study on novel MoS 2 polymorphs
Eidsvåg, Håkon; Rasukkannu, Murugesan; Velauthapillai, Dhayalan; Vajeeston, Ponniah (Peer reviewed; Journal article, 2021)Molybdenum disulphide (MoS2) is a rising star among transition-metal dichalcogenides in photovoltaics, diodes, electronic circuits, transistors and as a photocatalyst for hydrogen evolution. A wide range of MoS2 polymorphs ... -
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, ... -
TiO2 as a Photocatalyst for Water Splitting—An Experimental and Theoretical Review
Eidsvåg, Håkon; Bentouba, Said; Vajeeston, Ponniah; Shivatharsiny, Yohi; Velauthapillai, Dhayalan (Journal article; Peer reviewed, 2021)Hydrogen produced from water using photocatalysts driven by sunlight is a sustainable way to overcome the intermittency issues of solar power and provide a green alternative to fossil fuels. TiO2 has been used as a ...
