A Quarterthiophene-Based Dye as an Efficient Interface Modifier for Hybrid Titanium Dioxide/Poly(3-hexylthiophene)(P3HT) Solar Cells
Pirashanthan, Arumugam; Murugathas, Thanihaichelvan; Robertson, Neil; Ravirajan, Punniyamoorthy; Velauthapillai, Dhayalan (Journal article; Peer reviewed, 2019)This work focused on studying the influence of dyes, including a thiophene derivative dye with a cyanoacrylic acid group ((E)-2-cyano-3-(3′,3′′,3′′′-trihexyl-[2,2′:5′,2′′:5′′,2′′′- quaterthiophene]-5-yl) acrylicacid)(4T), ... -
Enhanced performance of nanoporous titanium dioxide solar cells using cadmium sulfide and poly(3-hexylthiophene) co-sensitizers
Thanihaichelvan, Murugathas; Sri Kodikara, Minidu Manoranjana Punya; Ravirajan, Punniyamoorthy; Velauthapillai, Dhayalan (Journal article; Peer reviewed, 2017)This work reports the effect of co-sensitization of nanoporous titanium dioxide using Cadmium Sulfide (CdS) and poly(3-hexylthiophene) (P3HT) on the performance of hybrid solar cells. CdS nanolayer with different thicknesses ... -
Perovskite Solar Cells: A Porous Graphitic Carbon based Hole Transporter/Counter Electrode Material Extracted from an Invasive Plant Species Eichhornia Crassipes
Selvakumar, P; Easwaramoorthy, Nandakumar; Natarajan, Muthukumarasamy; Santhanam, Agilan; Asokan, Vijayashankar; Venkatraman, Madurai Ramakrishnan; Senthilarasu, Sundaram; Ravirajan, Punniyamoorthy; Velauthapillai, Dhayalan (Peer reviewed; Journal article, 2020)Perovskite solar cells (PSCs) composed of organic polymer-based hole-transporting materials (HTMs) are considered to be an important strategy in improving the device performance, to compete with conventional solar cells. ... -
Polymer/Fullerene Blend Solar Cells with Cadmium Sulfide Thin Film as an Alternative Hole-Blocking Layer
Thanihaichelvan, Murugathas; loheeswaran, Selvadurai; Balashankar, Kailasabathy; Velauthapillai, Dhayalan; Ravirajan, Punniyamoorthy (Journal article; Peer reviewed, 2019)In this work, chemical bath-deposited cadmium sulfide (CdS) thin films were employed as an alternative hole-blocking layer for inverted poly(3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) bulk ... -
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, ...
