  • Electrochemical Synthesis of Novel Zn-Doped TiO2 Nanotube/ZnO Nanoflake Heterostructure with Enhanced DSSC Efficiency 
    K, Aijo John; Naduvath, Johns; Mallick, Sudhanshu; Pledger, Jacob W; Remillard, SK; DeYoung, PA; Thankamoniamma, Manju; Shripathi, T; Philip, Rachel Reena (Springer, 2016-07-02)
    The paper reports the fabrication of Zn-doped TiO2 nanotubes (Zn-TONT)/ZnO nanoflakes heterostructure for the first time, which shows improved performance as a photoanode in dye-sensitized solar cell (DSSC). The layered ...
  • Lead free, air stable perovskite derivative Cs2SnI6 as HTM in DSSCs employing TiO2 nanotubes as photoanode 
    Peedikakkandy, Lekha; Naduvath, Johns; Mallick, Sudhanshu; Bhargava, Parag (ELSEVIER, 2018-12)
    Cs2SnI6 is an air-stable and non-toxic perovskite variant photovoltaic material which exhibits p-type conductivity under doped conditions. In this work, we report the synthesis and stability studies of Cs2SnI6 towards its ...
  • Multipodal formation of Tio2 nanotubes using anodization 
    Naduvath, Johns; Bhargava, Parag; Mallick, Sudhanshu (American Institute of Physics Inc., 2019-03-22)
    The titanium dioxide nanotube arrays with large pore size and multipodal nature have many applications including solar cells applications, three terminal devices, drug delivery and other light harvesting applications. A ...
  • A simple method to fabricate metal doped TiO2 nanotubes 
    K, Aijo John; Naduvath, Johns; Remillard, Stephen K; Shaji, Sadasivan; DeYoung, Paul A; Kellner, Zachary T; Mallick, Sudhanshu; Thankamoniamma, Manju; Okram, Gunadhor S; Philip, Rachel Reena (ELSEVIER, 2019-07-01)
    A simple electrochemical method for effective doping of TiO2 nanotubes with metals is presented here. The doping is done in a two-stage cost effective process and is found to result in uniform doping concentration, without ...
