DHICA ion-modified melanin based porous Si solar cell
M. Semenenko, T. Yu. Obukhova, S. O. Kravchenko +8
This work studies photosensitivity and current-voltage characteristics under illumination of water-soluble eumelanin films based on DHICA tetramers and hybrid eumelanin/porous Si p…
Identification of formation of amorphous Si phase in SiOxNy films produced by plasma enhanced chemical vapor deposition
M. V. Voitovych, A. Sarikov, V. O. Yukhymchuk +2
Peculiarities of formation of inclusions of amorphous Si (a-Si) phase in Si-rich Si oxynitride films grown by plasma-enhanced chemical vapor deposition (PECVD) are studied by combi…
Dispersed multi-walled carbon nanotubes in polyvinyl butyral matrix for transparent ionic conductive films
Mykola O. Semenenko, Sergii O. Kravchenko, Nadiia V. Siharova +7
In this work, we develop methods for increasing the dispersion degree of agglomerated multiwalled carbon nanotubes with subsequent introduction of them into polyvinyl butyral to cr…
Optical studies of melanin films as a material for solar light absorbers
T. Obukhova, M. Semenenko, M. Dusheiko +10
This study investigates optical and electrical properties of thin melanin films self-organized grown from water solutions of eumelanin extracted from edible plants. The melanin fil…
