Dye-sensitized solar cell with a pairof carbon-based electrodes
Kyaw, A. K. K.; Tantang, H.; Wu, T.; Ke, L.; Wei, J.; Demir, Hilmi Volkan; Zhang, Q.; Sun, X. W. (IOP Publishing, 2012-04-02)We have fabricated a dye-sensitized solar cell (DSSC) with a pair of carbon-based electrodes using a transparent, conductive carbon nanotubes (CNTs) film modified with ultra-thin titanium-sub-oxide (TiOx) as the working ... -
Dye-sensitized solar cell with a titanium-oxide-modified carbon nanotube transparent electrode
Kyaw, A. K. K.; Tantang, H.; Wu, T.; Ke, L.; Peh, C.; Huang, Z. H.; Zeng, X. T.; Demir, Hilmi Volkan; Zhang, Q.; Sun, X. W. (American Institute of Physics, 2011-07-15)Transparent and conductive carbon-based materials are promising for window electrodes in solid-state optoelectronic devices. However, the catalytic activity to redox reaction limits their application as a working electrode ... -
Effect of shell thickness on small-molecule solar cells enhanced by dual plasmonic gold-silica nanorods
Xu, X.; Du, Q.; Peng, B.; Xiong, Q.; Hong, L.; Demir, Hilmi Volkan; Wong, T. K. S.; Kyaw, A. K. K.; Sun, X. W. (AIP Publishing, 2014-09-19)Chemically synthesized gold (Au)-silica nanorods with shell thickness of 0 nm-10 nm were incorporated into the bulk heterojunction of a small-molecule organic solar cell. At optimal (1 wt. %) concentration, Au-silica ... -
Enhanced efficiency of solution-processed small-molecule solar cells upon incorporation of gold nanospheres and nanorods into organic layers
Xu, X.; Kyaw, A. K. K.; Peng, B.; Du, Q.; Hong, L.; Demir, Hilmi Volkan; Wong, T. K. S.; Xiong, Q.; Sun, X. W. (Royal Society of Chemistry, 2014)The significantly enhanced performance upon incorporation of Au nanoparticles in solution-processed small-molecule solar cells is demonstrated. Simultaneously incorporating Au nanospheres into the hole transport layer and ... -
Free-standing ZnO-CuO composite nanowire array films and their gas sensing properties
Wang, J. X.; Sun, X. W.; Yang, Y.; Kyaw, A. K. K.; Huang, X. Y.; Yin, J. Z.; Wei, J.; Demir, Hilmi Volkan (IOP Publishing, 2011-07-19)A modified hydrothermal method was developed to synthesize ZnO-CuO composite nanostructures. A free-standing film made of ZnO-CuO nanostructures was assembled on the surface of the hydrothermal solution with a smooth surface ... -
Influence of gold-silica nanoparticles on the performance of small-molecule bulk heterojunction solar cells
Xu, X.; Kyaw, A. K. K.; Peng, B.; Xiong, Q.; Demir, Hilmi Volkan; Wang Y.; Wong, T. K. S.; Sun, X. W. (Elsevier BV * North-Holland, 2015)Light trapping by gold (Au)-silica nanospheres and nanorods embedded in the active layer of small-molecule (SM) organic solar cell has been systematically compared. Nanorod significantly outperforms nanosphere because of ... -
Microstructured porous ZnO thin film for increased light scattering and improved efficiency in inverted organic photovoltaics
Nirmal, A.; Kyaw, A. K. K.; Sun, X. W.; Demir, Hilmi Volkan (Optical Society of America, 2014)Microstructured porous zinc oxide (ZnO) thin film was developed and demonstrated as an electron selective layer for enhancing light scattering and efficiency in inverted organic photovoltaics. High degree of porosity was ... -
