Bulk Heterojunction Solar Cell with Nitrogen-Doped Carbon Nanotubes in the Active Layer: Effect of Nanocomposite Synthesis Technique on Photovoltaic Properties
Keru, Godfrey K.; Ndungu, P. G.; Mola, G. T.; Nyamori, V. O. (2015-05-08)Nanocomposites of poly(3-hexylthiophene) (P3HT) and nitrogen-doped carbon nanotubes (N-CNTs) have been synthesized by two methods; specifically, direct solution mixing and in situ polymerization. The nanocomposites were ... -
Charge extracting buffer layers in bulkheterojunction organic solar cell
Keru, Godfrey K.; Ndungu, P. G.; Nyamori, V. O.; Mola, G. T. (Springer, 2015-08-27)The effects of boron and nitrogen-doped carbon nanotubes (B- or N-CNTs) have been investigated as photoactive and charge extracting layer in bulk heterojunction organic solar cell composed of poly(3-hexylthiophene) [P3HT] ... -
Effect of boron concentration on physicochemical properties of boron-doped carbon nanotubes
Keru, Godfrey K.; Ndungu, P. G.; Nyamori, V. O. (Elsevier, 2015-01-07)Boron-doped carbon nanotubes (B-CNTs) were synthesized using chemical vapour deposition (CVD) floating catalyst method. Toluene was used as the carbon source, triphenylborane as boron as well as the carbon source while ... -
Nitrogen-Doped Carbon Nanotubes Synthesised by Pyrolysis of (4-{[(Pyridine-4-yl)methylidene]amino}phenyl)ferrocene
Keru, Godfrey K.; Ndungu, P. G.; Nyamori, V. O. (Hindawi Publishing Corporation, 2013-08-13)Nitrogen-doped carbon nanotubes (N-CNTs) were synthesized by pyrolysis of (4-{[(pyridine-4-yl)methylidene]amino}phenyl) ferrocene in a solution of either acetonitrile or toluene as carbon source. This was achieved by testing ... -
Organic Solar Cells with Boron- or Nitrogen-Doped Carbon Nanotubes in the P3HT : PCBM Photoactive Layer
Keru, Godfrey K.; Ndungu, P. G.; Mola, G. T.; Nogueira, A. F.; Nyamori, V. O. (Hindawi Publishing Corporation, 2015-12-02)Either boron- or nitrogen-doped carbon nanotubes (B- or N-CNTs) were incorporated in bulk heterojunction organic solar cells photoactive layer composed of poly(3 hexylthiophene) (P3HT) : (6,6)-phenyl-C61-butyric acid methyl ... -
A review on carbon nanotube/polymer composites for organic solar cells
Keru, Godfrey K.; Ndungu, P. G.; Nyamori, V. O. (John Wiley & Sons, Ltd., 2014-04-13)Carbon nanotubes (CNTs) have unique properties, such as their electrical conductivity, that enable them to be combined with conducting polymers to form composites for use in organic solar cells (OSCs). It is envisaged that ...
