Transient Decay of the Excess Minority of Electrons Density Photogenerated within the Active Layer of Bulk-Heterojunction Organic Solar Cell.
Transient decay occurs between two steady states through operating points of a Bulk-Heterojunction
Organic Solar Cell (BHJ-OSC) based on blend of poly (3-hexylthiophene-2, 5-diyl) (P3HT) as electron-donor and a
soluble derivative of fullerene called [6, 6]-phenyl C61-butyric acid methyl ester (PCBM) as electron-acceptor under
various monochromatic wavelength ? of irradiation of the spectrum visible is investigated. Basically, since the
phenomenological parameters such as the organic photoactive layer thickness, the electron lifetime, the electron
diffusion length, and the electron mobility are deemed paramount important for the electron generation and collection
at the cathode electrode their dependence effects upon the transient decay of the excess minority of electrons are
reported. Likewise, both the influence of the electrons recombination at the interfaces of the electrodes and the
bimolecular recombination within the bulk of P3HT:PCBM is also especially paid attention.
