Analysis of Excitons Distribution of Bilayer-Heterojunction Organic Solar Cell Based on CuPc and C60: Excitons Total Dissociation at the p-n Junction.
Theoretical insight of the dependence effect of the total excitons dissociation at the p_n junction of a bilayer-Heterojunction Organic Solar Cell (bHJ-OSC) based on copper phthalocyanine (CuPc) as electron-donor and fullerene (C60) as electron-acceptor is reported. In order to determine new expression of the optical generation rate and density of excitons photogenerated in the organic photoactive layer of CuPc/C60 of the bHJ-OSC the T-Matrix theory is applied with the Abeles mathematical formalism. The excitons density of distribution is investigated introducing new excitons dissociation parameters at the different interfaces of the organic photoactive region, i.e. the exciton dissociation velocities Sdp, Sdg, Sdj and Sdn respectively associated to the transparent anode (ITO: Indium thin oxide)/donor (CuPc), the donor (CuPc)/acceptor (C60) and the acceptor (C60)/metallic cathode (Al: aluminium) interfaces. Moreover, the competitive role of the monochromatic wavelength ? of the incoming light and the thickness w of the organic photoactive layer (CuPc/C60) on the exciton density is emphasized.
