| Title: | Short circuit current improvement in planar heterojunction organic solar cells by multijunction charge transfer | Authors: | Wang, JC Shi, SQ Leung, CW Lau, SP Wong, KY Chan, PKL |
Issue Date: | 30-Jan-2012 | Source: | Applied physics letters, 30 Jan. 2012, v. 100, no. 5, 053301, p. 1-3 | Abstract: | A multijunction structure was applied on an organic photovoltaic (OPV) device for broadening the absorption spectrum and enhancing the power conversion efficiency through charge transfer process. By inserting the tris[4-(2-thienyl)]amine (TTPA) into a boron subphthalocyanine chloride (SubPc)/C₆₀ OPV device, the short circuit current density (J[sub sc]) showed a 47.5% increases from 3.05 to 4.50 mA/cm² in the bilayer planar heterojunction device, while the open circuit voltage (V[sub oc]) remained constant. Based on the single junction (TTPA/SubPc) device and photoluminescence absorption results, we confirmed both TTPA/SubPc and SubPc/C₆₀ junctions are contributing to the exciton dissociation process hence the efficiency enhancement. | Keywords: | Charge exchange Current density Dissociation Excitons Fullerenes Organic compounds Photoluminescence Power conversion Short-circuit currents Solar cells |
