Improved Power Conversion Efficiency of P3HT:PCBM Organic Solar Cells by Strong Spin-Orbit Coupling-Induced Delayed Fluorescence
Abstract
10 pags., 8 figs. ; Solution-processed organic bulk heterojunction solar cells based on poly(3-hexylthiophene) (P3HT) blended with [6,6]-phenyl-C60-butyric acid methyl ester are doped with different concentrations of iron (II,III) oxide nanoparticles (Fe3O4). The power conversion efficiency of the devices doped at low concentrations is improved up to 11%. The improvement finds its origin in a lower recombination current, which is a consequence of an increased effective exciton lifetime according to the J-V characteristics and the optoelectronical analysis of the films. The increase in performance cannot be attributed to changes in morphology or crystallinity according to grazing-incidence X-ray scattering experiments. The evolution of the solar cell short-circuit current at low doping concentrations is related to variations in the arrangement of the crystalline regions of P3HT. For high doping concentrations (above 1.0 wt%) the performance of the solar cell decays rapidly, ascribed to the increased leakage currents in the device caused by the presence of nanoparticles. Organic solar cells are doped with iron oxide nanoparticles. An increased efficiency for low doping concentrations is found and ascribed to a reduced device recombination, which is traced with prompt and delayed fluorescence measurements. Morphological and crystalline characterization is addressed by grazing-incidence small/wide-angle X-ray scattering in order to ensure that the improvement is not morphology related. ; Financial support by TUM.solar in the frame of the Bavarian Collaborative Research Project “Solar technologies go Hybrid” (SolTec), by the GreenTech Initiative (Interface Science for Photovoltaics – ISPV) of the EuroTech Universities and by the Nanosystems Initiative Munich (NIM) is acknowledged.
