relation between spatial distribution of plasmonic nanoparticles and photovoltaic parameters in organic bulk heterojunction solar cells

Abstract- despite interesting physical flexibility and low-cost fabrication process, oscs has low efficiency due to the low light absorption. due to the unique electro-optical properties of plasmonic nanoparticles (nps) such as high absorption and light concentration, the metallic nps opened a potential application for enhancement of characteristics parameters of oscs. implementing plasmonic nps in host layer of osc causes changing in electronic properties such as light absorption, conductivity, diffusion length. spatial distribution of plasmonic nps directly affect the absorption and charge carrier transportation through active layer. in this paper, we perform the simulation analysis for investigation of metallic nps spatial location in near anode, middle and near cathode, on characteristics parameters of oscs via the drift-diffusion model. our results show that spatial redistribution of nps can be boost both short circuit current and open circuit voltage and simultaneously, power conversion efficiency. the simulation results show that best efficiency achieves in spatial distribution of nps in middle of active region that are in good agreement with published reports.
