Study of Ruthenium Complex Sensitizer and Gold Nanoparticles Doped Flexible Organic Solar Cells

Abstract

This work presents a flexible organic solar cell with a structure for ITO/PEDOT:PSS/P3HT:PCBM + ruthenium complex sensitizer and Au nanoparticles on a flexible substrate. The process and thickness of the PEDOT:PSS hole transport layer and P3HT:PCBM active layer were optimized. A ruthenium complex sensitizer and Au nanoparticles were then introduced into the P3HT:PCBM active layer to improve the performance of solar cells. For the ITO/PEDOT:PSS/P3HT:PCBM + ruthenium complex sensitizer and Au nanoparticles structure on a flexible polyimide (PI) substrate under 0.1 and 1 sun conditions, the measured short-circuit current density (J sc ), open-circuit voltage (V oc ), fill factor (FF), and efficiency (η) are 3.89 and 9.67 mA/cm 2 , 0.45 and 0.45 V, 0.266 and 0.232, and 4.65 and 1.01%, respectively.

Photovoltaic Performance of BHJ Organic Solar Cells Based on Incorporation of Ru Dye into P3HT:PCBM Matrix

“…Besides, Ru dyes have been used in organic solar cells in order modify the interface between electron transport layer such as TiO2 and electron-donor polymer [12][13][14][15]. Di-tetrabutylammonium cisbis(isothiocyanato) bis(2,2'-bipyridyl-4,4'-dicarboxylato) ruthenium(II) (N-719) is the most popular Ru dye for DSSCs and OPVs.…”

“…Ru metal complexes as a sensitizer have been widely used in dye-sensitized solar cells (DSSCs) because of their favorable properties such as wide absorption range, suitable energy levels and high stability [9][10][11]. Besides, Ru dyes have been used in organic solar cells in order modify the interface between electron transport layer such as TiO2 and electron-donor polymer [12][13][14][15]. Di-tetrabutylammonium cisbis(isothiocyanato) bis(2,2'-bipyridyl-4,4'dicarboxylato) ruthenium(II) (N-719) is the most popular Ru dye for DSSCs and OPVs.…”
