Similar Device Architectures for Inverted Organic Solar Cell and Laminated Solid-State Dye-Sensitized Solar Cells

Abstract

Here, we examine the device architecture of two different types of solar cells mainly inverted organic solar cells and solid state dye-sensitized solar cells (DSSCs) that use organic materials as hole transportation. The inverted organic solar cells structure is dominated by work on titanium dioxide (TiO 2 ) and zinc oxide (ZnO). These layers are sensitized with dye in solid state DSSCs. Because of the similar device architecture, it becomes possible to fabricate laminated solid-state DSSCs. The performance of the device was improved by varying the top metal electrode. In laminated solid-state DSSC, we expect that excited dye molecules inject electron into the conduction band of nanocrystalline TiO 2 layer, whereas P3HT provides efficient hole transportation. These solar cells are promising for future energy source as they are cheaper, light weight, flexible and made into large areas, which are showing growing importance.

Self-assembled silver nanowires as top electrode for poly(3,4-ethylenedioxythiophene):poly(stylenesulfonate)/n-silicon solar cell

“…AgNWs were prepared by polyol method [20][21][22] [20][21][22]. Figure 1 (a) shows the SEM image of as-synthesized…”

“…and transparency, because silver has the lowest resistivity (as low as 1.59 x 10 -6 Ω.cm) among metals [20][21][22][23][24][25][26][27]. Silver is stable in pure air and water and, therefore, has high corrosion resistance.…”

Tin instead of aluminum as a back electrode in P3HT:PC71BM organic solar cells

“…Similarly, the back electrode such as silver, gold or aluminum requires excellent electrical conductivity and a suitable work function, depending on the configuration of the solar cell. Silver [6][7][8] and gold 9) nanoparticles are suitable as counter electrodes in dye-sensitized solar cells due to their high electrical conductivity, transparency, high corrosion resistance, stability in pure air and water and good catalytic properties. 10) In perovskite solar cells, silver 11) and gold 12) have been reported to be appropriate as back electrodes in several works and different perovskite solar cell architectures.…”

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

“…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.…”
