Role of ?-spacer in regulating the photovoltaic performance of copper electrolyte dye-sensitized solar cells using triphenylimidazole dyes

نویسندگان

چکیده

Two triarylimidazole organic dyes with an auxiliary donor (D–D–?–A) and accepter (D–A–?–A) were reported. The ?-spacer has significant role on physico-chemical photovoltaic performance of the [Cu(dmp) 2 ] 1+/2+ redox couples.

Acid azo dyes for efficient molecular photovoltaic: study of dye-sensitized solar cells performance

In this paper we sensitized three free-metal azo days Dye 1, Dye 2 and Dye 3 based on 1,8-naphthalimide with n-propyl as the electron donor group. We used sulfonic acid and hydroxyl substituents as the electron acceptor anchoring group in synthesized dyes. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions and characterized by different techniques...

Investigation of Photovoltaic Properties of 1,8-Naphthalimide Dyes in Dye-sensitized Solar Cells

In this paper we selected two metal-free dyes (Dye 1 and Dye 2) based on 1,8-naphthalimide. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions. Spectrophotometric measurements of the organic dyes in DMF and on TiO2 substrate were carried out in order to assess changes in the status of the dyes. Maximum absorption wavelengths for Dye...

The Construction and Comparison of Dye-Sensitized Solar Cells with Blackberry and N719 Dyes

In a dye-sensitized solar cell (DSSC), the amount of light absorption dependson the design of the pigments, which determines the strength of light absorption and theoptical range of the cell. In this paper, we have constructed and studied two fairly similarpattern of DSSCs in structure. The thickness of TiO2 used for both cells is taken to be 2μm. We have used an industrial N719 dye for one of ...

Synthesis and Application of Two Organic Dyes Based on Indoline in Dye-Sensitized Solar Cells

In this paper we sensitized two new organic days dye 1 and dye 2 based on thioindigo with phenothiazine as the electron donor group. We used acrylic acid and cyanoacrylic acid as the electron acceptor anchoring group in dye 1 and dye 2 respectively. The proposed dyes were sensitized from phenothiazine as the starting material by standard reactions and characterized by different techniques such ...

Enhanced performance of dye-sensitized solar cells using carbazole-substituted di-chromophoric porphyrin dyes

The purpose of this work is to investigate the origin of improved photovoltaic performance of a series of dichromophoric carbazole-substituted porphyrin dyes employed as sensitizers in dye-sensitized solar cells. Five di-chromophoric zinc porphyrin dyes with the same porphyrin core, a carbazole unit attached in the mesoposition through a phenylethenyl linkage, and substituents spanning a range ...
