The hole transporting medium in solid-state dye-sensitized solar cells can be utilized to harvest sunlight. Herein we demonstrate that a triphenylamine-based dye, used as hole-transporting medium, contributes to the photocurrent in a squaraine-sensitized solid-state dye-sensitized solar cell. Steady-state photoluminescence measurements have been used to distinguish between electron transfer and...

A pyrene photoluminescent layer is coated on the front side of a dye-sensitized solar cell to enhance the power conversion efficiency. The power conversion efficiency of the dye-sensitized solar cell coated with a pyrene photoluminescent layer improves from 9.12 ± 0.06% to 10.30 ± 0.11% (an improvement of 12.94%).

The dye-sensitized solar cells (DSSC) have been regarded as one of the most promising new generation solar cells. Tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. In this review, various characteristics of dye-...

Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode  generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes  have shown significant properties such...

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 ...

Dye sensitized solar cells (DSSCs) are considered as one of the most promising alternativerenewable energy sources. In the structure of DSSCs, a photosensitizer composed of transitionmetal complexes is used to harvest light. In this work a binuclear complex containing twopropionitrile pendant arms [ZnLCu(OAC)]PF6 {L = 1, 6- bis (2-cyanoethyl) -2, 5-bis (2-hydroxy3-formyl-5-methylbenzyl)-2, 5- d...

Oxide nanocrystallite aggregates are candidates for use in dye-sensitized solar cells. The aggregates are of submicron size, formed by nano-sized crystallites and, therefore, able to offer both a large specific surface area and desirable size comparable to the wavelength of light. While used for a photoelectrode in a dye-sensitized solar cell, the aggregates can be designed to generate effectiv...

in order to fabricate transparent tio2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from ti substrate by a re-anodization method. the membranes are transferred on fto glass by two different methods. at the first one, 100mm ti-isopropoxide is used to make tio2 nanoparticles for adhering tio2 nanotube membranes to fto and in the second one a commercial ti...
