Dye sensitized solar cells (DSSC) are a promising technological alternative to conventional pn-junction solar cells, and therefore attract considerable scientific interest. Different attempts have been made to replace the liquid electrolyte by a solid state hole conducting organic or inorganic medium. This contribution compares electrical properties of three different types of DSSCs. First, we ...

Background Grätzel solar cell, also known as dye-sensitized solar cell (DSSC), is a dye-sensitized nanocrystalline photovoltaic cell of TiO2 (titanium dioxide). It has a surface of nanoporous TiO2, a semiconductor of a wide bandgap. The basic principle is to transform light energy into electrical energy. When a dye molecule absorbs light, an electron is replaced by an excited state, and this dy...

The development of clean and renewable energy sources reflects the limited fossil resources and severe environmental problems caused by their combustion. Infinite and inexhaustible solar energy is a key resource to meet a rapidly increasing global demand for energy. Dye-sensitized solar cells (DSSC) are promising devices to generate clean energy as an alternative to the traditional solar cells ...

1.1 New type of solar cell: dye-sensitized solar cells (DSSCs) The rising price of fossil fuels, together with their rapid depletion and the pollution caused by their combustion, is forcing us to find sources of clean renewable energy. Fortunately, the supply of energy from the sun to the earth is gigantic, i.e., 3 × 1024 joule a year or about ten thousand times more than what mankind consumes ...

A vertically aligned carbon nanofiber array coated with anatase TiO(2) (CNF/TiO(2)) is an attractive possible replacement for the sintered TiO(2) nanoparticle network in the original dye-sensitized solar cell (DSSC) design due to the potential for improved charge transport and reduced charge recombination. Although the reported efficiency of 1.1% in these modified DSSC's is encouraging, the lim...

Sensitizers are responsible for the light harvesting and the charge injection in dye-sensitized solar cells (DSSCs). A fast dye-regeneration process is necessary to obtain highly efficient DSSC devices. Herein, dye-regeneration rates of two DSSC device types, that is, the reduction of immediately formed photo-oxidized sensitizers (ruthenium complex C106TBA and porphyrin LD14, k(ox)') by iodide ...

In this study, we fabricate a counter electrode by coating Pt ribbon onto fluorine-doped tin oxide glass substrate with layer. The gives rise to protrusive structure of the electrode, produced photolithography, sputtering and lift-off processes. experimental results reveal that photoelectric efficiency dye-sensitized solar cell (DSSC) (5.32%) is 21% higher than DSSC without (4.38%). This infers...

Since dye-sensitized solar cells (DSSCs) appeared as a promising inexpensive alternative to the traditional silicon-based solar cells, DSSCs have attracted a considerable amount of experimental and theoretical interest. In contrast with silicon-based solar cells, DSSCs use different components for the light-harvesting and transport functions, which allow researchers to fine-tune each material a...

Abstract Nowadays, the development of science and technology has been increasing demand for energy. Energy problem become a bottleneck to restrict international social economy. People pay more attention research renewable resources. Solar energy is kind resource with great potential no pollution. The commercialized solar cells are mainly silicon cells, among which conversion efficiency single h...
