Organic Dye Sensitized Solar Cells

Dye sensitized solar cells dscs are attracting much attention because of their relatively high conversion efficiencies low cost production processes and short energy payback time 1 in these devices sunlight is absorbed by photoactive molecules that are attached to the surface of a wide band gap semiconductor oxide typically tio 2 or zno forming a dense monolayer.

Organic dye sensitized solar cells. It is based on a semiconductor formed between a photo sensitized anode and an electrolyte a photoelectrochemical system. With an efficiency of around 11 and low cost production this technology has the potential to compete on the commercial market. Dye sensitized solar cells is a hybrid techonlogy and it is better than other techniques as the drawback are the low absorption of organic materials stability and liquid electrolyte. Novel boron dibenzopyrromethene dyes with thienyl cyanoacrylic acid units were synthesized and characterized for application in dye sensitized solar cells dsscs.

Dye sensitized solar cells are a hybrid organic inorganic technology that uses small molecule absorber dyes. This cell technology is currently amongst the most efficient third generation solar cells. The dyes feature intense absorption bands in the longer wavelength region with λ max values of 647 nm ε 1 57 10 5 m 1 cm 1 for 1 which has two anchoring units 660 nm ε 1 09 10 5 m 1 cm 1 for. 1 4 recently solar energy to electricity conversion efficiencies as high as 11 under am 1 5 g irradiation have been attained with dsscs.

Dye sensitized solar cells dssc have attracted considerable attention in recent years as they offer the possibility of low cost conversion of photovoltaic energy. A dye sensitized solar cell dssc dsc dysc or grätzel cell is a low cost solar cell belonging to the group of thin film solar cells. Usa home product directory materials science organic and printed electronics organic photovoltaic opv materials dye sensitized solar cell dssc materials materials science home materials science products. These dyes adsorb onto a suitable electron accepting material such as titanium dioxide or zinc oxide along with an electrolyte to regenerate the dye.

Dye sensitized solar cells are closely related to organic solar cells and belong to the thin films. This review focuses on recent advances in molecular design and technological aspects of metal free organic dyes for applications in dye sensitized solar cells. Over the last decade dye sensitized solar cells dsscs have attracted much attention because these unconventional solar cells exhibit high performance and have the potential for low cost production. 5 7 in dsscs the photosensitizer is one of the most.
