Dye Sensitized Solar Cells Are Made From Which Organic Dye

Application of natural dyes is a promising development in the.

Dye sensitized solar cells are made from which organic dye. In 1991 professor grätzel et al. 5 7 in dsscs the photosensitizer is one of the most. The solar cells presented by demadrille and his colleagues were fabricated using photochromic dyes. 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.

International journal of engineering technologies adedokun oluwaseun et al vol 2 no 2 2016 34 review on natural dye sensitized solar cells. Arylamine organic dyes with donor d π bridge π and acceptor a moieties for dye sensitized solar cells dscs have received great attention in the last decade because of their high molar absorption coefficient low cost and structural variety in the early stages the efficiency of dscs with arylamine organic dyes with d π a character was far behind that of dscs with ruthenium ii. It is based on a semiconductor formed between a photo sensitized anode and an electrolyte a photoelectrochemical system. When solar cells are sensitized using these dyes they acquire the same color changing properties.

Moreover dsscs based natural dyes have been reported in the previous studies. Made a breakthrough 7 cell efficiency on dye sensitized solar cells dsscs thus facilitating the intensive investigation on this type of solar cells which were considered as one of the most potential renewable power sources because of their remarkable advantages such as simple fabrication processes in ambient conditions semi transparent and. Now a days study of dyes extracted from natural resources is the main concern for researchers. Dye sensitized solar cell converts visible light into electricity using sensitization of the cell.

Performances of dye sensitized solar cells are mainly based on dye used as a sensitizer. The most efficient dye sensitized solar cell uses ruthenium complexes and metal free organic dyes as a dye 19 22. 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.
