الملخص الإنجليزي

As a new technology, in the solar cell field, the dye-sensitized solar cell (DSSC) gives technically and economically practicable idea to develop the solar cell technology.

Dye solar cells used natural dye (pomegranate, strawberry, black tea, orange red, Grapefruit, Hibiscus sabdriffol, Borago officinalis) have been studied.

Pomegranate juice was chosen in this work as a natural dye because of its high conversion efficiency.

Furthermore ruthenium dye was adopted in this work as industrial sensitize dye because of its high efficiency over most industrial dyes.

Basic components of the dye solar cell which Studied, including electrodes types, type of dyes, electrolyte concentration and thickness of titanium dioxide, In addition to several improvers to increase the efficiency solar cell ,the best quality AgNO3.

The best conversion efficiencies obtained without any addition were 1.95% and 0.55% for ruthenium and pomegranate dye cells respectively ,while with addition of silver nitrate into the electrolyte, the conversion efficiency improved and become 3.7% and 1.2% for ruthenium and pomegranates dye respectively, the film thickness was (15 μm) and ruthenium dye concentration used in all the results were (5×10-4M).

Three types of experimental tests have been achieved (outdoor) using fixed, one-axis and two-axis tracking system was adopted in this study and the main difference among them is the ability to reduce the pointing error, increasing the daily irradiation incident to increase the energy output.

The study was conducted in the region (Baghdad – Al Jadiriya), line latitude (33.30) and longitude (44.140) .The two- axis system shows the best systems and least loss of out power between the three systems.
