Alternative energy source is needed for next generation due to the shortage of Fossil fuels in world. Some alternative energy sources such as hydroelectricity or wind are limited to areas with windy environments or flowing rivers. On the other hand, sun allows all parts of the world to use its energy. Solar energy is not only environmentally safe, but also a source of energy that will exist for billions of years. Dye sensitized solar cells (DSSC) technology attracted the researcher for its low-cost, high-efficiency solar-to-electricity conversion. An investigation was conducted to study of the effects of blackberry dye (syzygium cumini), a seasonal fruit in Bangladesh as a sensitizer. In this work we have constructed a DSSC where we have used nano particle TiO2 as the wide band gap semiconducting oxide. To sensitize the oxide we have used a natural dye extracted from blackberry (syzygium cumini). As the counter electrode we have used photosensitive materials carbon. We also have used an iodide/tri-iodide couple electrolyte solution in the solar cell as a charge carrier.
