چکیده:
The dye-sensitized solar cell was fabricated using discarded mobile phone. The recycled mobile screen was used as counter electrode. In the fabrication process, the use of recycled materials promotes eco green energy and alternative source for dye-sensitized solar cells (DSSC). The ITO substrate was used as photoelectrode growing zinc oxide (ZnO) by hydrothermal growth. The natural plant Alkanna tinctoria root extract was used as photosensitizer and N719 was used as reference dye. The power to conversion efficiency achieved as 0.0244% by natural plant Alkanna tinctoria root. The aim of this study is to develop a culture of using recycled items toward eco green energy production as well as research work may also be carried out by these discarded mobile screen as photo and counter electrode.

Biradar and Ramesha (2014) used Syzygium cumini extract as photosensitizer over ZnO based DSSC and achieved PCE 0.
1. Natural plant dye preparation The Alkanna tinctoria roots was washed several time under tap water and ensured no more mud particles remained, than washed with deionized water many times for removing remaining impurities and dried with hot air at room temperature for two hours.
The two different ITO substrate as photoelectrode were sensitized with natural plant extract Alkanna Tinctoria roots and dye N719 (Di-tetrabutylammonium cis-bis (isothiocyanato) bis (2, 2′-bipyridyl - 4, 4′- dicarboxylato) ruthenium (II) by Solaronix for overnight respectively.
3. RESULT AND DISCUSSION The UV absorption spectra of natural plant Alkanna tinctoria root extract used as dye illustrates in figure1.
