FACTORS CONTROLLING TRANSPARENCY TO THE EFFICIENCY OF PHOTOVOLTAIC RATION BY SUITABLE DYE SELECTION USING DYE SENSITIZED SOLAR CELLS

Abstract

Dye synthesized solar cell (DSSC) is a great promising inexpensive renewable source of energy that have a big profile of application specially the transparent solar cell. Transparent DSSC is the core focus of this paper. The transparent solar cell was prepared using titanium dioxide (TiO₂) nanoparticles as a counter electrode. The method for depositing TiO₂ is screen printing. The design of the solar cell followed the traditional way containing Fluorine doped Tin Oxide (FTO) glass, TiO₂, electrolyte, Platinum (PT) as a counter electrode, and N719 day. The results indicated that the thickness of TiO₂ thin film is 2.926 [µm] and 75% transparency before the assembly of the whole cell. On the other hand, the achieved transparency of the solar cell after the assembly was 70% and the efficiency is 3% using screen printing. This paper studies the variables that affect the transparency and the efficiency at the same time and suggest ways to improve the quality of transparent solar cell by selecting a suitable dye.
