Abstract

Sunlight is a renewable (sustainable) source of energy that is free from all kinds of environmental pollution. According to the world's interest in renewable energy, especially in 2020, it has become the main target of many projects. Egypt is considered a “sun belt” country of an average solar energy from 2,000 to 3,000 kWh/m2/year of direct solar radiation as stated in Egypt’s Solar Atlas. This means that every square meter in Egypt gets annually from 2,000 to 3,000 kWh per year.
Solar cells fabrication has passed through lots of improvements throughout generations. These developments are basically hindered by efficiency and high cost. Dye Sensitized Solar Cell (DSSC) is an inexpensive type of solar cells. In this project, a model of dye sensitized solar cells was fabricated using local and cost effective materials. The cost of the modified cell is 95% cheaper than that before modification. The main reason for that is using Soda-Lime glass coated with conductive type of polymer instead of the expensive FTO glass. A modified cell is fabricated with an area of 16x15 cm2. The total voltage then is about 560 mV. Although the efficiency of the modified cell is less than that before modification, but now it is available for any country to easily apply such project with affordable price.
