Done by Engineers group, Doha Independent secondary school for boys Dye-Sensitized Solar Cells (DSSC) is a low-cost solar cell belonging to the group of thin film solar cells. Fossil fuel will not stay forever so why don’t we make use of the Solar Energy. We thought about using DSSCs in Qatar metro DSSCs will be on the surface of the metro and also on both sides to absorb maximum amount of solar energy Solar panels will also be placed in the train stations and supplied by them.

2. • Introduction
• Activity 1: Investigating Photosynthesis of Plant Disks
• Activity 2: Separating Leaf Pigments Using Paper
Chromatography
• Activity 3: Measuring a solar cell performance
• Activity 4: Making a Dye-Sensitized Solar Cell
• Product Idea: Green Train in Qatar

3. DSSC (dye-sensitized solar cell) is a low cost solar cell belonging
to the group of thin film solar cells it is based on a
semiconductor formed between a photo sensitized anode and
an electrolyte.

4.  Objective : Investigating Photosynthesis .
 Cut leave Disks
Soak Into Sodium Bicarbonate
 Put Under light and Wait

Current=10 mA

12. Introduction: Trains consume large amount of
energy, cost a lot of money, and cause huge pollution in
the world
We can decrease these problems by many ways.

14. Hypothesis:
Our project is save on the environment .
Plenty of solar energy is available in Qatar .
Our project materials are available and not costy .

15. DSSC Materials :
 Titanium dioxide
 Vinegar
 Carbon
 Electrolyte
 Dye
 Glass slides
Wires
Tools(ex. Multi-meter)
Electric circuits & boards
Lamps

16. o Find a safe alternative for the fossil fuel .
o Make good use of the renewable energy (solar energy).
o Save cost and materials .
o No negative impact on the environment.
o Contribute in Qatar 2030 .

17.  We wish we could do more researches to get more energy from Dye-
Sensitized Solar Cell and use it in more than one field other than trains.
 Thus , we can make the life more safety .
Conclusions:
 Make trains work with Dye-Sensitized Solar Cell will make Qatar
predecessor for other countries and it will help Qatar community
even in the whole world.

18. Many thanks to my teachers, school and AL-Bairaq team from Center for
Advanced Materials (CAM), Qatar University for supporting us during our journey
with a AL-Bairaq.
Also, I would like to thank the sponsors UNESCO, Ras Gas, Maersk Oil and Shell.
