The document outlines a series of activities conducted by students to explore the potential of dye-sensitized solar cells (DSSCs), including investigating photosynthesis, separating leaf pigments, measuring solar cell performance, and constructing a solar cell. The project emphasizes the development of a solar heater that leverages DSSCs to provide clean energy for various applications, particularly beneficial for Qatari families during weekend outings. Acknowledgments are given to teachers and sponsors who supported the team's research and development efforts.

- 2. OUTLINE • 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: The : Solar heater works on solar power , produces clean energy and easy
- 3. INTRODUCTION A dye-sensitized solar cell (DSSC) is a low-cost solar cell belonging to the group of thin film solar cells.
- 4. ACTIVITY 1: INVESTIGATING PHOTOSYNTHESIS OF PLANT DISKS Objective: We learned that the photosynthetic rate is different with different colors. Cutting paper mint Keep paper mint lump inside the syringe And then put it in distilled water We took the yellow slide to see the amount of light absorptive In the end we got the results

- 6. ACTIVITY 2: SEPARATING LEAF PIGMENTS USING PAPER CHROMATOGRAPHY Objective: We use the dye solution to separate the dyes Tools used in the activity Copy the dye on paper Keep paper chromatography in the dye solution
- 7. ACTIVITY 2: SEPARATING LEAF PIGMENTS USING PAPER CHROMATOGRAPHY Conclusion: Chlorophyll has four dyes, green, orange yellowish, yellowish green, yellow 40 35 30 25 20 15 10 5 0 Chlorophyll d Chlorophyll c
- 8. ACTIVITY 3: MEASURING A SOLAR CELL PERFORMANCE Objective: Measuring a solar cell performance

ACTIVITY 3: MEASURING A SOLAR CELL PERFORMANCE 0.75 Distance from light vs voltage 1 1.3 1.56 1.8 1.6 1.4 1.2 1 0.8 0.6 0.4 0.2 0 30 20 10 5 voltage Distance in centimeters We found that the a solar cell supplies about 1.5 volts and 8 mile amperes under a 75 watt light bulb. And the resistance has been calculated to 0.8 ohms

- 12. SOLAR HEATER As you know that the Qatari society likes to spend the weekend in the mainland, and this is the idea of our project in the energy that you need to spend the Qatari family needs in such leave, the provision of our product provides the raw material in the production of electricity as fuel, diesel fuel. Solar Geyser: The idea is to use solar cells to absorb sunlight and convert it to energy and stockpiled in batteries, and can use the ideas of the solar heater: - First: Connect thermal wire with batteries and when they pass the electricity in the wires heat up and help in cooking. The second: output to an electric current can be used to charge the "laptop" or a mobile phone and etc.
- 13. SIGNIFICANCE OF THIS PROJECT cardboard box solar ovens make a great summer project for the family. Not only are they fun to make, but they are also fun to make food in. You get to use an all natural source - the sun! This project aims to: provide clean energy to be available and easy to transport, use and provision of raw materials, fuel, diesel, and the conversion of solar energy into electrical.
- 14. Hypothesis Hypothesis: Our project (Solar Geyser) if developed and increase the amount of solar panels and efficiency may obviate the electricity generator used by the Qatari family in the mainland in the weekend, and the coal used in cooking.
- 15. METHODS AND MATERIALS We use(dye-sensitized solar cell)to put it in the solar heater Our teams between (dye-sensitized solar cells) and(silicon solar cells)and we preferred (dye-sensitized solar cells)because they are less cost
- 16. SOLAR HEATER RESULTS:- Used in solar geyser of camping with the family or when you go to the beach We have managed to solve the problem (the provision of raw materials and the production of clean energy at the lowest cost)
- 17. SOLAR HEATER RECOMMENDATIONS :- We recommend expanding the project uses, where it is used in the operation of the television or video games (PlayStation) We recommend that the development of solar cells where the largest amount graduated from voltage
- 18. CONCLUSIONS In the end Al-bairaq experience was more than a great experience and we learned a lot, especially about photosynthesis.
