Done by Gold 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. The use of solar cell in sea water desalination using electricity for heating sea water and separating salt from the fresh water

3. Introduction
In this experiment we will use mint
plant leaves strips to measure which
light color will affect photosynthesis
rate the most. You will use different
colors.
Controls: sodium bicarbonate
concentration in water, temperature,
amount of water, light intensity, and
size of leave strips.
Variables: color of light.

4. Activity 1: Investigating Photosynthesis
of Plant Disks
We cut small pieces
from mint leaves
we put it with
titanium dioxide we
put it under the
light after that
observe result

5. Activity 2: Separating Leaf Pigments
Using Paper Chromatography
We put a
chromatography
solution in a small cap
then we put it in a big
slender then we put a
strait paper and we
wait 30 min and then
we saw a colour in the

6. ACTIVITY 3: MEASURING A
SOLAR CELL PERFORMANCE
We measured the voltage using
multimeter
under light .
And then calculate resistance usibg
formula.
R=V/I

7. Activity 4: Making a Dye-
Sensitized Solar Cell
We mix titanium dioxide with vinegar
Then we put it on small glass slide
Then we heated by 450 degrees
After that we put it in a dye
We put under the slide a candel to geat a carbon
We put tow glass together we put electrolight
betwen each glass

8. Project Idea: Sea water
desalination
The use of solar cell in sea water
desalination using electricity for
heating sea water and separating salt
from the fresh water
