HOW TO
CREATE DIY SOLAR CELL
Heres the
equipment and all material that you might require to find :
2 Binder
clips (to hold the plates together), this binder clips will be use to hold the
two side glass, we are using the binder clips for easy to release or attach the
slide.
Acetone or
rubbing alcohol, you may use actone or Iso Propanol, or any other organic
solvent to remove any organic matter on glass.
Glass
Plates, you need conductive glass, you may bought or create your own conductive
glass using the following link :
Parafin
Candle, you may require a paraffin candle to make Carbon Side electrode, but
this part can be replaced with graphite.
Multi meter, you need multimeter, the tester
shall be able to measure the resistivity up to 30 Ohm, and also able to measure
voltage below than 1 V, preferable.
Cottong
Pads, this thing will be use as a wiper to remove any exceed solution of side
electrode.
Demin water
(de-mineralized water), please use low conductivity water.
Raspberry, blueberry or blackberry juice (has
to be made directly from the fruit! no processed juices!)
Iodide solution
Cooktop/hotplate
STEP :
A.
Preparation of titanium oxide side
1.
Clean up conductive side glass using acetone
2.
Dilute titanium oxide using water slowly, make
it slurry, titanium oxide will not fully solved into water.
3.
Pour titanium oxide slurry into conductive side
glass, tidy up the surface of slurry.
4.
Heat up the glass for a few hour until the
titanium oxide baked on glass side.
5.
Crush up some berry and gently put titanium
oxide glass into it.
6.
Let the titanium oxide soaked into 10 minute.
7.
Clean up the the titanium oxide glass with demin
water.
B.
Preparation of Carbon Side.
1.
Light up the paraffin candle.
2.
Gently heat up the conductive side, so you can
find carbon rest on the side glass.
3.
Repeat the step until you get all the side are
covered up with carbon.
C.
Assembling
the solar cell.
1.
Attach those two side of glass using paper clip.
2.
Pour a few drop of iodide solution.
3.
Solar Cell ready to be used.
