today i want to share how to make a solar cell at home easily and it is fun to make.but firstly i want to tell you dont expect to light your house with these solar cells because it produces small voltage and may need acres of them to power the house!but yet it is easy and need ordinary stuff .but little caution is needed to handle and make the cell.it is great for science classes and projects

visit my profile:http://www.instructables.com/member/argha+halder/ to see some more of such interesting projects.

Step 1: things needed:

the things you will need:
1)gas or electric stove 
2)copper plate or flashers -2
3)a transparent plastic or glass container
4)some wire
5)some water
the tools you will need:
1)voltmetre(just for testing)
3)soldering iron

This is great. I can't wait to try it myself. Perhaps I could run it back to a lithium battery and see if it recharges?
<p>The wire has to be positive or negative?</p>
I did not completely understand your question, but in case you wanted to know the polarity of the wires, the wire from the burnt copper is negative and the wire from the regular copper is positive. I hope it helps :)
<p>Can I turn up a lightbulb with this proyect, if i put alot of cells together can i ?</p>
you could, but to light up a l.e.d light you will probably need 6-7 of those cells. and what is the point of lighting up a light bulb using the light from the sun??
<p>both ccopper plats are in burren state .how joule theif work or help in making mor voltag</p>
sorry for the late reply. so only one of the copper is burnt. Joule thief circuit is a voltage booster. so adding the Joule thief would increase the voltage of the output at the cost of ampere...
<p>Dude both cells are burned?</p>
<p>No, only one of the copper plates are burned. </p>
<p>I love this instructable thank you so much</p>
<p>Welcome!! It would be my pleasure if it helped you!!</p>
<p>its good but producing tooo small voltage how to increase it </p>
<p>You might make many of them and attach them in series, or you can put a lense on top of it so that you get brighter light,, etc.. You might be creative and find out some ways by yourself!!</p>
You could connect many cells in serie to get more volts. <br>What if you bring the electrodes closer?
bringing the electrodes closer can increase only a few nano or mili volts.
HOw can we bring the electrodes closer ?? <br>
you will just need to build the cell in a smaller plastic cylinder or anything. if the jar is smaller it will eventually decrease the space between the electrodes . so it will bring the electrodes closer. <br>
thanks !!!
Simply bring them closer. They don't need to be near the wall of the container. You could place a grille separator between both, like the car batteries have. This avoid its accidental contact.
thanks !!
But you will gain surely a lot of milliamperes. You need more mW, and Watt = Amp * Volts
oh then thanks for the suggestion!
Thanks for saying cell and not panel as panels heat water
yeah, that what used to make me confused, i looked for cell, but mostly i found panel, so i decided not to make such mistake.
Very Cool!
Nice instructable. I'm very interested in making new improvements to see if I could get it to produce more electricity.
thanks.oh and if you want to increase its voltage then use a bigger cuprous oxide that is the heated copper.then use a voltage step up converter.or use many cells together
