How to make solar panel / solar cell at home

In this video i will make a solar panel at home in diy method.
You can make the silicone by adding solvent with pure silicone powder.
Maximum current 20mA.
After few hours the cell stopped working.
So, don’t attempt to make it.
Solution used to etch the copper was Ferric Chloride. (FeCl3)
1 spoon in half litre water.
Be careful to use the solution.
Don’t throw the waste in drainage.
Eatching took about 10 mins.
*Try at your own risk.


  1. I think this cell acted as more of a copper/zinc battery lol. The life of this will be very limited. Nice build though, and amazing lines!

  2. Boron and phosphorus have to be infused with monocrystaline silicone to get any voltage. They have to be cut in a single sheet or they will not work. You are not even using real silicon. Great job in waisting my time and making me feel stupid 👍

  3. I’m sure that in 1985 ferric chloride solution is available in every corner drug store but in 1955 it’s a little hard to come by

  4. Just buy some LED's. Cheaper than this and put out more current. Not too many people seem to realize you used the edge of the PC board to draw those lines straight. I do that all the time.
