DIY solar battery made from diodes

Making a real solar battery at home is almost impossible. To do this, you need not only specialized factory equipment, but special chemicals that cannot be found so easily.
But if you suddenly really need it, you can build a low-power solar battery from diodes.

I will build a solar panel that will produce two volts of voltage and half an ampere of current. By connecting such a solar battery to a boost converter, in bright sunshine, it is quite possible to charge a cell phone. To do this I need 100 silicon diodes in a glass case. I had just a hundred diodes on hand.
I took packages of diodes.


And without pulling it out of the tape, I began to tamper with the output of the contacts.


Then, he began to connect in parallel in groups of 11 pieces. And I have already connected these groups in series.



In the end this is what happened:

Next, I glued these “rails” to a wooden backing with super glue.

I cover the reconciliation with pre-cut, thin plexiglass. And I secure it with self-tapping screws.

That's all. It took half an hour to do everything about everything.

Solar battery tests

Connecting multimeter to the exit and point the panel towards the sun.

It turned out - “1.7”

I close it with my hand and the voltage immediately drops.
I played some more and it turned out to be almost two volts.

A homemade solar battery is quite functional.
