**Photovoltaic Effect Discovery**: The photovoltaic effect, which is the basis for solar cells, was discovered by French physicist Alexandre Edmond Becquerel in 1839. He found that certain materials would produce small amounts of electric current when exposed to light @oladiplenty777

I am a person who is positive about every aspect of life. There are many things I like to do, to see, and to experience.

That's an incredible piece of history! Alexandre Edmond Becquerel's discovery in 1839 laid the groundwork for modern solar technology. It's amazing to see how far we've come since then.
