How long does it take to make a solar cell?
It only took me 1 day because I had all the required materials ready before I start to make it.
If you decide to make it by yourself, it will take you very long.
It is now mass produced, so it doesn't take long to make it in the factory.
Solar cell requires the sunlight to be made eventually, so if it's not sunny at all, it will take you much longer than you thought.
