I am a truly surreal element, what with my properties being absolutely science-fictional and all! 

 As you probably know, most metals conduct electricity, that's why you use copper wire in your telephones and other electronic devices. If you hold my in a dark closet I'll conduct electricity as well as a rock will conduct a train, but bring my out into broad daylight and a miracle will take place. I will convert from a non-conductive material into a conductive material! This property is used in electronics that detect or respond to light.

I can also produce electricity from sunlight, and so I'm applied in solar panels and other like products.

Thank you for your time, it was truly wonderful!
