Explanation

Inverters and rectifiers are electronic circuits that can change the type of electric current.

An inverter converts DC to AC,

while

a rectifier converts AC to DC.

Explanation

The element required for solar energy conversion is silicon.

Silicon is the most common semiconductor material: Silicon is used in about 95% of solar cells sold today. 

Silicon is a naturally occurring element: Silicon is the second most abundant element on Earth, after oxygen.
