Photovoltaic | MCQs

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.

Explanation

Silicon is a semiconductor material crucial for converting sunlight into electricity in solar cells.

It is widely used due to its abundance and efficient photovoltaic properties.

Explanation

Solar PV cells generate electricity by absorbing sunlight and using that light energy to create an electrical current.

There are many photovoltaic cells within a single solar panel, and the current created by all of the cells together adds up to enough electricity to help power your home

Explanation

Solar cells, also known as photovoltaic cells, convert solar energy (sunlight) directly into electrical energy.

They work by using semiconductor materials to absorb photons from sunlight and release electrons, generating electricity.

Explanation

In photovoltaic cells, the current increases with the intensity of incident light.

More light intensity means more photons, which release more electrons, generating higher current.
