  2. Gallium Arsenide

  3. Cadmium Telluride

  4. Copper Indium Gallium Selenide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Silicon is commonly used in the production of solar panels. It is a semiconductor material that absorbs sunlight and converts it into electricity.

Multiple choice

What is the name of the process by which molecules are broken apart by high-energy radiation in space?

  1. Photodissociation

  2. Recombination

  3. Ionization

  4. Dissociation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photodissociation is the process by which molecules are broken apart by high-energy radiation, such as ultraviolet light, in space.

Multiple choice

What is the phenomenon responsible for the generation of an electric current in a photovoltaic cell?

  1. Photoluminescence

  2. Electroluminescence

  3. Photovoltaic effect

  4. Fluorescence
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In a photovoltaic cell, the generation of an electric current occurs through the photovoltaic effect, where the absorption of light energy by a semiconductor material creates an electron-hole pair, leading to the flow of current.

Multiple choice

Which of the following materials is commonly used in the production of solar cells?

  1. Silicon

  2. Gallium arsenide

  3. Cadmium telluride

  4. Copper indium gallium selenide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Silicon is the most commonly used material for the production of solar cells due to its abundance, low cost, and high efficiency.

Multiple choice

What is the primary mechanism responsible for mass loss in the solar wind?

  1. Radiation pressure

  2. Magnetic pressure

  3. Thermal pressure

  4. Gravitational pull
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In the solar wind, magnetic pressure from the Sun's magnetic field lines drives the outward flow of material.
