| Consider the following statements about 'Quantum Dot' solar cells: |
| 1. Researchers from the University of Toronto created a solar cell out of inexpensive materials that was certified at a world record 7% efficiency. |
| 2. The new solar cell designed are called quantum dot films, leading to the most efficient quantaum dots solar cell ever and it has a smaller size in (nanometers). Which of the statement s) given above is/are correct? |
A) Only 1
B) Only 2
C) Both 1 and 2
D) neither 1 nor 2
Correct Answer: C
Solution :
[c] Quantum dot solar cells are an emerging field in solar cell research that uses quantum dots as the photovoltaic material, as opposed to better-known bulk materials such as silicon, Copper Indium Gallium Selenide (CIGS) or cdte. A Quantum dot is portion of matter (e.g. semiconductor), whose excitons are confined in all three spatial dimensions. The term quantum dot was coined by Mark Reed.
