Question

Q.The efficiency of a solar cell may be
in the range

A.2 to 5%
B.10 to 15%
C.40 to 50%
D.70 to 80%
Q.The following technique is employed
to form a pn-junction diode

A.lon implantation
B.Diffusion of dopants
Epitaxial method.
C.All the above​

Answer 1

Answer:

10-15%

Explanation:

Answer 2

The answers are Option B) 10 to 15% and Option D) All the above.

• Most solar cells have an efficiency of under 20%. The average efficiency of a solar cell ranges from 10 to 15%. Few solar cells have higher efficiencies but they are only tested in the lab so far.
• Diodes are made using methods like Ion Implantation, Diffusion of dopants, Epitaxial method etc. and hence the answer is all the above.
