_ cells are used in satellites and space vehicles.
Correct answer: B. Photo
- A. Electric
- B. Photo
- C. Positive
- D. Diode
Explanation
Solar cells are used in satellites and space vehicles. These devices, also known as photovoltaic cells, harness sunlight and convert it into electricity to power various systems and instruments onboard spacecraft. Solar cells are crucial in space applications due to their ability to generate electricity in the vacuum and harsh conditions of space without relying on traditional power sources.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
