Identify the devices which work on solar energy. (a) Photodiode (b) Photovoltaic cell. (c) LED (d) Photo thermal devices.

Options

  1. A(a), (d)
  2. B(b), (d)
  3. C(a), (b)
  4. D(b), (c)

Correct answer

B. (b), (d)

Step-by-step solution

Concept based. Photovoltaic cells produce electrical energy by absorbing solar energy. Same is true for photo-thermal devices. Photodiode produce electrical signal by absorbing photon's and LED's use electric energy to produce photons.
