The element required for solar energy conversion is?

The correct answer is Silicon.

• Solar Energy:
  • Under identical conditions, as compared to a white or a reflecting surface, a black surface absorbs more heat.
  • Solar water heaters and solar cookers use this property to work and hence these devices are useful only at certain times during the day.
  • Above limitation is overcome by the use of solar cells that convert solar energy into electricity.
  • Silicon is used for making solar cells, it is abundant in nature but the availability of the special grade silicon is limited.

Important Points

• Solar cells are used for many scientific & technological applications like artificial satellites and space probes like Mars orbiters as the main source of energy.
