HEY MATE HERE IS YOUR ANSWER:-

(i) Solar concentrates increase the efficiency of solar energy devices.

ANS.Solar cell performance is directly linked to the efficiency of converting sunlight into electricity. ... Conventional solar cells only absorb a narrow range of wavelengths very efficiently. The energy at other wavelengths is not absorbed at all or is converted into waste heat rather than electricity.

(ii) hydrogen as a source of energy,is associated with many technical constraints​

ANS.It’s a fact that hydrogen energy is a renewable resource because it’s abundantly available and its impacts hugely neglected. However, hydrogen companies will, in real sense, need other forms of non-renewable energy such as fossil (coal, natural gas, and oil) to separate it from oxygen. We may be able to minimize over-reliance on fossils fuels when we embrace hydrogen energy, but it will be daunting to get rid of it from the system.

Reason on solar concentrates increase the efficiency of solar energy devices:

  • The solar energy is the energy obtained from the sun in the high axis of prior.
  • These solar energy has a different axis of radioactive ness.
  • The solar energy to the earth is obtained in the form of different axis, in solar cells.
  • This serves as the key for collecting the energy from the solar radiation.

Hydrogen as a source of energy, is associated with many technical constraints:

  • The hydrogen is the better source of energy.
  • This atom of hydrogen is concentrated in the formation of many many applications.
  • And it has many technical content associated with it.
