Solar And Fuel Cell Technology Ppt

The solar cell works in three steps photons in sunlight hit the solar panel and are absorbed by semiconducting materials such as silicon electrons negatively charged are knocked loose from their atoms causing an electric potential difference.

Solar and fuel cell technology ppt.

Solar cells are a promising and potentially important technology and are the future of sustainable en ergy for the human civilization. India is endowed with vast solar energy potential. The software program titan has actually started examining hydrogen fuel cells as a back up source of power at one of its u s. The excitement surrounding hydrogen fuel cells shouldn t come as a surprise.
