6. Solar Cells Background Innovation Features and Benefits Conclusion
Photons in sunlight hit the solar panel and are absorbed by semiconducting materials.
This excites the electrons of the semi conducting material and creates an electric charge.
The International Energy Agency projects that by 2050, solar power will contribute 16 % of the world’s electricity
Two types of solar cell: Silicon and Perovskite
