New Solar Materials and Efficiency
Newer breakthroughs in Solar materials are becoming a reality as we speak. Several new materials are being made right now. A thinner wafer also being formed. And with thinner means less material and much lower costs.
Also an idea is being formed with a mirror reflector inserted behind the solar cell to bounce back more light into the cell.
This results in increased efficiency and much more powerful cell. All this at a much lower cost. Knowing these facts gives us extreme promise of a future solar world. More solar means less dependency on fossil fuels, gas etc. A much cleaner way to conduct power and electricity.
