Every hour, the earth receives enough energy from the sun to cover our total annual energy usage!
The direct use of solar energy will be a main pillar of a sustainable energy supply system. The technological challenge lies in making solar cells that produce electrical energy to a lower cost.
SINTEF Materials and Chemistry is working with the technological challenges in producing solar cells with:
• Higher efficiency
• Less consumption of material
• Thinner wafers
• Cheaper feedstock
• Building integration
