A patented breakthrough by researchers at the Technion-Israel Institute of Technology improves the efficiency of organic photovoltaic cells by 50 percent, and could someday provide a huge boost for the viability of solar power as a major source of energy. The researchers recently published their findings in the Journal of Applied Physics.
Organic photovoltaic cells convert solar energy into electric power through organic molecules. One of their advantages over "traditional" solar cells made of silicon is that they can be mounted on lightweight, flexible, and easy-to-replace sheets, which can be spread on roofs and buildings like wallpaper, converting solar energy into electrical current. In the future, they could also be used to provide a cost-efficient and reliable source of electricity in isolated regions.
