The drastic reduction of global CO2-emission with contemporaneously high supply reliability requires strategic changes in the design of future energy system. Renewable energies have a long-term potential to take over the entire global energy supply. National Renewable Energy Laboratory lab tests using CdTe material achieved some of the highest efficiencies for solar cell electric power generation. The future challenge is the integration of the promising nanotechnological approaches into technical innovations for the development of a sustainable energy supply using one dimensional Tellurium.
