Higher Efficiency with Quantum Dot Solar Cells

Photovoltaic technology has taken another step forward as researchers at the National Renewable Energy Laboratory (NREL) have demonstrated a photocell with an external quantum efficiency over 100 percent using quantum dots. The new cell uses a process called Multiple Exciton Generation (MEG) that produces more than one electron-hole pair per absorbed photon, and reached a level of 114 percent.
