High Performance Solar Concentrator Developed

摘要

In pursuit of the SunShot Initiative's goal to drive the cost of solar-generated electricity down to 6 cents per kWh, the DOE's National Renewable Energy Laboratory (NREL) has designed a new solar cell that converts electricity at 45.7% efficiency. With one of the highest photovoltaic research cell efficiencies ever achieved, the new design incorporates an extra absorber layer to achieve the boost in efficiency and is designed to receive more than 1,000 suns of concentrated sunlight.
