Metasurfaces to Enhance the Efficiency of Solar Cells

CTCN Keyword Matches:

Researchers at Purdue University have developed new semiconductor applications called metasurfaces that improve the efficiency of light absorption in solar cells. Metasurfaces are extremely thin films of metamaterials assemblies that contain features patterns or elements such as tiny antennas or alternating layers of oxides that can greatly reduce interface reflection by enabling the control of air permittivity and permeability. These metasurfaces can be integrated into existing manufacturing processes which make them very practical for commercialization. Applications: Semiconductor solar cells


1) Increase the light-harvesting capacity of solar cells 2) Reduce the size and charging time of solar cells 3) Improved customization to meet a wider array of applications
