NEXT GENERATION SOLAR CELL THAT CAN CAPTURE NEARLY ALL ENERGY OF SOLAR SPECTRUM

NEXT GENERATION SOLAR CELL THAT CAN CAPTURE NEARLY ALL ENERGY OF SOLAR SPECTRUM

Researchers developed a multijunction solar cell on a GaSb substrate that can efficiently convert the long-wavelength photons typically lost in a multijunction solar cell into electricity. This prototype cell has an efficiency of 44.5% which is higher than conventional solar cells. A GaAs-based cell is stacked mechanically with the GaSb-based materials to create a four-terminal, five …
