Check out our new paper in Advanced Materials where we demonstrate 2.8-micron thin crystalline silicon solar cell with an 11.2% efficiency using a metasurface for broadband light trapping and antireflection. Delicate design of multiple Mie resonances across the solar spectrum combined with engineered diffraction channels enable highly efficient light absorption. At the same time, the nanotextured silicon surface exhibits uniquely good surface passivation using a thin conformal oxidation layer.

Congratulations Juliette!!
