Wide-band-gap semiconductors could harvest sunlight underwater
Blue and yellow light (400-600 nm), in contrast, is less easily absorbed by water, which means it can penetrate further below the surface. To Röhr and his colleagues in André Taylor’s Transformative Materials and Devices Lab at NYU’s Tandon School of Engineering, this suggested that semiconductors with wider band gaps could be a better “fit” for supplying energy underwater, he says.
