Transparent amorphous-silicon solar cell lets in more than 60% of visible light

Scientists in Spain have developed an amorphous-silicon solar cell that could be used in both transparent photovoltaics and tandem applications. The device reportedly achieves notable efficiency levels and may offer an alternative to transparent organic photovoltaics.A research group from Spain's Universitat Politècnica de Catalunya (UPC) has fabricated a transparent solar cell based on a light absorber made of amorphous hydrogenated silicon carbide (a-Si1-xCx:H) thin films. "Our cell shows an outstanding transparency of over 50% for inorganic transparent photovoltaics," the research's lead ...
