Enhancing the near-infrared spectral response of silicon optoelectronic devices via up-conversion
A silicon-based optoelectronic device that exhibits an enhanced response to subbandgap light is described. The device structure consists of a bifacial silicon solar cell with an upconverting (UC) layer attached to the rear. Erbium-doped sodium yttrium fluoride (NaY0.8 F4: Er0.23+) phosphors are the optically active centers responsible for the UC luminescence. The unoptimized device is demonstrated to respond effectively to wavelengths (λ) in the range of 1480-1580 nm with an external quantum...[Show more]
