Abstract
Optical properties of ZnTe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1-x</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> (ZnTeO) and evidence for the photovoltaic (PV) activity of a ZnTeO intermediate band solar cell (IBSC) are reported. Electron transitions from the intermediate band to the conduction band were observed by photomodulated reflectance measurements. The optical absorption coefficients for the electron transition from the valence band to the intermediate band exceeds 2 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> , suitable for thin film PV device applications. The ZnTeO IBSC exhibits an enhanced spectral response below the bandedge of ZnTe, and all results are consistent with the proposed conversion mechanism of IBSC.
