MULTIBAND SEMICONDUCTOR COMPOSITIONS FOR PHOTOVOLTAIC DEVICES |
| 摘要 |
The highly mismatched alloy Znl-yMnyOxTe1-x- 0<=y<l and O<x<1 and other Group II-IV-Oxygen implanted alloys have been synthesized using the combination of oxygen ion implantation and pulsed laser melting. Incorporation of small quantities of isovalent oxygen leads to the formation of a narrow, oxygen-derived band of extended states located within the band gap of the Znl-yMnyTe host. With multiple band gaps that fall within the solar energy spectrum, Znl-yMnyOxTel1-x is a material perfectly satisfying the conditions for single junction photovoltaics with the potential for power conversion efficiencies surpassing 50%. |
