Title: Lifetime of excess electrons in Cu–Zn–Sn–Se powders

Abstract

The method of time-resolved microwave photoconductivity at a frequency of 36 GHz in the range of temperatures of 200–300 K is used to study the kinetics of the annihilation of charge carriers in Cu–Zn–Sn–Se powders obtained by the solid-phase method of synthesis in cells. The lifetime of excess electrons at room temperature is found to be shorter than 5 ns. The activation energy for the process of recombination amounted to E{sub a} ~ 0.054 eV.

  • Cu-deficient Cu{sub 1.75}ZnSn{sub 1−x}Al{sub x}Se{sub 4} (x=0–0.6) bulks were prepared by a liquid-phase reactive sintering method at 600 {sup °}C with soluble sintering aids of Sb{sub 2}S{sub 3} and Te. Defect chemistry was studied by measuring electrical properties of Al-doped CZTSe as a function of dopant concentration. Al-CZTSe pellets at x=0.4 with electrical conductivity of 57.2 S cm{sup −1} showed the highest hole mobility of 32.5 cm{sup 2} V{sup −1} s{sup −1}. The high mobility is mainly contributed from the low atomic scattering factor of Al. The high carrier concentration and slightly changed lattice parameter of Al-CZTSe are related tomore » the types of its defects. - Graphical abstract: The controls in electrical properties and the changes in lattice parameters of Cu-deficient Cu{sub 2}ZnSnSe{sub 4} by doping Al{sup 3+} on the Sn{sup 4+} site. Display Omitted - Highlights: • Cu-deficient Cu{sub 1.75}Zn(Sn{sub 1−x}Al{sub x})Se{sub 4} was prepared by liquid-phase sintering at 600 °C. • Sintering aids of Sb{sub 2}S{sub 3} and Te were used for reactive sintering. • Al-CZTSe at x=0.4 showed the extremely high mobility of 32.5 cm{sup 2} V{sup −1} s{sup −1}. • Al-CZTSe reached large grains of 2−3 μm, while it was <1.0 μm for the undoped. • Electrical properties of Al-CZTSe pellets changed with the Al content.« less
  • Kesterite thin films (i.e., Cu{sub 2}ZnSn(S,Se){sub 4} and related alloys) have been the subject of recent interest for use as an absorber layer for thin film photovoltaics due to their high absorption coefficient (> 10{sup 4} cm{sup -1}), their similarity to successful chalcopyrites (like CuInxGa{sub 1-x}Se{sub 2}) in structure, and their earth-abundance. The process window for growing a single-phase kesterite film is narrow. In this work, we have documented, for our 9.15%-efficient kesterite co-evaporation process, (1) how appearance of certain undesirable phases are controlled via choice of processing conditions, (2) several techniques for identification of phases in these films withmore » resolution adequate to discern changes that are important to device performance, and (3) reference measurements for those performing such phase identification. Data from x-ray diffraction, x-ray fluorescence, Raman scattering, scanning electron microscopy, energy dispersive spectroscopy, and current-voltage characterization are presented.« less
