Synthesis and Photoelectric Properties of Cu2ZnGeS4 and Cu2ZnGeSe4 Single-Crystalline Nanowire Arrays

Cu2ZnGeS4 (CZGS) and Cu2ZnGeSe4 (CZGSe) single crystalline nanowire arrays have been prepared via a convenient one-step nanoconfined solvothermal approach. The porous anodic aluminum oxide was used as a morphology directing template by offering nanospace in the AAO pores for confined solvothermal reaction. The structure, morphology, composition, and optical absorption properties of the as-prepared samples were characterized using X-ray powder diffraction, transmission electron microscopy, energy dispersive X-ray spectrometry, scanning electron microscopy, and a UV–vis spectrophotometer. The CZGS and CZGSe films are found to have obvious photoelectric response, indicating their potential in the application of photovoltaic devices.
