Processing methods for CZTS in the literature are energy-intensive, requiring the sequential sputtering of metal layers at 700 degrees C, followed by an annealing step in a sulfur-containing atmosphere at 500 degrees C. The presence of CZTS is clear in the …
WebCZTS-based devices, investigators are making efforts by varying material compositions, preparation methods, etc. [1]. An approach CZTS band grading from the element ger-manium (Ge) is also getting much attention. It has predicted that CZTS alloying with Ge can provide a suitable band grading in CZTS; therefore, overall active layer working WebOur analysis indicates that current CZTS devices might have already approached the maximum conversion efficiency (14%) given the limited growth conditions and the remnant cation disorder even after postannealing.
Webthat the wurtzite phase of CZTS was completely transformed into the kesterite phase when the material was annealed at 550 °C. Large grains (~2 μm) were detected on the surface of the CZTS thin film when the annealing temperature was carried out at 600 °C. CZTS films annealed at 600 °C exhibited higher anmore stable d WebJun 1, 2024 · In this thesis, we chose Cu2ZnSnS 4, a quaternary compound semiconductor, as a promising non-toxic, earth-abundant, and cheap candidate from emerging thin-film …
