“…As shown in Figure 9c, the peaks of Sn 3d5/2 and Sn 3d3/2 were observed at 486.2 and 494.6 eV, with a peak splitting of 8.4 eV, confirming the configuration of Sn (IV). The S 2p core-level spectrum in Figure 9d gives two peaks located at 161.7 and 162.7 eV, which coincided with the 160-164 eV range of S in the sulfide phases [43]. All the above analyses suggest that when the duration time was 20 min, the structural, morphological and optical properties of as-prepared thin film were more advantageous for the application as an absorption layer in photovoltaic devices.…”

In the current study, Cu 2 ZnSnS 4 (CZTS) thin film was successfully fabricated by the facile nanocrystals (NCs)-printing approach combined with rapid thermal annealing (RTA) process. Firstly, the CZTS NCs were synthesized by a thermal solution method and the possible formation mechanism was analyzed briefly. Then the influences of RTA toleration temperature and duration time on the various properties of as-printed thin films were examined via XRD, Raman, FE-SEM, UV-vis-IR spectroscopy, EDS and XPS treatments in detail. As observed, the RTA factors of temperature and time had significant impacts on the structure and morphology of as-prepared thin films, while there were no obvious effects on the band gap energy in studied conditions. The results showed that the obtained thin film at optimal RTA conditions of (600 • C, 20 min) featured a kesterite structure in pure phase and an irregular morphology consisting of large grains. Moreover, the satisfactory composition of a Cu-poor, Zn-rich state and an ideal band gap energy of 1.4 eV suggests that as-fabricated CZTS thin film is a suitable light-absorbing layer candidate for the application in thin film solar cells.

“…Non‐vacuum processes such as spin‐coating or doctor balding offer abundant merits over vacuum processes in CIGS thin‐film solar cell production, such as low cost and easy mass production . However, the flaws, such as cracks, porous structure, small grains that easily occur in the non‐vacuum process have been the major obstacle to practical application of this technology …”

The difficulty in densification easily occur in CIGS thin film absorber fabrication using the non‐vacuum process. A novel process is developed in this study to achieve dense, crack‐free and large‐grained CIGS films by blending submicron‐sized particles with nanoparticle suspensions. The addition of slow‐sintering submicron‐sized particles to the nanoparticle suspensions effectively inhibits crack generation and small grain development in the film microstructure. The submicron‐sized particles addition to nanoparticle suspension effect on the microstructure and electrical properties are investigated using scanning electron microscopy, X‐ray diffraction, UV‐Vis‐NIR, Raman spectroscopy and Hall‐effect analyzer. A homogeneous dense microstructure with a large grain size and good electric properties can be obtained as the submicron‐sized particles ratio to nanoparticles approaches 3:7.
