Cu2ZnSnS4 (CZTS) is an important material in low-cost thin film solar cells and is also a promising candidate for lithium storage. In this work, a novel three-dimensional CZTS film coated with a lithium phosphorus oxynitride (LiPON) film is fabricated for the first time and is applied to thin-film lithium-ion batteries. The modified film exhibits an excellent performance of ∼900 mAh g(-1) (450 μAh cm(-2) μm(-1)), even after 75 cycles. Morphology integrity is still maintained after repeated lithiation/delithiation, and the main reaction mechanism is analyzed in detail. The significant findings from this study indicate the striking advantages of modifying both the surface and structure of alloy-based electrodes for energy storage.

“…Besides, Sn species also have some reactions in this potential region [20][21][22]. The appearance of the strongest oxidation peak located at 1.2 V is most probably due to the decomposition of Cu and Sn species [23,24] Three irreversible oxidation peaks located at 0.1 V, 1.3 V and 1.4 V were observed for CZTSe nanocrystals. Similar three oxidation peaks were also observed for CZTSe 4Àx S x nanocrystals (0.3 V, 1.1 V and 1.5 V).…”

The Cu 2 ZnSnS 4 (CZTS) powders are successfully synthesized by using ZnS and Cu 2 SnS 3 as raw materials directly without any intermediate phase at 450 °C for 3 h in Ar atmosphere. The crystalline structure, morphology and optical properties of the CZTS powders are characterized by X-ray diffraction (XRD), Raman spectrum, field emission scanning electron microscopy (FESEM) and ultraviolet-visible (UV-vis) spectrophotometer, respectively. The results show that the band gap of the obtained CZTS is 1.53 eV. The CZTS film is fabricated by spin coating a mixture of CZTS powders and novolac resin with a weight percentage of 30%. The photoelectrical properties of such CZTS films are measured, and the results show an incident light density of 100 mW·cm -2 with the bias voltage of 0.40 V, and the photocurrent density can approach 9.80×10 -5 A·cm 2 within 50 s, giving an on/off switching ratio of 1.64.Chalcopyrite semiconductor compounds, such as Cu(In,Ga)Se 2 (CIGS), are the promising absorber materials for thin film solar cell with demonstrated power conversion efficiency (PCE) of 20.8% [1,2] . However, CIGS requires rare scattering elements of In and Ga, which could limit the low-cost and large-scale application of CIGS. Therefore, seeking and synthesizing an abundant and environmental absorber material candidate with suitable photovoltaic properties has been becoming urgent. The quaternary Cu 2 ZnSnS 4 (CZTS) has received remarkable attention as a promising candidate for absorber materials due to its abundance, low toxicity, and suitable optical and electrical properties [3][4][5] . CZTS is a p-type semiconductor with a band gap of 1.45-1.6 eV which approaches the optimum value for solar photoelectric conversion [6] . CZTS has been fabricated by various methods, including solvothermal method [7,8] , hot injection method [9,10] , microwave-assisted solution method [11,12] , and so on [13][14][15] . Among these methods, the use of organic solvent is the common shortcoming. Considering environmental and energy conservation issues, a more environmental method with a low annealing temperature is constantly being pursued. Wen Li et al [16] reported a two-step hydrothermal method to synthesize Cu 2 SnS 3 @ZnS nanoparticles with core-shell structure. This method reduced the production cost, but the procedure was complex. In this paper, we report a low-cost, simple and environmental method for the fabrication of CZTS, and in the production process, Cu 2 SnS 3 and ZnS directly react to synthesize CZTS for 3 h at 450 °C in Ar atmosphere without using toxic materials. In addition, this method is advantageous to the large-scale application of CZTS solar cell.In a typical synthesis process of ZnS, 0.1 mol zinc (II) chloride (ZnCl 2 , 98%) and 0.1 mol sodium sulfide (Na 2 S·9H 2 O, 98%) were dissolved in deionized water, respectively, and then the Na 2 S solution was slowly dripped into ZnCl 2 solution. The resulting ZnS precipitates were centrifuged and washed several times with distilled water, and then dried at 70 °C for 6 h in v...
