In Situ Dynamic Construction of a Copper Tin Sulfide Catalyst for High-Performance Electrochemical CO2 Conversion to Formate

“…The X-ray photoelectron spectroscopy (XPS) survey spectra clearly reveal the presence of Sn, Cu, and S elements in the precatalyst (Figure S1 and Table S1, Supporting Information). The high-resolution XPS spectra of Sn 3d for the precatalyst show two characteristic peaks at the binding energy of 495.7 and 487.3 eV with a separation of 8.4 eV (Figure g), which can be assigned to Sn 3d 3/2 and Sn 3d 5/2 , respectively, − suggesting the Sn 4+ state in the precatalyst. The Cu 2p spectrum exhibits four obvious peaks of Cu 2p 1/2 (951.7, 952.5 eV) and Cu 2p 3/2 (931.8, 932.6 eV) with a separation of 19.9 eV, indicating the +2 and +1 oxidation states of Cu species for Cu 2 SnS 3 and CuS in the precatalyst, respectively (Figure h). ,− The high-resolution S 2p spectrum can be deconvoluted into two components, corresponding to S 2p 1/2 (163.1 eV) and S 2p 3/2 (161.7 eV) (Figure i). ,, Additionally, the elemental ratio of the precatalyst was also investigated by ICP-MS characterization, in which the atomic ratios of Cu/Sn and S/Sn are close to 2 and 3, respectively.…”

The Investigation of Photovoltaic and Electrical Properties of Bi Doped CTS/Si Hetero-Junction Structure for the Solar Cell Application

“…In Eq (10), 𝛾 is the first constant higher than ideality factor which was determined by logarithmic J-V curve. Ф 𝑏 and 𝑅 𝑠 values can be calculated by Eq (11) and Eq (12) in Norde method; (11) and Eq (12) to be 49.63Ω, 0.65 eV and 43.63Ω, 0.70 eV in the darkness and under the illumination conditions, respectively.…”

“…Furthermore, these parameters have been improved the open circuit voltage (Voc), filling factor (FF) and power conversion efficiency (η) of produced solar cells [9]. With this point of view, Antimony (Sb) element, which shares the same group element with Bi atom, has developed the crystal structure of Cu2SnS3 [10] showing that Bi doping element can increase the efficiency of Cu2SnS3 based solar cell to be produced.…”

Effect of Sulfur Precursors on Crystallographic, Optical, and Electrical Properties of Cu2SnS3 Nanoparticles

“…CTS is a ternary semiconductor material belongs to group I-IV-VI series that has similar optoelectronic properties to CZTS and high potential for photovoltaic applications. CTS is characterized by p-type conductivity with high absorption coe cient (>10 4 cm -1 ) as well as excellent bandgap (0.9 -1.77 eV) but consists of less elements than CZTS [1][2][3][4][5].…”
