Self-sacrificial template directed hydrothermal route to kesterite-Cu2ZnSnS4 microspheres and study of their photo response properties

Fabrication of Cu2SnS3 thin film solar cells using pulsed laser deposition technique

“…2 shows the Raman spectra of CTS:300 and CTS:400 samples in a range of 150-600 cm À 1 . The Raman spectrum for the sample CTS:300 exhibits peaks at 293 and 349 cm À 1 , which is consistent with previously reported values [20,21]. However, the presence of a Raman peak at 335 cm À 1 for the sample CTS:300 suggests the presence of orthorhombic CTS [19].…”

Non-vacuum mechanochemical route to the synthesis of Cu2SnS3 nano-ink for solar cell applications

“…2ac shows the Raman spectra of the CTS:12, CTS:36 and CTS:60 samples, respectively, in the range of 250-500 cm À1 . The existence of Cu 2 SnS 3 is confirmed by the intense peaks at $355 cm À1 and shoulder peak at 295-303 cm À1 , for all samples which are close to the values reported for CTS thin films [17,18]. The Raman spectrum of the CTS:24 sample is shown in Fig.…”

Effect of ZnS nanowire ARC on CZTS/CdS thin film solar cell by Nebulizer Spray Pyrolysis Technique

“…The optical bandgap deduced by extrapolating the light portion of the (αhv) 2 versus ( ) n h plot to meet the hv axis shown in the figure 5. The optical bandgap values of the films was found to be 1.57 eV, 2.43 eV and 3.4 eV of CZTS, CdS and ZnS respectively which is good approving with previously revealed value in literature thin films by nebulizer spray [34,35]. The optical band gap of CZTS found to be ∼1.77 eV value for a direct band gap material is quite close to the optimum value band gap for ideal for solar cell applications absorber layer of photovoltaic energy devices.…”
