“…As expressed in the spectrum sketched in Fig. 5, CTS thin film has an absorption coefficient greater than 5.5×10 4 cm -1 in the visible region and this result is compatible with Cu2SnS3 absorption coefficients reported in the literature [1]. It has been observed that the absorption coefficient decreases towards to near-infrared region.…”

“…However, in recent years, since CZTS consists of many elements and its second phases are easily formed, research studies have been carried out on Cu2SnS3 (CTS) material for use in PV field. CTS is a p-type semiconductor with band gap values ranging from 0.9 to 1.7 eV and a high absorption coefficient (>10 4 cm -1 ) [1]. Due to different arrangements of atoms in a lattice structure of CTS, different phases such as Cu4Sn7S16, Cu4SnS4, Cu3SnS4 structure can also occur [2].…”

Cu2SnS3 (CTS) thin film has been produced for 30 ccm sulphur flux rate at 30 minutes annealing durations at 550 oC temperature. CTS thin film’s crystalline structure has been investigated and crystalline size, lattice parameters, dislocation density and microstrain, crystalline number have also been determined. The CTS thin film’s morphological and optical properties have been examined and thoroughly interpreted. Mo/CTS/CdS/AZO solar cell has been modelled based on CTS thin film produced at the present work, using SCAPS-1D simulation programme. Voc, Jsc, FF, conversion efficiency and photovoltaic parameters have been determined depending on neutral defect density at the interface, coefficient of radiative recombination, Auger electron/hole capture’s coefficient and operation temperature of CTS solar cell. As a consequence of simulation study, ideal efficiency of CTS solar cell has been determined to be 3.72 % and all the data obtained in this study have been presented, interpreted and concluded to be original results.

The study of photovoltaic solar cells has been an exciting field of research because of their environmentally friendly nature. Scientists are continuously searching for new methods to develop solar cells that are highly efficient and cost-effective. One promising option is the use of Copper Antimony Sulphide (CuSbS2) based ternary compound semiconductor in ultrathin film photovoltaic cells. This material has a high absorption coefficient, low cost, and is readily available in the earth's crust. These characteristics make it an ideal candidate for use as a thin-film absorber layer in solar cells. In this work, FTO/CdS/In2S3/CuSbS2/Spiro-OMeTAD/Au device is proposed to improve the efficiency of experimentally designed CuSbS2-based thin film solar cells using numerical modeling. Device simulation was carried out using SCAPS-1D software, and the illumination spectrum used for this optimization was 1.5 AM. The simulated results from SCAPS-1D were compared to the experimental data. After optimizing the device parameters all the electrical parameters of the solar cell were improved. The optimized CuSbS2-based device shows power conversion efficiency (PCE) of 21.11% with short circuit current density (Jsc) of 20.96 mA/cm2, open circuit voltage (Voc) of 1.23 V, and fill factor (FF) of 81.84 %. Based on the simulation results, it is possible to increase the performance of the device by varying different parameters such as the defect density of each layer, interfacial defect density, thickness, and doping concentration.
