“…It was worthy of note that a low‐intensity band at 327 cm −1 corresponding S anion was only observed in the Raman spectra of the sample A2. This band was attributed to A1 mode symmetric vibrations of the CZTSSe phase 41‐43 . The presence of this low‐intensity band at 327 cm −1 in the Raman spectra of the sample A2 could be also considered as another indication of a very low amount of S content in the sample A2 44 …”

Summary Cu2ZnSnSe4 and Cu2ZnSn(S,Se)4 absorber films were grown on soda lime glass and Mo‐coated soda lime glass substrates by deposition of the precursor films via RF magnetron sputtering method in the stacking orders of Cu/Sn/Zn/Mo/SLG and Cu/Sn/ZnS/Mo/SLG using metallic Zn or binary sulfide ZnS targets and subsequently carrying out of selenization process. It was aimed to find out the effect of Zn or ZnS target types and the small amount of S originated from ZnS target material used in the deposition of precursor films on the structural, morphological, optical, and electrical characteristics of the films to be selenized. XRD and Raman spectroscopy analysis showed that the kesterite CZTSe structure was predominantly formed in both cases where Zn and ZnS targets were used. According to the EDX analysis, S content in the prepared film using ZnS target was only around 1.79 at%. This indicated that a considerable amount of S in the film was driven out during the selenization process. Scanning electron microscopy analysis revealed that ZnS target material contributed to the achievement of the absorber films with larger grain size. It was also determined that the thickness of the interfacial MoSe2 film between the absorber and Mo films decreased by using ZnS target in the precursor film. This was attributed to ZnS layer with a high melting point acting as a barrier layer over Mo film and retarding the diffusion of Se into the Mo film during the selenization process. In addition, the band gap energy values of the Cu2ZnSnSe4 and Cu2ZnSn(S,Se)4 films were found to be 1.18 and 1.28 eV, respectively.

“…Origin of (PSC) starts from the device structure of DSSCs [11]. Two of the important properties of perovskite is its largely tunable bandgap ( i.e; PSC has a band-gap from 1.5 to 2.3 eV) [19]& high light captivation co-efficient which is larger than 10 4 cm -1 [20,21] that is comparable to other thin film PV constituent ingredientsi.e; materials of CZTS and CdTe [22,23]. Its suitable and low-cost fabrication techniques also play an important role as compared to Si-based fabrication that is costly and complex high vacuum deposition method.…”

The Thin film technology is one of the fastest growing technologies because of the increase in energy demands and scarcity of energy materials. In thin film solar PVs PSC & CZTS are two of the most promising, abundant and efficient thin film solar PVs. They offer tunable band-gaps that can be adjusted for maximum PCE. Perovskite is one of the efficient solar PV material with a band-gap ranges between 1.55 to 2.3 eV which is too much close to the optimum photovoltaic conversion material. But it is less stable and vulnerable to environment while CZTS is more stable but have less band-gap as compared to perovskite. So, we make a tandem of perovskite & CZTS to utilize their efficiencies and durability. We simulate different thickness of layers and band-gaps of this tandem using SCAPS-1D, which is one of the best utilities for efficiency calculations of thin film solar PVs. We performed different simulations for that tandem while changing the allowable thickness of absorber layers & their band-gaps to obtain an optimum solution. During multiple simulations I obtained a better efficiency of 22.61% which was the greater efficiency during my simulations.I have used SCAPS-1D for modeling and simulations of thin film Perovskite and CZTS solar cells, calculated their I-V curve QE (quantum efficiency) for different thickness whose ranges are 200-500 nm for perovskite and 200nm to 1.2um for CZTS with step-length thickness of 25nm. I selected the best configuration for my simulations for better performance, on which I performed further simulations and chose model with efficiency of 22.61%. Which shows that a handsome amount of conversion efficiency is achievable for tandem solar cells consist of Perovskite and CZTS.

“…The structure of PSCs also origins from the device structure of DSSCs [ 1 ]. The perovskite materials have been demonstrated with largely tunable band gap (e.g., CH 3 NH 3 PbX 3 has a band gap from 1.5 eV to 2.3 eV) [ 4 ] and great light absorption coefficient (higher than 10 4 cm −1 ) [ 5 , 6 ], which is similar to other thin film solar cell materials such as CdTe [ 7 ] and copper zinc tin sulfide (CZTS) [ 8 ]. Its low-cost and convenient fabrication techniques also serve as the possible advantages over silicon-based devices that require complicated and costly high-vacuum deposition methods.…”

With the rapid increase of efficiency up to 22.1% during the past few years, hybrid organic-inorganic metal halide perovskite solar cells (PSCs) have become a research “hot spot” for many solar cell researchers. The perovskite materials show various advantages such as long carrier diffusion lengths, widely-tunable band gap with great light absorption potential. The low-cost fabrication techniques together with the high efficiency makes PSCs comparable with Si-based solar cells. But the drawbacks such as device instability, J-V hysteresis and lead toxicity reduce the further improvement and the future commercialization of PSCs. This review begins with the discussion of crystal and electronic structures of perovskite based on recent research findings. An evolution of PSCs is also analyzed with a greater detail of each component, device structures, major device fabrication methods and the performance of PSCs acquired by each method. The following part of this review is the discussion of major barriers on the pathway for the commercialization of PSCs. The effects of crystal structure, fabrication temperature, moisture, oxygen and UV towards the stability of PSCs are discussed. The stability of other components in the PSCs are also discussed. The lead toxicity and updated research progress on lead replacement are reviewed to understand the sustainability issues of PSCs. The origin of J-V hysteresis is also briefly discussed. Finally, this review provides a roadmap on the current needs and future research directions to address the main issues of PSCs.
