“… 17 In a more recent effort, we proposed a triple junction environmental friendly CBTSSe/CZTS/ACZTSe tandem solar cell and optimized the device structure to achieve a maximum efficiency of 36.04%. 18 However, the tandem cell may suffer from practical limitations such as complexities in fabricating the tunneling junction, tunneling junction losses, high material usage and thus relatively higher fabrication cost. Thereby, despite noteworthy works have been done in recent years to increase the PCE of CZTS solar cells, further improvements are required to make them commercially viable alternatives.…”

Thin film solar cells show great potential applications in building‐integrated photovoltaics (BIPV) and portable devices. Among these thin film solar cells, Cu2BaSn(SxSe1–x)4 solar cells derived from Cu2ZnSn(SxSe1–x)4 solar cells have attracted intense research interests recently because of their high theoretical PCE of ap;31%, easy tunability of band gaps (Eg = 1.28–1.79 eV), large optical absorption coefficient (α > 104 cm−1), environment‐friendly composition, low materials, and fabrication cost. Importantly, Cu2BaSn(SxSe1–x)4 solar cells are expected to have low open‐circuit voltage deficit, leading to high open‐circuit voltage and PCEs. In fact, since their initial development in 2016, the maximum PCE of Cu2BaSn(SxSe1–x)4 solar cells has surpassed 5% via adjustment of the fabrication methods and material properties, optimization of the device structures, and so forth. Here, a review of the recent progress of Cu2BaSn(SxSe1–x)4 solar cells is presented, including properties of Cu2BaSn(SxSe1–x)4, material and device fabrication methods, device performances, potential applications, as well as the bulk and interface recombination. In addition, other solar cells which are similar with the Cu2BaSn(SxSe1–x)4 solar cells are also discussed. Finally, according to these discussions, prospect for PCEs improvement is given to accelerate their development.

The parameters are carefully chosen based on the existing theoretical and experimental measurements 20,37,40,51,55,61,65‐71 . At room temperature, the thermal velocity of both electron and hole is anticipated to be 10 7 cm/s 72‐74 .…”

This study reports on performance enhancement of a Cu2ZnSnS4 solar cell introducing Sb2S3 as hole transport layer (HTL) along WS2 as buffer layer. We have investigated photovoltaic (PV) characteristics by utilizing SCAPS‐1D. A comparative analysis on PV performances between conventional CZTS/CdS and proposed Ni/Sb2S3/CZTS/WS2/FTO/Al solar cells is presented. It is revealed that “spike like” band structure at the CZTS/WS2 interface having smaller conduction band offset makes it potential alternative to commonly used CdS buffer. This report also evaluates that the Sb2S3 as an HTL inserted at the rear of CZTS enhances performances by reducing carrier recombination at back interface with appropriate band alignment. The impacts of thickness, carrier concentration of different layers, and bulk defect density in CZTS as well as the interface defects on cell outputs are analyzed. The influences of temperature, work function, and cell resistances are also examined. Optimum absorber thickness of 1.0 μm along doping density of 1017 cm−3 is selected. A maximum efficiency of 30.63% is achieved for the optimized CZTS cell. Therefore, these results suggest that Sb2S3 as HTL and WS2 as buffer layer can be employed effectively to develop highly efficient and low‐cost CZTS solar cells.
