“…Mora-Herrera and Pal reported a CZTS/ACZTSe tandem solar cell with a maximum efficiency of 16.2% and a high V oc of 1.37 V after optimizing the top and bottom subcells using modifications of back contact and buffer/absorber interface engineering [26]. Previous studies have documented the outstanding combination of the BSF with different materials, as the BSF is crucial in decreasing carrier recombination in the device's backside [27][28][29]. Recently, Babu et al theoretically investigated a CZTSSe-based solar cell employing Zn 3 P 2 as a BSF layer and showed that adding the BSF increased efficiency from 17.8% to 19.7% [30].…”

Copper zinc tin sulfide (CZTS) and copper zinc tin sulfo selenide (CZTSSe) kesterite minerals are nontoxic and abundant in the earth with the promise of cost-effective photovoltaic applications. This study explains a tandem solar cell made of kesterite materials that can capture sunlight over a broad spectrum. The tandem solar cell under consideration consists of a wide bandgap CZTS thin-film upper subcell and an underlying narrow bandgap CZTSSe-based lower subcell. To begin with, SCAPS-1D was employed to model the experimental CZTS- and CZTSSe-based solar cells to fit the simulated and experimental results. Additionally, adding a back surface field (BSF) layer, a modification of the back contact, testing at different thicknesses, and doping of both subcells absorber layer result in improving the open-circuit voltage (Voc) to a maximum of 1.5 V, which led to an exceptional tandem solar cell efficiency of 23.99% at current matching circumstances. Furthermore, how light radiation power and temperature variations impact the proposed solar cell performance is being investigated. This study provides significant insights into the efficient tandem solar cell design and manufacture.

Switching from conventional to renewable solar energy has colossal cost-parity challenges. [1] Cost parity in favor of photovoltaics (PV) could be made by maximizing wattage to cost ratio (W/$) [2] for solar cells. High W/$ matric could be achieved by using affordable material, fabrication process, mass scale production, and highefficiency device configuration with better wattage output. In the current PV research landscape, the primary aim of all the research efforts is to maximize output efficiency or lower the overall input cost. Nonsilicon alternatives such as Cu 2 ZnSnS 4 , Sb 2 Se 3, and FeS 2 offer exciting cost reductions owing to low material utilization in thin films, lower cost, and faster throughput fabrication process due to state-of-the-art nanotechnology. [3] Additionally, thin-film sulfide/selenide materials, such as Cu 2 ZnSnS 4 (CZTS) and Sb 2 S 3, are potentially cost-effective owing to the earth-abundant constituent elements. [4][5][6][7][8][9] Realizing high efficiency in low-cost systems is critical to substantiate PV as a future energy source. PV must simultaneously outperform on both the technological and economic fronts. Newer low-cost materials with high-efficiency yielding configuration and device design are required for achieving high W/$ matric. The practical approach to competitive PV narrowed down to two-variable between input cost (material and fabrication) of thin-film solar cells and a high-efficiency technique.In this line, cost-effective chalcogenide material (sulfides, selenides) with a high-efficiency configuration, such as a dualabsorber device design [10][11][12][13][14][15][16][17][18][19][20] for high-efficiency is pursued in this study. The double-absorber technique utilizes two distinct bandgap absorbers to cover a broader spectrum reducing spectrum losses (thermalization and non-absorption). We have taken CZTS and Sb 2 Se 3 absorber pairs for double absorbers as they are earth-abundant, nontoxic, potentially low-cost alternative absorber materials for PV. [21] Among all upcoming cost-effective PV materials (like CZTS, Sb 2 S 3 , SnS, FeS 2 , etc.), CZTS and Sb 2 Se 3 are the only material which has shown practical efficiency beyond the 10% mark. [22] These have excellent absorption properties and optimal bandgap with wide tunability. [23,24] The substitution of selenium in place of sulfur could tune their bandgap in Cu 2 ZnSn(S x Se 1Àx ) 4 (CZTSSe) [25] and Sb 2 S x Se 3Àx . [26] Solution-processable, high-throughput, and energy-efficient

“…It is clearly shown that the tandem solar cell exhibits a short-circuit current of 15.2 mA cm −2 , FF of 68.6%, and PCE of 20.1%.

Perovskite-based tandem solar cells emerged as potential candidates for efficient photovoltaic applications. These devices exhibit high optical absorption properties and tunable direct band-gap. In this work, a novel lead-free Perovskite-SnS Tandem solar cell based on alternative charge transport layers combined with plasmonic-based light management approach is proposed. Accurate numerical investigation is carried out to assess the influence of the charge transport layers of top sub-cell on the optoelectronic properties of the tandem cell. The obtained results reveal the potential of SnO2 and CuO materials as electron and hole transport layers, respectively, demonstrating a good conduction band offset (CBO) and thereby enhanced recombination losses. Furthermore, the role of Gold-nanoparticles in enhancing absorption and light-trapping mechanisms in the bottom SnS-based sub-cell is investigated using FDTD computations. It is found that the optimized tandem cell with Au-NPs exhibits a high power conversion efficiency of 20.1%. Therefore, this work can open up new paths to boost the power conversion of Sn-based Perovskite/SnS Tandem cells for high-performance and eco-friendly photovoltaic applications.
