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.

“…Different blends have been investigated, and optimization steps have been performed to boost the PCE of the proposed solar cells [39][40][41][42][43]. In addition, many research simulation studies related to CIGS can also be found concerning the impact of defect states, bandgap grading, ultra-thin film absorber, and many other effects, whether for a single-junction CIGS or when incorporating CIGS as a bottom subcell in a TSC [44][45][46][47][48][49]. Regarding all previous analyses, studies on the integration of all-polymer/CIGS TSC by simulation are not present in the literature.…”

Tandem solar cells (TSCs) have attracted prodigious attention for their high efficiency, which can surmount the Shockley–Queisser limit for single-junction solar cells. Flexible TSCs are lightweight and cost-effective, and are considered a promising approach for a wide range of applications. In this paper, a numerical model, based on TCAD simulation, is presented to assess the performance of a novel two-terminal (2T) all-polymer/CIGS TSC. To confirm the model, the obtained simulation results were compared with standalone fabricated all-polymer and CIGS single solar cells. Common properties of the polymer and CIGS complementary candidates are their non-toxicity and flexibility. The initial top all-polymer solar cell had a photoactive blend layer (PM7:PIDT), the optical bandgap of which was 1.76 eV, and the initial bottom cell had a photoactive CIGS layer, with a bandgap of 1.15 eV. The simulation was then carried out on the initially connected cells, revealing a power conversion efficiency (PCE) of 16.77%. Next, some optimization techniques were applied to enhance the tandem performance. Upon treating the band alignment, the PCE became 18.57%, while the optimization of polymer and CIGS thicknesses showed the best performance, reflected by a PCE of 22.73%. Moreover, it was found that the condition of current matching did not necessarily meet the maximum PCE condition, signifying the essential role of full optoelectronic simulations. All TCAD simulations were performed via an Atlas device simulator, where the light illumination was AM1.5G. The current study can offer design strategies and effective suggestions for flexible thin-film TSCs for potential applications in wearable electronics.
