Design of Silicon Nano-Bars Anti-Reflection Coating to Enhance Thin Film Solar Cells Efficiency
In this paper a novel anti-reflection (AR) coating based on silicon nano-bars is designed and its impact on the performance of crystalline silicon (c-Si) thin-film solar cells is extensively studied. Silicon nano-bars with optimized size and period are embedded on top of the active layer, under a 100nm Si3N4 layer. As a result of the proposed layer stack, an inhomogeneous intermediate layer wit...
متن کاملImproving the optical properties of thin film plasmonic solar cells of InP absorber layer using nanowires
In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...
متن کاملANTI-REFLECTION LAYER AT THE TCO/Si INTERFACE FOR HIGH EFFICIENCY THIN-FILM SOLAR CELLS DEPOSITED ON ROUGH LP-CVD FRONT ZnO
ZnO layers with a wide range of surface roughness and morphologies can be deposited by low pressure chemical vapor deposition (LP-CVD). In this paper, we investigate the effect of a low-resistivity TiO2-ZnO bi-layer incorporated as an anti-reflection coating between the rough ZnO front transparent conductive oxide (TCO) and the silicon layer, for thin film p-i-n microcrystalline silicon solar c...
متن کاملRole of SiNx Barrier Layer on the Performances of Polyimide Ga2O3-doped ZnO p-i-n Hydrogenated Amorphous Silicon Thin Film Solar Cells
In this study, silicon nitride (SiNx) thin films were deposited on polyimide (PI) substrates as barrier layers by a plasma enhanced chemical vapor deposition (PECVD) system. The gallium-doped zinc oxide (GZO) thin films were deposited on PI and SiNx/PI substrates at room temperature (RT), 100 and 200 °C by radio frequency (RF) magnetron sputtering. The thicknesses of the GZO and SiNx thin films...
متن کاملNew progress in the fabrication of n–i–p micromorph solar cells for opaque substrates
In this paper, we investigate tandem amorphous/microcrystalline silicon solar cells with asymmetric intermediate reflectors grown in the n–i–p substrate configuration. We compare different types of substrates with respect to their light-trapping properties as well as their influence on the growth of single-junction microcrystalline cells. Our most promising back reflector combines a textured zi...
