High-Efficiency Polycrystalline CdTe Thin-Film Solar Cells with an Oxygenated Amorphous CdS (a-CdS:O) Window Layer: Preprint
In the conventional CdS/CdTe device structure, the poly-CdS window layer has a bandgap of ~2.4 eV, which causes absorption in the short-wavelength region. Higher short-circuit current densities (Jsc) can be achieved by reducing the CdS thickness, but this can adversely impact device open-circuit voltage (Voc) and fill factor (FF). Also, poly-CdS film has about 10% lattice mismatch related to th...
متن کاملInfluence of Window and Absorber Layer Processing on Device Operation in Superstrate Thin Film Cdte Solar Cells
Processing strategies are presented for controlling junction quality as both window and absorber layer thickness are reduced in polycrystalline superstrate CdS/CdTe thin-film solar cells. High resistance In2O3 and SnO2 oxide buffer layers improve coverage of chemical bath deposited CdS and device performance with PVD CdTe, resulting in efficiencies >13.5%. A new method of CdS and Cd1-xZnxS chem...
متن کاملSULFUR DIFFUSION IN POLYCRYSTALLINE THIN-FILM CdTe SOLAR CELLS
X-ray diffraction and photoluminescence measurements have been used to characterize the diffusion of S into CdTe during post growth annealing of CdTe solar cells. For anneals at 410°C in the presence of CdCl2, evidence that both a CdTe1-xSx phase and nearly-pure CdTe are present near the back contact is observed. The ternary phase becomes more prominent and the S concentration increases with de...
متن کاملGrain boundaries in CdTe thin film solar cells: a review
The current state of knowledge on the impact of grain boundaries in CdTe solar cells is reviewed with emphasis being placed on working cell structures. The role of the chemical composition of grain boundaries as well as growth processes are discussed, along with characterisation techniques such as electron beam induced current and cathodoluminescence, which are capable of extracting information...
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...
