Performance Evaluation of Ag/WO3/CuO/Si Heterojunction Solar Cell: The Effect of Window Layer Thickness
This research study focused on providing a solution to the problem of efficiency in the solar cell using window layer thickness. A novel Ag/WO3/CuO/Si heterojunction solar cell geometry as a function of WO3 window layer thickness via cost-effective hydrothermal and spin coating approaches has been demonstrated. The structural, morphological, and optical characteristics were systematically studied, indicating a direct correlation with the fabricated solace cells’ efficiency. In detail, a decrease in the WO3 layer thickness from 150 to 50 nm resulted in the average transmission increment from 58 to 75%; this, in turn, allowed higher power conversion efficiency enhancement from 0.063 to 1.387%. Specifically, short circuit currents of 0.307 and 6.206 mA/cm2 and open circuit voltages of 0.259 and 0.779 V were attained for the aforementioned layers’ thickness, respectively.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
