摘要

This work improved energy efficiency, stability and energy stability in organic and organic perovskite solar cells, by using titanium dioxide as anti-reflective coating on silver. The use of graphene oxide-nickel oxide layer as a hole-transporting layer enhanced carrier mobility in addition to incrementing stability. The outcomes that have been meticulously extracted and analyzed from the finite-difference time-domain (FDTD) simulations provide compelling evidence that this particular methodology can be adeptly utilized to significantly enhance the capability to attain a remarkably broad absorption spectrum across a wide range of wavelengths, specifically those identified frorm 200 nm to 900 nm, which are of critical importance in solar cell applications. Optical analysis was conducted by Maxwell method. Dielectric plasmonic wire grating was proposed to increase optical absorbance and achieve maximum current. The electrical analysis of the structure was based on Poisson’s equations. Optical analysis of the inorganic halide perovskite revealed current density, open circuit voltage, fill factor, and power of 34.294 mA/cm2, 1.04 V, 0.83369817, and 1.64 mA/cm2. The energy conversion efficiency was also 29.3%.
