Design and Analysis of High Efficiency Perovskite Solar Cells with Light Trapping Nano-textured Substrates

Recently, the utilization of hybrid organic-inorganic perovskite solar cells under advanced light management designs have attracted intensive attention.  In this study, a three-dimensional (3D) finite element method (FEM) technique was used in COMSOL Multiphysics simulation package to investigate coupled optical and electrical characteristics (PSCs) with trapping nanostructures. Upon use nano-textured fluorine-doped tin oxide (FTO) substrates, we propose two architectures which can guide trap at nanometer dimensions. Two proposed PSCs i.e. concave trapezoidal structures are compared planar structure order effects using nanostructured substrates on optoelectronic performance PSCs. Optical analysis reveals that optimized enhance absorption up 32 26%, respectively wavelength 550 nm. Electrical simulations shown addition enhanced total carrier generation, generated carriers be effectively collected Accordingly, short-circuit current has risen from 20 mA for 25.7 23.2 After analyzing various heights adopting optimum values, power conversion efficiency experienced substantial increase 5.5 3.5%, structure. These drastic improvements analyzed by modelling nanostructures pave way further studies fabricate high as light-trapping technique.
