Since the crystal quality issues have been improved significantly, a further numerical optimization in the structure design is needed. We applied FDTD program for optical absorption and use our Poisson and drift-diffusion solver for electrical simulation. The Poisson and drift-diffusion solver is optimized for sovling organic and inorganic materials. Finally, we design a nano-structure that have efficiency of MAPBI 3 based solar cell has been improved from 18% to 19.67% That efficiency has be enhanced by 12% compared to the planar structure. ? 2018 IEEE.Crystal structure; Diffusion; Efficiency; Light absorption; Nanostructured materials; Nanostructures; Numerical models; Optoelectronic devices; Perovskite; Perovskite solar cells; Structural optimization; Drift diffusion; Efficiency increase; Electrical simulation; High-efficiency solar cells; Inorganic materials; MAPBI3; Numerical optimizations; Organic; Solar cellsconference paper10.1109/NUSOD.2018.85702922-s2.0-85060043664
