Optimization of nanostructured perovskite solar cells: Enhancing light absorption and electrical efficiency with novel designs

This study investigates the optimization of nanostructured perovskite solar cells by integrating innovative materials and geometric configurations to enhance light absorption and electrical performance. Using materials like MoSe2, CsPbI3, and CuSCN, the optical and electrical properties of the solar cells were carefully simulated with COMSOL Multiphysics software. We explore the impact of layer thicknesses and V-shaped designs on device performance, targeting maximized current density and overall efficiency. The optical constants, including the refractive index (n) and extinction coefficient (k), were extracted for the materials and implemented in simulations to model light propagation, absorption, and generation. Results show that the optimal angle of 40° significantly enhances light absorption and charge generation, leading to a superior current density of 22.3 mA/cm2. Additionally, MoSe2 was selected for its excellent absorption capability in the longer wavelengths, addressing the spectral limitations of other layers and further improving the cell's efficiency. This work provides valuable insights into the potential of nanostructured designs for high-performance solar energy devices.
