研究目的
To simulate different structures of Perovskite nanorod solar cells (PNSCs) and optimize their parameters for maximum conversion efficiency.
研究成果
The numerical study of PNSC using FEM software shows that the TiO2 cylindrical rod achieves the maximum conversion efficiency of about 18.67%, suggesting that the rod structure is more suitable for solar energy harvesting.
研究不足
The study is limited to numerical simulation and does not include experimental validation of the fabricated cells. The optimization is based on specific parameters (rod length, radius, and spacing) and may not account for all possible variables affecting cell performance.
1：Experimental Design and Method Selection:
The simulation is based on the finite element method (FEM) using COMSOL Multiphysics software. The study models four different PNSC structures: cylindrical rod, cone rod, inverted-cone rod, and modulated rod.
2：Sample Selection and Data Sources:
The material of the modeled cell is TiO2/CH3NH3PbI
3：The study uses AM5G standard illumination of ASTM G-173 global tilt solar spectrum. List of Experimental Equipment and Materials:
COMSOL Multiphysics software for simulation.
4：Experimental Procedures and Operational Workflow:
The study involves optimizing rod length, radius, and spacing between rods for all structures to achieve the maximum conversion efficiency.
5：Data Analysis Methods:
The conversion efficiency is defined as the ratio of the maximum power point to the input power, estimated from the illumination AM1.5G spectrum.
