Simulation on stack-layer passivation antireflection structure of metallurgical grade silicon solar cells
摘要
Abstract
PC1D simulation software was used to simulate SiO2/SiNx/SiNx stack-layer passivation antireflection structure of p-type metallurgical grade silicon solar cells. The simulation results show that it can significantly improve external quantum efficiency and surface antireflection of the cell when a SiO2 passivation layer is introduced in the SiNx/SiNx double-layer antireflection structure, and ultimately improve the cell conversion efficiency. With the increasing of SiO2 film thickness, the surface reflectance of the cell increases at first and then decreases, while the external quantum efficiency and conversion efficiency of the cell show an opposite trend. There is little change on the efficiency of the cell when the thickness of SiO2 passivation film ranges from 2 nm to 8 nm, while the cell’s efficiency significantly decreases when the thickness of silicon dioxide layer is greater than 8 nm. Maximum efficiency (18.04%) appears when the thickness of silicon dioxide layer in the SiO2/SiNx/SiNx stack-layer passivation antireflection structure is 6 nm.关键词
