Quadruple-layer antireflection coating for high-efficiency IMM3J solar cells by GLAD
A quasi-gradient refractive index quadruple-layer antireflection coating (QLARC) nano-MgF2/ZnS/MgF2/ZnS was designed for inverted metamorphic triple junction (IMM3J) solar cells, with optimization and simulation using the Essential Macleod. The top layer nanoporous MgF2 (nano-MgF2) film was fabricated utilizing the glancing angle deposition (GLAD) technique, achieving tailored refractive indices from 1.39 to 1.20 through controlling deposition angle (θα = 24°-89°). The photovoltaic performance of quasi-gradient QLARC was compared with that of a conventional double-layer antireflection coating (DLARC). Both DLARC and QLARC reduced the solar spectrum-weighted average reflectance (SSWAR) of IMM3J solar cells by 23.46% and 25.45%, respectively, in the wavelength range of 300–1300 nm. By reducing optical loss, both DLARC and QLARC enhanced the external quantum efficiency (EQE) of IMM3J solar cells, thus increasing the short-circuit current (Jsc) by 29.4% and 32.9%, respectively, compared to uncoated solar cells (AM0, 1-sun). The IMM3J solar cell with QLARC achieves a power conversion efficiency (PCE) of 31.8%, which is higher than that of the cells without ARC (23.7%) and with DLARC (30.6%). In comparison with DLARC, the nano-MgF2/ZnS/MgF2/ZnS demonstrated better broadband antireflection properties and enhanced electrical performance in IMM3J solar cells, as confirmed by simulation and experiment.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications.
