Abstract
This study investigates the optical performance of the MgF2 layer coated on the SiNx-based multicrystalline silicon (mc-Si) solar cell and optimizes the MgF2 layer thickness. The experimental results are qualitatively consistent with the simulation results. The absolute efficiency of 6-inch mc-Si solar cells improve by 0.5 to 0.7% for different MgF2 thicknesses and approach 17.2% absolute efficiency by measuring with an AM1.5G solar simulator. The optimized thickness of MgF2 is 100 to 125 nm in ambient condition.
