摘要
In this work, a composite light-trapping strategy based on [email protected]2 nanoparticles embedded inside the active layer and an antireflection coating on the top surface is proposed to obtain broadband absorption improvement in carbon-based perovskite solar cells (C–PSCs). The effects of geometrical parameters, including the radius and period of Ag nanoparticles, the thickness of the protective SiO2 shell and the thickness of the antireflection coating, on the light absorption are investigated using the finite-difference time-domain (FDTD) method. Simulation results illustrate that nearly full absorption of light can be achieved with the optimized structure parameters for a 600 nm thick perovskite layer using the composite light-trapping scheme. The short-circuit current density (JSC) exhibits an improvement of 24.8% relatively compared to the C-PSC without light management. The proposed composite light-trapping structure allows improved light utilization and saved material consumption in C–PSCs.
