Nano metal-enhanced power conversion efficiency in CH3NH3PbI3 solar cells

Nano metal-enhanced power conversion efficiency (PCE) in CH3NH3PbI3 solar cells utilizing the forward scattering effect of metal nanoparticles has been researched in this paper by finite difference time domain method. Two structures are designed in the research to explore this feasibility, by adjusting the materials, sizes and surface coverages of metal nanoparticles, both of them exhibit the exciting results bringing the max PCE enhancements by 12.18% and 8.03% respectively. Especially, considering the huge handleability of the second structure, this method has large applications in further improving the performance for other perovskite solar cells.
