摘要：

We report here a new method to improve the performance of GaInP solar cells by fabricating Ag nanoparticles (Ag NPs) atop the devices through a simple wet-chemical method. The size and density of Ag NPs can be easily optimized by changing the concentration of AgNO3 solution and/ or the reaction time. The Ag NPs support surface plasmonic resonances (SPRs) and thus greatly increase light absorbance and photocurrent responses of the solar cells by the scattering and re- reflection of incident light. We find that, for a Ag NPs density of similar to 3.37 x 10(10) cm(-2), the short-circuit current density (J(sc)) increases by 19.5% from 14.9 to 17.8 mA cm(-2), and the power conversion efficiency (PCE) increases by 20.4% from 15.2% to 18.3%.
