In this report, we demonstrate that the metal nanoparticles can improve the performance of organic solar cells (OSCs) by boosting the internal quantum efficiency (IQE) of the devices even without a notable plasmonic optical gain.[1] A hybrid layer platform in combination of silver nanoparticles (AgNPs) and polyethylenimine-ethoxylated (PEIE) layer maximized the IQE of the OSCs to nearly 100 %. 2D surface characterization confirmed the AgNPs provided the short path and funneled charge carriers to a cathode, which would effectively raise the carrier mobility.Moreover, the hybrid layer doubled the device half-efficiency lifetime due to longer retention of the improved mobility.
