To realize substantial performance enhancement in the poly (3-hexylthiophene)/[6, 6]-pheny-C71-butyric acid methyl ester (P3HT/PC71BM)-based organic optoelectronic devices, a discontinuous layer consisting of nickel nanoparticles (Ni NPs) was introduced to embellish the indium tin oxide electrode. When the Ni layer with a thickness of 3 nm was introduced, photocurrent gain was enhanced nearly 300% at low bias without sacrificing any response speed in the obtained organic photodetectors, and power conversion efficiency of organic solar cells increased nearly by 30%. The improved performance of the polymer photodetectors was mainly attributed to the injection of secondary electrons due to hole..View full abstract
