Polyethylenimine ethoxylated (PEIE)/monolayered quantum dots (QDs) play a multifunctional role as the electron transport layer and the absorption layer, in addition to causing surface plasmon resonance effects, for improving photovoltaic performance. This leads to a power conversion efficiency increase of up to 8.1% using a PTB7 (poly[[4,8‐bis[(2‐ethylhexyl)oxy]benzo[1,2‐b:4,5‐b′]dithiophene‐2,6‐diyl][3‐fluoro‐2‐[(2‐ethylhexyl)carbonyl]thieno[3,4‐b]thiophenediyl]]):PC 71 BM ([6,6]‐phenyl‐C 71 ‐butyric acid methyl ester) active layer.
