Enhanced Photovoltaic Performance of Inverted Polymer Solar Cells Utilizing Multifunctional Quantum‐Dot Monolayers

This is the authors' abstract. We don't add key points for this paper.

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]]):PC71BM ([6,6]-phenyl-C71-butyric acid methyl ester) active layer.
