Yi-Ming Chang, Rui Zhu, Eric Richard, Chun-Chao Chen, Gang Li and Yang Yang Electrostatic Self-Assembly Conjugated Polyelectrolyte-Surfactant Complex as an Interlayer for High Performance Polymer Solar Cells Advanced Functional Materials 22
A simple method is demonstrated to improve the film-forming properties and air stability of a conjugated polyelectrolyte. Using this complex as a cathode interface layer, a high power conversion efficiency of 4% can be obtained in poly(3-hexylthiophene):[6,6]-phenyl C61 butyric acid methyl ester (P3HT:PCBM) solar cells together with improved stability in air. Moreover, ≈20% performance enhancement can also be achieved when the complex is used to replace calcium metal for low bandgap polymer-based bulk heterojunction (BHJ) systems.
