TL;DR: In this paper, the authors applied a C&H process with a P3HT/PCBM m-xylene solution to generate P3H:PCBM nanofibril composite films and found that the hole transport was 2.6 times faster in the thickness direction and 6.5 times more conductive in the in-plane direction.

Enhanced Air Stability of Polymer Solar Cells with a Nanofibril-Based Photoactive Layer
TL;DR: Investigating the photo-oxidation behavior of a bulk-heterojunction (BHJ) photoactive film made of single-crystalline poly(3-hexlythiophene) (P3HT) nanofibrils and fullerene derivatives showed significantly enhanced air stability under sunlight, whereas the PCE of the conventional BHJ solar cell decreased to 20% of its initial PCE under the same experimental conditions.
