Two batches of P3HT were used in this study: (1) for doping with Mes 2 B + [B(C 6 F 5 ) 4 ] À , P3HT (weight average molecular weight M w of 50-100 kg mol À1 , regioregularity 490%) from Sigma-Aldrich GmbH was used. (2) For doping studies with B(C 6 F 5 ) 3 , P3HT (M w = 60.2 kg mol À1 , regioregularity of 97.6%) from Merck KGaA was used. B(C 6 F 5 ) 3 was obtained from TCI Deutschland GmbH, while Mes 2 B + [B(C 6 F 5 ) 4 ] À ) was synthesized as previously described. 48, (link)49 (link) Anhydrous chlorobenzene (CB) and 1,2-dichlorobenzene (o-DCB) were purchased from Sigma-Aldrich GmbH (499.9% purity, inhibitor-free), and were further degassed via three freeze-pump-thaw cycles before using in solution preparation.
The doping technique used in this work is solution-mixed doping: (1) separate stock solutions of P3HT and the dopants were prepared inside a glovebox (o0. (2) The dopant solution and P3HT solution were mixed in a predefined volume proportions to control the dopant concentration.
Thin films were prepared via spin-coating using standard laboratory spin-coaters at various speeds (1000-6000 rpm) and times (1-2 min).

The donor, acceptor, and dopant were mixed at the weight ratio of D: A1: A2 = 1: 1.2: x (x = 0.1, 0.5, 1.0) in anhydrous chlorobenzene (CB) (99.8%, Sigma-Aldrich Inc., St. Louis, MO, USA). The mixture was stirred at 60 °C for 19 h to obtain the coating solution of the active layer. The prepared coating solution needs to be heated to 120 °C for 20 min before the coating process.

The acceptor molecule, [6,6]-Phenyl C71 butyric acid methyl ester (PC71BM) was purchased from Solarmer Materials Inc. A bare Si (0.001–0.005 Ohm.cm, Namkang Hightech) and micro cover glass (VWR Cat No 48366-067) were used as a bottom substrate and top cover, respectively. Corning glass substrates (Fair & Cheer Inc.) were used for spectroscopic studies. The substrates were cleaned with toluene, acetone, and isopropyl alcohol and then blow-dried with a stream of nitrogen to remove contaminants. Poly(sodium 4-styrenesulfonate) (PSS) average Mw ~70,000, powder (Sigma-Aldrich Inc.) was used as a sacrificial layer to transfer the polymer films for TEM characterization.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
