Molecular weight distribution of PCE11 chlorobenzene Soxhlet fraction by GPC. (Soxhlet extraction was carried out by using methanol, acetone, hexane and then chlorobenzene as washing solvents under argon. Chlorobenzene fraction was concentrated and then precipitated with methanol, dried under vacuum at 40 oC for 48 hours. GPC was carried out by using 1,2,4-trichlorobenzene as eluent at 140 oC by using polystyrene as standards).

PffBT4T-2OD (PCE11) is a low band-gap (1.65 eV) semiconducting polymer for organic photovoltaics (OPVs), which has reached power conversion efficiencies (PCEs) approaching 11% [1]. These efficiencies are a result of the high crystallinity of the polymer, providing excellent hole transport mobilities on the order of 10-2cm2V-1s-1, and the ability to use a thick active layer, resulting in improved light absorption.
The size and position of the alkyl chains of PffBT4T-2OD are critical to its temperature dependant aggregation properties, enabling control over the aggregation and crystallisation of the polymer to produce an efficient donor:acceptor film morphology.
Polymer PCE11 was targeted by reacting 4,7-bis(5-bromo-4-(2-octyldodecyl)thiophen-2-yl)-5,6-difluorobenzo[c][1,2,5]-thiadiazole with 2,5-bis(trimethylstannyl)thieno[3,2-b]thiophene engaging Stille Coupling reaction.

The structure of the high-performance (10 - 11%) devices was:
ITO / ZnO / PffBT4T-2OD:PC70BM (200 – 300 nm) / MoO3 or V2O5 (20 nm) / Al (100 nm)
PffBT4T-2OD:PC70BM solution details:
It is important to note that this solution (and the substrate being deposited onto) must be heated for spin casting, with the ideal temperature being 60 – 80°C. It is reported that a solution and substrate pre-heating temperature of 110°C should be used to allow for cooling that will occur before deposition.
