PDT-S-T: A new polymer with optimized molecular conformation for controlled aggregation and π-π Stacking and its application in efficient photovoltaic devices

The correlation among molecular conformation, the crystallinity of the morphology, propensity for π-π stacking, J- versus H-aggregation, and photovoltaic performance have been studied based on two newly designed polymers, PBDTTT-S-T and PDT-S-T. The results show that more linear backbone structure is helpful to improve photovoltaic properties of the polymer, and therefore, molecular conformation should be considered for molecular design of photovoltaic polymers.

Single-junction organic solar cells based on a novel wide-bandgap polymer with efficiency of 9.7%

A novel wide-bandgap copolymer (PDBT-T1) is developed and applied in organic solar cells, which yield a high efficiency of 9.74% and a high fill factor of 75%. The high photovoltaic performance is due to efficient photogenerated exciton dissociation and charge collection in PDBT-T1-based solar cells. The results show that PDBT-T1 is an outstanding candidate as a wide-bandgap material for tandem (or multi-junction) organic solar cells.

Synthesis, characterization and photovoltaic properties of dithienobenzodithiophene-based conjugated polymers

Two new donor-acceptor typed conjugated polymers (P1 and P2) based on the large coplanar and more-extended donor dithieno[2,3-d:2,3-d′]benzo[1,2-b:4,5-b′]dithiphene and thienopyrroledione (TPD) units were synthesized. P1 and P2 have the same polymer backbone, but with different side chains, where P1 has 2-ethylhexyl side chains and P2 has the longer branched 4-ethyoctyl side chains. The solubility measurements show that P2 with longer branched 4-ethyloctyl side chain has better solubility in organic solvents than that of P1. The optical, electrochemical and photovoltaic properties were investigated. P1 and P2 show the very same absorption features in both solution and film states indicating an enhanced molecular planarity of the polymer chains in P1 and P2, which benefits from the large coplanar dithieno[2,3-d:2,3-d′]benzo[1,2-b:4,5-b′]dithiphene unit. The band-gaps of P1 and P2 are at 1.83?eV and 1.74?eV, respectively. The solar cells with P1 or P2 as the electron donor component and PC71BM as the electron acceptor were fabricated and measured under AM 1.5G illumination at 100?mW?cm?2. The results show that the P2/PC71BM-based device showed a moderate power conversion efficiency of 2.86%, which is ～50% improvement in comparison with P1/PC71BM-based device.
