N2 - A weak electron acceptor, 4,9-bis(5-bromothiophen-2-yl)-2-(2-ethylhexyl)- benzo[f]isoindole-1,3-dione (BIDO) was designed and synthesized. Polymer P1 derived from BIDO and 9,9-dioctylfluorene-2,7-diboronic acid bis(1,3-propanediol) ester by Suzuki cross-coupling reaction has a band gap of 2.41 eV. To expand the absorption range, a different amount of BIDO was copolymerized with a diketopyrrolopyrrole monomer to produce a series of copolymers Pa-c. The optical properties, electrochemical behavior, and energy levels of these four copolymers were investigated. The photovoltaic properties copolymers Pa-c were studied. A photovoltaic device containing Pc and [70]PCBM with a ratio of 1:2 had a power conversion efficiency of 1.17%.

Efficiency Enhancement of P3HT: PCBM Based Organic Photovoltaic Devices via Incorporation of Bio-synthesized Gold Nanoparticles

Polymer solar cells (PSCs) are commonly composed of a blend film of a conjugated polymer donor and a soluble C60 derivative acceptor sandwiched between an ITO anode and a low-workfunction metal cathode. Poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C-61-butyric acid methyl ester (PCBM) are the most widely used donor and acceptor materials, respectively. However, the low LUMO energy level of PCBM limits the open circuit voltage (oc) of the P3HT-based PSCs to ca. 0.6 V. Here we synthesized a new soluble C60 derivative, indene−C60 bisadduct (ICBA), with a LUMO energy level 0.17 eV higher than that of PCBM. The PSC based on P3HT with ICBA as acceptor shows a higher oc of 0.84 V and higher power conversion efficiency (PCE) of 5.44% under the illumination of AM1.5, 100 mW/cm2, while the PSC based on P3HT/PCBM displays a oc of 0.58 V and PCE of 3.88% under the same experimental conditions. The results indicate that ICBA is an alternative high-performance acceptor and could be widely used in high-performance PSCs.

Novel PCBM analogues containing thienyl groups were synthesized. The morphology of the bulk hetero films of the obtained methanofullerenes was different from that of PCBM. To some extent, the aggregation of P3HT was restricted by the large volume of 2-BThCBM (3a) and es-TThCBM (3d). Among the obtained methanofullerenes, es-TThCBM (3d) exhibited the best solubility. It is a rare methanofullerene that has greater solubility than PCBM. The improvement in solubility by just adding an ester group is very informative and promising for further development of methanofullerenes. Bulk heterojunction solar cells using newly synthesized methanofullerenes are being fabricated and evaluated.
