Dialkoxynaphthalene as an electron-rich unit for high-performance polymer solar cells with large open circuit voltages

Dialkoxynaphthalene is a simple aromatic building block, which can be synthesized easily in a large scale. In this work, two dialkoxynaphthalene derivatives were copolymerized with electron-withdrawing benzothiadiazole (BT) derivatives to afford three donor-acceptor copolymers, PNDTBT, PNT2FTBT and PN2FTBT. The three copolymers have diverse bandgaps ranged from 1.73 to 1.86 eV, and deep HOMO energy levels up to -5.61 eV. Thermogravimetric analysis and electrochemical measurements show that these copolymers have good thermal and environment stability. The hole mobilities of these copolymers were investigated using the space charge limited current (SCLC) method as well as the organic field effect transistor (OFET) method. Polymer solar cells based on PNDTBT exhibit the best photovoltaic performance with a power conversion efficiency of 6.24% and a Voc of 0.94 V, much better than those of previously reported copolymers based on dialkoxynaphthalene.

Influences of the non-covalent interaction strength on reaching high solid-state order and device performance of a low bandgap polymer with axisymmetrical structural units

A high organic field-effect transistor mobility (0.29 cm2V -1s-1) and bulk-heterojunction polymer solar cell performance (PCE of 6.82%) have been achieved in a low bandgap alternating copolymer consisting of axisymmetrical structural units, 5,6-difluorobenzo-2,1, 3-thiadiazole. Introducing the fluorine substituents enhanced intermolecular interaction and improved the solid-state order, which consequently resulted in the highest device performances among the 2,1,3-thiadiazole-quarterthiophene based alternating copolymers.

Effects of fluorination on the electrochromic performance of benzothiadiazole-based donor - Acceptor copolymers

A series of thiophene and benzothiadiazole-based copolymers (PDAT-DTBT) is synthesized through Stille coupling polymerization with two mono- and di-fluorinated benzothiadiazole analogues: PDAT-DTBT-F (1F) and PDAT-DTBT-2F (2F). The introduction of fluorine atoms onto the conjugated polymer backbone is found to have a pronounced effect on the optical, electrochemical and morphological properties, which in turn, influences the electrochromic performance of the fabricated absorption/transmission type devices greatly. All the polymers switch reversibly between the colored neutral states (green/blue) to transmissive oxidized states. Systematic enhancement in the reduction process to sub-second speeds (2 C-1) and substantially improved ambient stability are observed upon fluorination of electron acceptors. Long-term stability testing of the PDAT-DTBT-F electrochromic device is carried out for up to 10 000 repeated redox cycles between the applied potentials of +1.6 and -1.6 V, without the observation of significant degradation.
