Synthesis and Characterization of a highly crystalline benzotriazole-selenophene copolymer semiconductor

A new donor (D)-acceptor (A) type copolymer semiconductor based on benzotriazole and selenophene was designed and synthesized. The benzotriazole-selenophene copolymer (P(BTz-Se)) showed a highly crystalline lamellar packing structure with a lamellar interchain distance of 1.77 nm and large mean crystalline domain size of 17.26 nm. The average field-effect hole mobility of an as-cast P(BTz-Se) film was 2.93×10?4 cm2 V?1 s?1. After annealing the polymer film at 150 °C, a 55-fold enhanced average hole mobility (1.61×10?2 cm2 V?1 s?1) with high on/off current ratio (1.7×106) was observed. In addition to the great charge carrier mobility, P(BTz-Se) showed a narrow energy bandgap (1.69 eV) and broad optical absorption range with excellent absorption coefficient, suggesting that this copolymer semiconductor may also be a good electron donor in organic photovoltaic devices.

A selenophene-containing conjugated organic ligand for two-dimensional halide perovskites

A selenophene-containing conjugated organic ligand, 2-(4′-methyl-5′-(5-(3-methylthiophen-2-yl)selenophen-2-yl)-[2,2′-bithiophen]-5-yl)ethan-1-aminium (STm), was synthesized and incorporated into a Sn(ii)-based two-dimensional perovskite, (STm)2SnI4. The band offset between the perovskite and ligand can be fine-tuned by introducing the STm ligand. Both field-effect transistor and light-emitting diode devices based on (STm)2SnI4films exhibit high performance and enhanced operational stability.

Ortho-bridged perylene diimide dimer and preparation method thereof as well as application thereof in organic photovoltaic devices

The invention provides an ortho-bridged perylene diimide dimer (formula I), a preparation method and an application thereof in the organic photovoltaic field. The invention further relates to an organic solar cell of the compound and a preparation method of the organic solar cell. Compared with a PDI monomer molecule, a formed twisted dimer structure is capable of effectively weakening excessive aggregation among PDI molecules, so that the phase size is reduced. Meanwhile, by virtue of ortho-bridging, the deformation of a PDI inner core caused by waist bridging can be avoided, so that certain planarity and relatively strong pi-pi accumulation can be maintained, and relatively high electronic mobility can be obtained. The PDI dimer is taken as a receptor material and is combined with an electron donor polymer so as to prepare the organic solar cell, so that very high photoelectric conversion efficiency is realized.

n-Type Semiconducting Naphthalene Diimide-Perylene Diimide Copolymers: Controlling Crystallinity, Blend Morphology, and Compatibility Toward High-Performance All-Polymer Solar Cells

Knowledge of the critical factors that determine compatibility, blend morphology, and performance of bulk heterojunction (BHJ) solar cells composed of an electron-accepting polymer and an electron-donating polymer remains limited. To test the idea that bulk crystallinity is such a critical factor, we have designed a series of new semiconducting naphthalene diimide (NDI)-selenophene/perylene diimide (PDI)-selenophene random copolymers, xPDI (10PDI, 30PDI, 50PDI), whose crystallinity varies with composition, and investigated them as electron acceptors in BHJ solar cells. Pairing of the reference crystalline (crystalline domain size Lc = 10.22 nm) NDI-selenophene copolymer (PNDIS-HD) with crystalline (Lc = 9.15 nm) benzodithiophene-thieno[3,4-b]thiophene copolymer (PBDTTT-CT) donor yields incompatible blends, whose BHJ solar cells have a power conversion efficiency (PCE) of 1.4%. However, pairing of the new 30PDI with optimal crystallinity (Lc = 5.11 nm) as acceptor with the same PBDTTT-CT donor yields compatible blends and all-polymer solar cells with enhanced performance (PCE = 6.3%, Jsc = 18.6 mA/cm2, external quantum efficiency = 91%). These photovoltaic parameters observed in 30PDI:PBDTTT-CT devices are the best so far for all-polymer solar cells, while the short-circuit current (Jsc) and external quantum efficiency are even higher than reported values for [70]-fullerene:PBDTTT-CT solar cells. The morphology and bulk carrier mobilities of the polymer/polymer blends varied substantially with crystallinity of the acceptor polymer component and thus with the NDI/PDI copolymer composition. These results demonstrate that the crystallinity of a polymer component and thus compatibility, blend morphology, and efficiency of polymer/polymer blend solar cells can be controlled by molecular design.

Side chain engineering of n-type conjugated polymer enhances photocurrent and efficiency of all-polymer solar cells

Side chain engineering of an n-type polymer provides a means of maintaining solubility while increasing crystallinity and electron mobility, leading to enhanced photocurrent. Bulk heterojunction solar cells composed of a side chain engineered copolymer (PNDIS-30BO) as acceptor and PSEHTT as donor give 10.4 mA cm-2 photocurrent and 4.4% efficiency. the Partner Organisations 2014.

All-polymer solar cells with 3.3% efficiency based on naphthalene diimide-selenophene copolymer acceptor

The lack of suitable acceptor (n-type) polymers has limited the photocurrent and efficiency of polymer/polymer bulk heterojunction (BHJ) solar cells. Here, we report an evaluation of three naphthalene diimide (NDI) copolymers as electron acceptors in BHJ solar cells which finds that all-polymer solar cells based on an NDI-selenophene copolymer (PNDIS-HD) acceptor and a thiazolothiazole copolymer (PSEHTT) donor exhibit a record 3.3% power conversion efficiency. The observed short circuit current density of 7.78 mA/cm 2 and external quantum efficiency of 47% are also the best such photovoltaic parameters seen in all-polymer solar cells so far. This efficiency is comparable to the performance of similarly evaluated [6,6]-Phenyl-C 61-butyric acid methyl ester (PC60BM)/PSEHTT devices. The lamellar crystalline morphology of PNDIS-HD, leading to balanced electron and hole transport in the polymer/polymer blend solar cells accounts for its good photovoltaic properties.
