Photovoltaic cell with benzodithiophene-containing polymer

The invention relates to novel conjugated polymers containing repeating units comprising a halogenated benzene ring, a silolobithiophene moiety, and a benzofused heteroaromatic moiety, to methods for their preparation and educts or intermediates used therein, to polymer blends, mixtures and formulations containing them, to the use of the polymers, polymer blends, mixtures and formulations as organic semiconductors in organic electronic (OE) devices, especially in organic photovoltaic (OPV) devices and organic photodetectors (OPD), and to OE, OPV and OPD devices comprising these polymers, polymer blends, mixtures or formulations.

Conjugated polymers

Novel photoactive polymers, as well as related photovoltaic cells, articles, systems, and methods, are disclosed.

Photovoltaic cell containing novel photoactive polymer

Photoactive polymers are provided, as well as related photovoltaic cells, articles, systems, and methods comprising these photoactive polymers.

The present invention relates to certain polymeric compounds and their use as organic semiconductors in organic and hybrid optical, optoelectronic, and/or electronic devices such as photovoltaic cells, light emitting diodes, light emitting transistors, and field effect transistors. The present compounds can provide improved device performance, for example, as measured by power conversion efficiency, fill factor, open circuit voltage, field-effect mobility, on/off current ratios, and/or air stability when used in photovoltaic cells or transistors. The present compounds can have good solubility in common solvents enabling device fabrication via solution processes.

Conjugated polymers and their use in optoelectronic devices

There are described novel rhodamine color-forming compounds. The rhodamine color-forming compounds exhibit a first color when in a crystalline form and a second color, different from the first color, when in an amorphous form. Thermal imaging members containing these color-formers are also described.

Color-forming compounds and use thereof in imaging members and methods

There are described novel rhodamine dye compounds and imaging members and imaging methods, including thermal imaging members and imaging methods, utilizing the compounds. The dye compounds exhibit a first color when in the crystalline form and a second color, different from the first color, when in the liquid, amorphous form.

Dyes and use thereof in imaging members and methods

There are described novel fluorescein dye compounds and imaging members and imaging methods utilizing the compounds. The fluorescein dye compounds exhibit a first color when in the crystalline form and a second color, different from the first color, when in the liquid, amorphous form.

Dyes and use thereof in thermal imaging members and methods

Process for the preparation of novel dyes for use in imaging members

There are described novel rhodol dye compounds The dye compounds exhibit a first color when in the crystalline form and a second color, different from the first color, when in the liquid, amorphous form.
