摘要:
This invention relates to process for preparing fluorinated dyes selected from the group consisting of compounds of the general formulae (I) and (III) and mixtures thereof by reacting the corresponding compounds which do not have R12 or R30 as substituents with compounds of the general formula R12A or R30A where A is selected from the group consisting of I and Br, the compounds obtained from said process and the use of these fluorinated dyes in electrophoretic displays.

摘要:
A fluorescence conversion solar cell based on one or more panels composed of polymer doped with at least one fluorescent dye and/or glass panels coated with the doped polymer and photovoltaic cells mounted on the edges of the panels, which comprise one or more fluorescent dyes based on terrylenecarboxylic acid derivatives or a combination of these fluorescent dyes with further fluorescent dyes.
摘要:
The disclosure is a probelike apparatus (16) for spectroscopic analysis of a fluid medium (19) by attenuated reflection. Two light beams from a light source (11) impinge upon the boundary (18) between a prism (17) and the medium (19) to be analyzed and the intensities of the light beams reflected at the boundary are measured in a detector unit (22). The two light beams differ in their angle of incidence on the boundary and/or in their polarization state. Measurement is preferably carried out under total reflection.

The invention relates to a solar cell structure (10) having at least one transparent photovoltaic cell (42), in particular having a dye solar cell or a thin-film semiconductor cell. It comprises at least one polymer layer (36) which is provided with a fluorescent material, or a mixture of a plurality of fluorescent materials, and covers the at least one transparent photovoltaic cell (42).
