The invention relates to a solar cell structure () having at least one transparent photovoltaic cell (), in particular having a dye solar cell or a thin-film semiconductor cell. It comprises at least one polymer layer () 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 ().

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 Ror Ras substituents with compounds of the general formula RA or RA 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.

The disclosure is a probelike apparatus ( ) for spectroscopic analysis of a fluid medium ( ) by attenuated reflection. Two light beams from a light source ( ) impinge upon the boundary ( ) between a prism ( ) and the medium ( ) to be analyzed and the intensities of the light beams reflected at the boundary are measured in a detector unit ( ). 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.
