How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The role of nonradiative inductive-resonance energy transfer between molecules of Coumarine-7 and rhodamine dyes in the conversion of light into electric energy is studied. It is ascertained that the co-sensitization of a TiO2 solar cell by donor and acceptor molecules leads to an increase of the efficiency of conversion of light to energy. The measurements show that it is due to a widening of the photosensitivity of a cell into the blue region of the spectrum. The increase of the total energy absorbed promotes increasing the number of generated charge carriers at the interface of TiO2 and dyes.
