要約
(EN)
The invention regards application of lignin derivatives to a photoelectric transducer. The photoelectric transducer of the invention includes a semiconductor film as a thin film electrode, that is photosensitized by one or multiple lignin derivatives selected from the group consisting of: (a) a lignophenol derivative or a phenol derivative of lignin that is prepared by solvating a lignin-containing material with a phenol compound and adding an acid to the solvate; (b) a secondary derivative that is prepared by one reaction of the lignophenol derivative (a) selected among acylation, carboxylation, amidation, introduction of a crosslinking group, and alkali treatment; (c) a higher-order derivative that is prepared by at least two reactions of the lignophenol derivative (a) selected among acylation, carboxylation, amidation, introduction of the crosslinking group, and alkali treatment; (d) a crosslinked secondary derivative that is prepared by crosslinking the secondary derivative (b) obtained by the introduction of the crosslinking group; and (e) a crosslinked higher-order derivative that is prepared by crosslinking the higher-order derivative (c) obtained by the introduction of the crosslinking group.

L'invention concerne l'utilisation d'un dérivé de la lignine obtenu par introduction d'un composé phénolique dans la lignine, notamment dans une électrode à film mince semi-conducteur, ainsi qu'un élément de conversion photoélectrique, ou une cellule solaire renfermant celui-ci. En particulier, l'invention concerne un élément de conversion photoélectrique à électrode à film mince semi-conducteur, dépourvue de retardateurs de ressources de carbone, un élément de conversion photoélectrique ou une cellule solaire renfermant celui-ci. Dans l'élément de conversion photoélectrique, on utilise un film semi-conducteur amplifié par au moins un dérivé de la lignine choisi dans le groupe comprenant des dérivés de lignophénol, des dérivés du second ordre obtenus à partir des dérivés de lignophénol, des dérivés d'ordre élevé obtenus à partir des dérivés de lignophénol, des substances constituées par des dérivés du second ordre réticulés et des substances constituées par des dérivés d'ordre élevé réticulés.
