FIELD: chemistry.SUBSTANCE: invention relates to novel redox pairs for the application in dye-sensitised solar cells DSSC. The redox pairs are formed by the general formula (bipyridine derivative)nMe(Ion)m, where the bipyridine derivative iswhere R2, R3 is any substituent from the group methyl, ethyl, propyl, butyl, pentyl, hexyl, Me is a metal from the group Cr, Mo, Nd, Ni, Pd, Pt, Ir, Co, Rh, Cu, W, Mn, Ta, Fe, Ru, Ion - a counterion, is any of the group ClO?, Cl, I, BF?, PF?, CFSO?, n, m correspond to the metal ion valence. The novel redox pairs (version) and an electrolyte for the application on DSSC are also claimed.EFFECT: novel redox pairs are applied in DSSC and possess the lowest redox-levels for increasing the open circuit voltage.3 cl, 1 dwg, 1 tbl, 3 ex Изобретение относится к новым редокс парам для применения в сенсибилизированных красителем солнечных элементах СКСЭ. Редокс-пары образованы по общей формуле (производное бипиридина)nMe(Ion)m, где производное бипиридина есть:где R1, R2, R3 - любой заместитель из ряда метил, этил, пропил, бутил, пентил, гексил, Me - металл из ряда Cr, Mo, Nd, Ni, Pd, Pt, Ir, Co, Rh, Cu, W, Mn, Та, Fe, Ru, Ion - противоион - любой анион из ряда ClO , Cl, I, BF , PF , CFSO , n, m - соответствуют валентности иона металла. Также предложены новые редокс-пары (вариант) и электролит для применения в СКСЭ. Новые редокс-пары применяются в СКСЭ и обладают наинизшими редокс-уровнями для повышения напряжения холостого хода. 3 н.п. ф-лы, 1 ил., 1 табл., 3 пр.
