FIELD: solar light sources. ^ SUBSTANCE: proposed solar cell noted for high effectiveness of more than 5% has first light accumulating circuit incorporating first substrate that carries first electrode and layer of light-accumulating bars electrically connected to first electrode. Each of light-accumulating bars incorporates polymer of formula(I): X1 - (Xm + 1)m, (I) where m is at least 1 and may constitute from two, three, or four to 20 and more; X1 is charge separation group (and preferably porphyrinic monocycle that may be, essentially, one ligand of double-tier sandwich compound) in excited state with energy equal to or lower than that of X2; and groups of X2 to Xm + 1 are, essentially, chromophores (and again , they are preferably porphyrinic monocycles). ^ EFFECT: reduced thickness and weight of portable flexible solar cells. ^ 25 cl, 58 dwg |
