SOLAR CELLS INCORPORATING LIGHT-ACCUMULATING CIRCUITS Russian patent published in 2005 - IPC

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 - (X^{m + 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 X^{m + 1} are, essentially, chromophores (and again , they are preferably porphyrinic monocycles).

EFFECT: reduced thickness and weight of portable flexible solar cells.
