TWO-COMPONENT ELECTRON-SELECTIVE BUFFER LAYER AND PHOTOVOLTAIC CELLS BASED THEREON Russian patent published in 2016 - IPC C07C57/50 C07F9/38 H01L51/42 H01L31/04 H01L27/28 B82B1/00 B82B3/00

Abstract RU 2595342 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to use of fullerene derivatives in optoelectronic devices such as photovoltaic cells of formula (I): X-F-(Z-Y-M)_r(I), where F is [60]fullerene or [70]fullerene, M is a COOH, r is an integer from 2 to 8, Z is a group -(CH₂)_n-, Ar, or -S-, n is an integer from 1 to 12, Y represents aliphatic C₁-C₁₂ carbon chain, Ar is phenyl, biphenyl or naphthyl and X is H, Cl or C₁-C₁₂ carbon chain independent from Y.

EFFECT: proposed is a new application of said compounds in electron-selective buffer layer organic photovoltaic cell, making it possible to increase efficiency of solar batteries.
