Abstract
The present invention relates to a photovoltaic yarn and production method wherein electrical conduction is enabled by the photovoltaic yarn comprising a texturized yarn (2) with a cathode layer (4), an active layer (6) and an anode layer (8) coating thereon, the photovoltaic yarn can generate electricity utilizing the solar light, and which is developed especially to be used in textile industry.
Claims19
A photovoltaic yarn, comprising:
- at least one texturized yarn,
- at least one intermediate layer covering the texturized yarn to increase the adhesion strength of the yarn,
- at least one cathode layer comprising a gallium-indium alloy coats on the yarn by means of the intermediate layer,
- at least one active layer comprising an electron donor material selected from a group consisting of p-type poly (3-hexylthiophene) (P3HT), poly [N-9′-hepta-decanyl-2,7-carbazole-alt-5,5-(4′,7″-di-2-thienyl-2′,1′,3′-benzothiadiazole)](PCDTBT), poly Poly [2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta [2,1-b;3,4-b′]dithiophene)-alt-4,7(2,1,3-enzothiadiazole)] (PCPDTBT), poly({4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl}{3 -fluoro-2-[2-ethylhexyl) carbonyl]thieno[3,4-b]thiophenediyl}) (PTB7) and semi conductive polymers and an electron acceptor material selected from a group consisting of n-type carbon-60 derived [6,6]-phenyl-C61-butyric acid methyl ester (PCBM);
- (6,6)-phenyl C71-butyric acid methyl ester (PC71BM), 1′,1″,4′,4″-Tetrahydro-di[1,4]methanonaphthaleno[1,2:2′,3′,56,60:2″,3″][5,6]fullerene-C60, C60 derivative, indene-C60 bisadduct (ICBA) and semi conductive polymers,
