Organic photovoltaic devices comprising fullerenes and derivatives thereof |
摘要 |
Photovoltaic cells comprising an active layer comprising, as p-type material, conjugated polymers such as polythiophene and regioregular polythiophene, and as n-type material at least one fullerene derivative. The fullerene derivative can be C60, C70, or C84. The fullerene also can be functionalized with indene groups. Improved efficiency can be achieved. |

1. A composition adapted for a photovoltaic device comprising a mixture comprising: (I) at least one p-type material, wherein the p-type material comprises a conjugated polymer, and (ii) at least one n-type material, wherein the n-type material comprises a fullerene derivative represented by:
F*—(R)n and solvates, salts, and mixtures thereof, wherein n is at least one, F* comprises a fullerene having a surface which comprises six-membered and five-membered rings; R comprises an optionally substituted indene; and wherein R is covalently bonded to the fullerene by two bonds and wherein the fullerene comprises a C60 fullerene. |
