The present specification relates to a fullerene derivative, an orgainic solar cell and a manufacturing method thereof. The purpose of the present specification is to provide a fullerene derivative, an organic solar cell and a manufacturing method thereof wherein the fullerene derivative has thermal stability, high solubility and electron mobility. An embodiment of the present specification provides a fullerene derivative represented by chemical formula 1. In the chemical formula 1, Cn is a fullerene of C_60 to C_84; p is an integer of 1 to 4, and if p is 2 or more, the parenthesized structure is the same or different; L means CRaRb; m is an integer of 0 to 3, and if m is 2 or more, L is the same or different from each other, X1 and X3 are the same or different from each other, and independently, are S; O; PR; CRR′; SO2; P(=O)R; or SiRR′, respectively; at least one of X1 and X3 is S; O; PR; SO_2; P(=O)R; or SiRR′, and R1, R2, Ra Rb and R′ are the same or different. |
