The invention discloses polythiophene compound, intermedium thereof and a preparation method and application of the same two to a solar battery. The intermedium of the polythiophene compound has the structural formula I, and the polythiophene compound has the structural formula II, wherein m is more than or equal to 10 and is less than or equal to 100, and n is more than or equal to 0 and is less than or equal to 100. The novel polythiophene compound is obtained in such a way that a lateral group is connected to an electron-donating group, thereby the conjugate length of a main chain of polythiophene is increased, the carrier mobility and the sun light absorbance of polymer are improved. The polymer with different compounding ratios can be obtained by adjusting the proportion of an electron-donating lateral group to a 3-hexylthiophene as required. The polythiophene compound has correct structure, simple preparation method, easy operation and high yield. Containing the electron-donating ...
