Abstract: The application of the method of super-potential to the solution of the problems of cosmology with the tachyon fields is examined. The classes of exact solutions are found and the periods of time with the predominance of dark energy are established.

Keywords: cosmology, tachyon field, dark sector field, exact solutions.
