The present invention provides a concentration method of sunbeams for a photovoltaic power generation and lens and apparatus used in the method. A method of concentrating sunbeams according to the present invention is characterized in that as a method of concentrating sunbeams on a concentration surface of a solar cell that is installed on a photovoltaic power generator, it comprises steps of installing a concentration lens ( 20 ) on the upper side of a solar cell in parallel to the concentration surface, which includes a plurality of unit lens ( 21 ) having areas corresponding to the areas of the concentration surface, and irradiating and concentrating superposingly the sunbeams incident on the respective unit lens to the concentration surface. As a result, the present invention has advantageously a best performance in a solar cell.
