Abstract: 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.

Abstract: The present invention relates to a light condensing apparatus for solar photovoltaic generation, and more particularly, to a light condensing apparatus for solar photovoltaic generation in which a integration degree of sunlight that is irradiated on a solar cell is improved to a maximum energy efficiency. A light condensing apparatus for solar photovoltaic generation according to the present invention comprises a supporting member that is fixed to the ground, a rotation member that is installed rotatably about the X-axis on the supporting member, a light condensing module that is installed rotatably about the Y-axis and condenses sunlight to convert it into electrical energy, and a first and second angle adjustment device for rotating the rotation member and at least one light condensing module that is installed such that a directivity angle of at least one light condensing module is adjusted automatically depending on the changes of altitude of the sun and the diurnal motion.

Abstract: A photovoltaic power generating unit is disclosed. The photovoltaic power generating unit includes a plurality of solar cells, a concentrating lens for concentrating sun light on the solar cell, which is installed on the vertical upper part of the solar cell, and a concentrating type solar cell module provided with a protective member which is attached to the lower part thereof for protecting the solar cell from external impact. In addition, the photovoltaic power generating unit of the present invention includes a radiating part for dissipating heat created in the solar cell module to the atmosphere. The radiating part consists of a radiating plate bonded to the lower part of the protective member through a thermal resin bonding agent and a plurality of radiating fins protruding downwardly from the radiating plate. Meanwhile, a frame is installed on both edges of the solar cell module to entirely support the solar cell module, and a frame extension part protruding downwardly from the frame is arranged.
