Abstract
(EN)
The aim of the present invention is to provide a solar cell which is arranged in a direction vertical to the advancing direction of light, i.e. a concentrating direction, so as to thereby maximize a light collection area and thus also maximize the efficiency of the cell. The solar cell (100) of the present invention consists essentially of: a light collecting unit (110) in which multiple light collecting means (111) for collecting solar light are arranged into an array or into a matrix so as to form a plate shape, wherein the advancing direction of the solar light, i.e. the light collecting direction along which the solar light advances, is referred to as a lower side and the opposite direction is referred to as an upper side; a light guide unit (120) arranged beneath the light collecting unit (110) so as to convert the direction of the solar light collected in the light collecting unit (110) to the direction vertical to the light collecting direction; and a power generating unit (130) provided at one side of the light guiding unit (120) and consisting of a solar battery cell array so as to generate power using the solar light which is converted by the light guiding unit (120) and is incident to the generating unit (130).
