OPTICAL LAYER FOR A LIGHT-ADJUSTING TYPE SOLAR POWER-GENERATING MODULE, LIGHT-ADJUSTING TYPE SOLAR POWER-GENERATING MODULE AND LIGHT-ADJUSTING TYPE SOLAR POWER-GENERATING PANEL

摘要

An optical layer for a light control type solar photovoltaic module, a light control type solar photovoltaic module, and a light control type solar photovoltaic panel having an excellent directionality to the sunlight are provided.;An optical layer 4 for a light control type solar photovoltaic module includes an entrance surface 11 and an exit surface 12 and is arranged opposite photovoltaic cells 6 that convert light into electric energy. A number of prismatic optical elements are formed in at least one of the entrance surface 11 and the exit surface 12, each of the prismatic optical elements is on a common plane S1 defined by a common base shared by the prismatic optical elements adjacent to each other, and a prism axis 7 of each of the prismatic optical elements is inclined toward a predetermined direction with respect to a direction perpendicular to the common plane.
