CONCENTRATOR PHOTOVOLTAIC UNIT, CONCENTRATOR PHOTOVOLTAIC MODULE, CONCENTRATOR PHOTOVOLTAIC PANEL, AND CONCENTRATOR PHOTOVOLTAIC APPARATUS |
摘要 |
In a concentrator photovoltaic unit configured to guide sunlight concentrated by a primary concentrating portion to a power generating element by means of a secondary concentrating portion, the secondary concentrating portion includes: a secondary lens having a three-dimensional shape; and a cover portion being translucent and having a refractive index higher than that of air and lower than that of the secondary lens, the cover portion covering at least a surface on which the sunlight is incident in a surface of the secondary lens, in a thin film shape extending along the surface on which the sunlight is incident. By arranging a large number of the units, a concentrator photovoltaic module can be configured. By arranging a large number of the concentrator photovoltaic modules, a concentrator photovoltaic panel can be configured. By further providing a driving device for tracking the sun, a concentrator photovoltaic apparatus can be configured. |
