PHOTOVOLTAIC DEVICE WITH ENHANCED LIGHT HARVESTING |
摘要 |
A photovoltaic device optical system for enhanced light harvesting with a transparent layer of dielectric material having on one side an array of micro-lenses and on the opposite side a metal reflective film with an array of openings. The micro-lenses focus direct sunlight impinging thereon through the openings, to separate direct sunlight and diffuse sunlight. The photovoltaic device has a first photovoltaic cell system for the exploitation of the direct sunlight located in the opposite hemi-space of the micro-lenses array with respect to the plane of the openings array and a second photovoltaic cell system for the exploitation of diffuse sunlight, located in the same hemi-space containing the micro-lenses array with respect to the plane of the openings array.
