PHOTOVOLTAIC METHOD AND DEVICE FOR THE PRODUCTION OF ELECTRIC ENERGY AT LOW LUMINOSITY AND OUTSIDE EXPOSURE TO A LIGHT SOURCE

摘要

The invention relates to a photovoltaic device comprising a module (1) consisting of photovoltaic cells. The invention is remarkable in that the surface (2) of this photovoltaic module (1) intended to be exposed to daylight or other light source (S) is covered with a layer of photoluminescent pigments (3) having the capacity to be permeable to daylight and artificial light, and to store a portion thereof to restore it during the day in low light and / or in the dark toward said surface (2, 2 ').
