Abstract: A photovoltaic module for an agricultural greenhouse includes a front plate, intended to be in contact with the sunlight, a back substrate and an assembly of photovoltaic cells arranged between the front plate and the back substrate. The photovoltaic module has a cell packing factor of substantially between 0.2 and 0.8, and includes at least one layer of a light-cascade doped material enhancing photosynthesis for absorbing the sunlight in at least one range of wavelengths for retransmitting same in at least a second range of wavelengths, enhancing the photosynthesis of at least one plant species.

Abstract: The present disclosure relates to a photovoltaic generator, including at least one block with transparent walls and at least one reflecting wall, as well as photovoltaic cells, wherein the walls opposite the reflecting wall are transparent and include optically active dopants that transform incident solar radiation into radiation, the spectrum of which is shifted towards the range of the photovoltaic cells with the highest sensitivity, and at least one transparent wall is covered with a dichroic filter.

Abstract: The present disclosure relates to a rack with double photovoltaic glazing including a frame with a rabbet, the rabbet containing at least two substantially parallel transparent sheets, i.e. a front sheet intended for receiving sunlight and a rear sheet, wherein the double-glazed rack includes photovoltaic cells located at the back of the rabbet and a coating made of a material forming a cascade of light.
