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.
