The present invention relates to a greenhouse, and more specifically relates to a greenhouse having a solar cell module for generating electricity by using light at a redundant wavelength not needed for plant cultivation. The greenhouse having a solar cell module according to the present invention has: a greenhouse structure which comprises a frame constituting a supporting structure and comprises a light-permeable member supported by means of the frame, and which has a cultivation space where plants are cultivated on the inside thereof a solar-cell module which is provided inside the greenhouse structure and comprises solar cells, a first optical member constituted so as to collect sunlight falling incident thereon through the light-permeable member, and a second optical member which is provided on the propagation pathway of the light collected by means of the first optical member, and is constituted so as to separate the collected light into light (B), which is in a redundant wavelength region not used for plant cultivation, and light (A), which is in a useful wavelength region, such that the light (B) in the redundant wavelength region shines on the solar cells and a third optical member which is provided inside the greenhouse structure and is configured to control the area of irradiation of the light (A) in the useful wavelength region, separated by means of the second optical member, such that the light (A) in the useful wavelength region shines in the cultivation space. The greenhouse having the solar cell module according to the present invention is able to cut down on energy since, after having separated out light in the redundant wavelength region from sunlight, same can be reused after having been shone onto the solar cells and converted into electrical energy.Linvention concerne une serre, et plus spécifiquement une serre comprenant un module de cellule solaire pour générer de lélectricité en utilisant la lumière à une longueur donde à redondance inutile
