Plant factory capable of efficiently utilizing sunlight

A plant factory capable of efficiently utilizing sunlight relates to the technical field of plant factories, and adopts the technical scheme that the plant factory comprises an outer wall and a photovoltaic system, the outer wall comprises a steel frame, the photovoltaic system comprises a power generation glass curtain wall arranged on the steel frame, and the power generation glass curtain wall comprises double-sided film power generation glass. The indoor side of the power generation glass curtain wall is provided with a light filtering film, and the light filtering film is a red and blue light double-channel light filtering film. According to the utility model, solar rays are selectively transmitted and reflected by using the light filtering film, the solar rays are reasonably distributed to the photovoltaic module and crops by using the light transmission and double-sided power generation performance of the double-sided film power generation glass, and the installation space of the photovoltaic module an
