The invention provides a light transmitting solar energy module. The module comprises a front plate, a packaging front film, a thin film solar cell, a packaging back film and a back plate, wherein thefront plate, the packaging front film, the thin film solar cell, the packaging back film and the back plate are up-down successively arranged. According to the invention, the transmittance of the visible light of the front plate and transmittance of the visible light of the packaging front film on the light receiving face of a thin film solar energy cell are larger than 85%, so photoelectric conversion rate of a light transmitting solar energy module is ensured; the packaging back film under the thin film solar cell is an infrared blocking adhesive film; and the back plate has the infrared blocking layer which effectively blocks the infrared light. By arranging light transmitting wire grooves in a solar energy cell, and considering light transmitting requirements of application occasions,a problem of great reduction of visible light transmittance or photoelectric conversion rate caused by blocking of the infrared rays in the prior art is avoided. The invention also provides a makingmethod of the light transmitting solar energy module.
