Semitransparent battery and seawater desalination coupling system based on solar spectrum frequency division

The invention provides a semitransparent cell and seawater desalination coupling system based on solar spectrum frequency division, which comprises a system frame, the system frame is provided with a multi-stage seawater desalination system, a semitransparent solar cell panel is arranged above the multi-stage seawater desalination system, and the semitransparent solar cell panel is arranged above the multi-stage seawater desalination system. The semitransparent solar cell panel comprises a photovoltaic glass plate, a semitransparent cell and a solar absorber which are laminated in sequence, and the layers are bonded by EVA (Ethylene Vinyl Acetate) materials. According to the invention, the multi-stage interface distillation device is coupled to the semitransparent battery backboard, and the waste heat of the battery and the directly transmitted solar energy are utilized to circulate the steam condensation latent heat of each distillation stage, so that the relatively high desalination yield is obtained under
