Greenhouse photo-thermal and photovoltaic combined device based on double-glass assemblies

The invention discloses a greenhouse photo-thermal and photovoltaic combined device based on double-glass assemblies. The greenhouse photo-thermal and photovoltaic combined device based on double-glass assemblies comprises a structure main body, the structure main body comprises an exhaust cavity, a photo-thermal and photovoltaic cavity and an air suction cavity which communicate in sequence, and an exhaust port communicating with an exhaust cavity is formed in a top part of the structure main body; double-glass photovoltaic assemblies and metal wing-shaped radiators fixed with the double-glass photovoltaic assemblies through heat-conducting glue are arranged in the photo-thermal and photovoltaic cavity, and solar cell monomers are arranged on the double-glass photovoltaic assemblies in a matrix manner; and a front surface of the photo-thermal and photovoltaic cavity is sealed through photovoltaic glass, the exhaust cavity is gradually shrunk in a direction away from the structure main body to form an exhaust
