Photovoltaic composite material with reflection function and preparation method thereof

The invention discloses a photovoltaic composite material with a reflection function and a preparation method thereof.The photovoltaic composite material comprises a photovoltaic composite film, a supporting bottom plate, supporting frames and an elastic base plate, and the supporting frames facilitating installation of the photovoltaic composite film are welded to the corners of the top of the supporting bottom plate; a photovoltaic composite film with a reflection function is installed on the top of the supporting frame and is composed of an anti-scraping layer, a first PET transparent reflection film, a second PET transparent reflection film and a stress base layer. The top of the first PET transparent reflecting film is adhered with the scratch-resistant layer, and the scratch-resistant layer is made of toughened glass, so that the prepared photovoltaic composite film has a scratch-resistant effect, is dirt-resistant, is not easy to adhere dust and is easy to clean, and the stress base layer is arranged o
