A method is described for recycling photovoltaic panels of the type comprising a glass attached to a plurality of photovoltaic cells by means of an insulating junction plate, wherein the photovoltaic cells comprise silicon elements and metallic contacts. The method comprises detaching the glass from the photovoltaic cells and subsequently separating the glass from the photovoltaic cells by means of an air flow. In detail, to separate the glass from the photovoltaic cells, the glass and the photovoltaic cells are dropped from a falling point and, during their fall, glass and photovoltaic cells are impinged with an air flow that is directed along a substantially horizontal direction and which is such to obtain a separation of the falling paths of the glass and of the silicon elements sufficient to drop them into a glass collecting element and a silicon collecting element respectively, placed below the falling point. A plant adapted to implement the method is also described.

Abstract

A method is described for recycling photovoltaic panels of the type comprising a glass attached to a plurality of photovoltaic cells by means of an insulating junction plate, wherein the photovoltaic cells comprise silicon elements and metallic contacts. The method comprises detaching the glass from the photovoltaic cells and subsequently separating the glass from the photovoltaic cells by means of an air flow. In detail, to separate the glass from the photovoltaic cells, the glass and the photovoltaic cells are dropped from a falling point and, during their fall, glass and photovoltaic cells are impinged with an air flow that is directed along a substantially horizontal direction and which is such to obtain a separation of the falling paths of the glass and of the silicon elements sufficient to drop them into a glass collecting element and a silicon collecting element respectively, placed below the falling point. A plant adapted to implement the method is also described.
