Photovoltaic tile on roof and manufacturing method thereof

Abstract

The invention discloses a photovoltaic tile on a roof and a manufacturing method of the photovoltaic tile on the roof, wherein the photovoltaic tile on the roof integrates the functions of fire prevention, water prevention, decoration and photovoltaic power generation. The photovoltaic tile on the roof comprises a roof tile base material and a photovoltaic decorative layer, wherein the photovoltaic decorative layer and the curved surface of the roof tile base material are bonded into a whole through adhesion agents; the roof tile base material is a clay tile or a ceramic tile or a metal tile or a glass tile or a cement tile; the roof tile base material is coated with high molecular adhesion agents; the photovoltaic decorative layer sequentially comprises a flexible thin film batter assembly, a film layer and a coating layer from interior to exterior. As non-crystalline silicon and other flexible solar photovoltaic thin film batteries are bonded to the surfaces, with the waving feeling, of the ceramic tile, the clay tile, the glass tile and the like through high molecular polymer glue, photovoltaic tiles on roofs which have various complex models, can achieve the function of the photovoltaic power generation and can also keep the shape and color of the tiles on the building roofs can be produced in a factory.

Description

technical field [0001] The invention relates to the field of photovoltaic building integration and photovoltaic building materials, in particular to a roof photovoltaic tile integrating multiple functions of fire prevention, waterproof, decoration and photovoltaic power generation and a preparation method thereof. Background technique [0002] Building-integrated photovoltaics (BIPV) is becoming the most promising application field of photovoltaic technology. Because building roofs have ideal lighting surfaces and can be used for installing photovoltaic products, they have become the first choice for the promotion and application of building-integrated photovoltaics. The United States, the European Union, Japan and other developed countries have successively launched the solar golden roof plan. The Chinese government also regards roof power generation as the driving force of the photovoltaic application market and has introduced a series of policies to vigorously promote it. ...
