Abstract

The invention discloses a thermal-insulation photovoltaic tile. The thermal-insulation photovoltaic tile is characterized by being composed of a flexible thermal-insulation substrate and a flexible photovoltaic cell component which is bound on the flexible thermal-insulation substrate through an inflaming retardant polymer binder. The flexible thermal-insulation substrate is a nano silicon dioxide aerogel felt core material with two sides covered with flexible water-proof sheets. The flexible photovoltaic cell component comprises a flexible thin-film cell component, a film layer and a coating layer from the interior to the exterior successively. The flexible water-proof sheets are in layer structures, and each comprises a lower inflaming retardant polymer cement mortar layer, a high-tenacity glass fiber reinforced inflaming retardant non-woven fabric padding and an upper inflaming retardant polymer cement mortar layer from the bottom to the top successively, and the three layers of structures are integrally consolidated. According to the thermal-insulation photovoltaic tile, the flexible substrate which is water proof and impervious, fire proof and inflaming retardant, anti-crack and impact resistant, thermal insulating and light and thin is combined with the amorphous silicon flexible thin-film solar photovoltaic cell component to form the photovoltaic roof tile which can be fire proof and water proof and thermal insulation and can perform photovoltaic power generation.

Description

technical field [0001] The invention relates to the field of photovoltaic building integration and photovoltaic building materials, in particular to a flexible thermal insulation photovoltaic tile that can be widely used in green buildings with energy saving and self-generated electricity, which has fire protection, waterproof, thermal insulation, Enhance crack resistance, roof decoration and photovoltaic power generation and other multiple use functions, and apply to photovoltaic buildings for new construction and energy-saving renovation of existing buildings, so as to realize high-efficiency energy-saving buildings and self-consumption of electricity.
