NOVELTY - A thermal insulation photovoltaic tile comprises flexible thermal insulation substrate (7), flexible photovoltaic cell assembly (8), and flame retardant polymer binder (3). Flexible thermal insulation substrate is covered by flexible waterproof sheet (2) with nanosilica aerogel felt core material (1). Flexible photovoltaic cell assembly includes flexible thin-film battery component (4), film layer (5) and coating layer (6). Flexible waterproof sheet is laminated structure of lower flame retardant polymer cement mortar layer, and glass fiber reinforced flame retardant nonwoven fabric base.    USE - Thermal insulation photovoltaic tile used for solar photovoltaic roof tile.    ADVANTAGE - The tile is waterproof, fire retardant, crack-resistant, crash-resistant, heat insulating, light and flexible.    DETAILED DESCRIPTION - A thermal insulation photovoltaic tile comprises flexible thermal insulation substrate (7), flexible photovoltaic cell assembly (8), and flame retardant polymer binder (3). Flexible thermal insulation substrate is covered by flexible waterproof sheet (2) with nanosilica aerogel felt core material (1). Flexible photovoltaic cell assembly includes flexible thin-film battery component (4), film layer (5) and coating layer (6). Flexible waterproof sheet is laminated structure of lower flame retardant polymer cement mortar layer, high-toughness glass fiber reinforced flame retardant nonwoven fabric base and upper flame retardant polymer cement mortar layer.
