The utility model relates to a bill -board is instructed to photovoltaic, include by the last colored thin film photovoltaic subassembly that down sets up, cold light piece, backplate glass and connect photovoltaic terminal box, charge controllers, the cold light piece power converter in the photovoltaic module side, colored thin film photovoltaic subassembly is colored PVB layer, transparent PVB layer that stacks gradually and the power chip layer that is equipped with the fretwork pattern. The photovoltaic terminal box links to each other with charge controllers, and charge controllers links to each other with cold light piece power converter, and cold light piece power converter then links to each other with the cold light piece, colored thin film photovoltaic subassembly, cold light piece and the backplate glass lamination of from top to bottom closely laminating. Colored thin film photovoltaic subassembly can also pass through the sticky subsides of structure with backplate glass's both ends, can form hollow layer. The utility model discloses combine together sun photovoltaic module and bill -board, solved the problem of throwing light on at night of outdoor advertising tablet from far -off regions, more practiced thrift the consumption of resource, have higher practical value and spreading value.
