Description
Technical field
The utility model belongs to technical field of photovoltaic power generation, is specifically related to a kind of high-efficiency self-cleaning Graphene coating solar-energy photovoltaic module.
Background technology
photovoltaic panel assemblythat a kind of exposure just can produce in the sun
direct currentblast Furnace Top Gas Recovery Turbine Unit (TRT), by almost all with the thin body solid that semiconductor material (such as silicon) is made
photovoltaic cellcomposition.Owing to there is no movable part, therefore can long-time operation and can not cause any
loss.Simple photovoltaic cell can be wrist-watch and calculator provides the energy, and more complicated photovoltaic system can be house and provides illumination, and is mains supply.Photovoltaic panel assembly can make difformity, and assembly can connect, to produce more electric power.Balcony and building surface all can use photovoltaic panel assembly, and be even used as a part for window, skylight or masking device, these photovoltaic facilities are commonly called the photovoltaic system being attached to building.
