Technical field
The present invention relates to a kind of high-efficiency solar-powered photovoltaic plate.
Background technology
Solar energy power generating is a kind of new-generation technology utilizing the photovoltaic effect of interface and solar radiation directly can be converted to electric energy.It is predicted, solar energy power generating can occupy the important seat of world energy sources consumption in 21 century, not only wants Substitute For Partial conventional energy resource, and will become the main body of world energy supplies.Expect the year two thousand thirty, regenerative resource will account for more than 30% in total energy structure, and the accounting of solar energy power generating in world's total electricity supply also will reach more than 10%; To the year two thousand forty, regenerative resource will account for more than 50% of total energy consumption, and solar energy power generating will account for more than 20% of total electricity; To 21 century Mo, regenerative resource will account for more than 80% in energy resource structure, and solar power generation will account for more than 60%.These numerals be enough to demonstrate solar photovoltaic industry development prospect and in the important strategic position of energy field.
The key element of solar photovoltaic technology is solar battery sheet, and solar battery sheet carries out packaging protection after series connection can form large-area solar module, then coordinates the parts such as upper power controller just to define solar energy photovoltaic generator.The solar panel be made up of one or more solar battery sheet is called solar energy photovoltaic panel, photovoltaic panel assembly is that a kind of exposure in the sun just can thermal-arrest, be galvanic Blast Furnace Top Gas Recovery Turbine Unit (TRT) by transform light energy, be made up of the thin body solid photovoltaic cell almost all made with semiconductor material (such as monocrystalline silicon, polysilicon etc.).Photoelectric conversion efficiency is the key factor of assessment solar cell quality, and photoelectric conversion efficiency temperature influence is very large, and temperature is higher, and photoelectric conversion efficiency is lower.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provide a kind of structure simple, be easy to the high-efficiency solar-powered photovoltaic plate produced, photoelectric conversion efficiency is high.
The technical solution adopted in the present invention is: the present invention includes photovoltaic panel body, and the top of described photovoltaic panel body is provided with high light transmittance ratio glass plate, and the surface of described high light transmittance ratio glass plate is covered with long wave wave filtering layer.
Described long wave wave filtering layer is filtering coating.
Or described long wave wave filtering layer is filtering film.
Described long wave wave filtering layer is positioned at the upper surface of described high light transmittance ratio glass plate.
Or described long wave wave filtering layer is positioned at the lower surface of described high light transmittance ratio glass plate.
Or described long wave wave filtering layer is positioned at upper surface and the lower surface of described high light transmittance ratio glass plate.
The invention has the beneficial effects as follows: because the top of photovoltaic panel body of the present invention is provided with high light transmittance ratio glass plate, the surface of described high light transmittance ratio glass plate is covered with long wave wave filtering layer; The present invention is by arranging described high light transmittance ratio glass plate, make sunlight transmitance high, be unlikely to because the existence of glass plate significantly reduces the absorption of luminous energy, by arranging long wave wave filtering layer, the long waves such as the infrared ray in solar spectral are filtered, avoid long wave to be produced heat by described photovoltaic panel bulk absorption to elevate the temperature, thus significantly reduce the temperature of described photovoltaic panel body, and then raising photoelectric conversion efficiency, therefore structure of the present invention simple, be easy to produce, photoelectric conversion efficiency is high, is a kind of high-efficiency solar-powered photovoltaic plate.
