Description
Technical Field
The utility model relates to a double-sided photovoltaic cell assembly with double glass.
Background
With the continuous development of new energy technology, photovoltaic power generation is widely applied. Solar power generation is to directly convert solar energy into electric energy by using a battery assembly, and the generated energy of a single battery is very limited due to technical and material reasons, and the solar battery in practical use is a battery system formed by connecting single batteries in series and parallel, which is called a battery assembly (array). A single cell is a silicon transistor diode, which, depending on the electronic properties of the semiconductor material, when solar light impinges on a P-N junction made of a homogeneous semiconductor material of two different conductivity types, P-type and N-type, under certain conditions solar radiation is absorbed by the semiconductor material, creating unbalanced carriers, i.e. electrons and holes, in the conduction and valence bands. The potential barrier region has a strong built-in electrostatic field similar to that of the P-N junction, so that the current density J, the short-circuit current Isc and the open-circuit voltage Uoc can be formed under illumination. If electrodes are led out from two side surfaces of the built-in electric field and connected with a load, in theory, a loop formed by a P-N junction, a connecting circuit and the load has 'photo-generated current' flowing through, and the solar cell module realizes the power P output to the load.
Existing battery packs can be basically divided into: crystalline silicon cell plate: a polycrystalline silicon solar cell, a monocrystalline silicon solar cell; amorphous silicon cell panel: thin film solar cells, organic solar cells; chemical dye cell plate: dye sensitized solar cells. The photoelectric conversion efficiency of the single crystal silicon solar cell is about 15% and up to 24% at the highest, which is the highest photoelectric conversion efficiency among all kinds of solar cells, but the manufacturing cost is so great that it cannot be used generally yet. The manufacturing process of the polysilicon solar cell is almost similar to that of the monocrystalline silicon solar cell, but the photoelectric conversion efficiency of the polysilicon solar cell is reduced to about 12% (the highest worldwide efficiency polysilicon solar cell with 14.8% of the current summer and the current summer of 7 months of 2004). The amorphous silicon solar cell is a novel film solar cell which appears in 1976, is completely different from the manufacturing method of monocrystalline silicon and polycrystalline silicon solar cells, greatly simplifies the process, consumes little silicon material and has lower electricity consumption, and the amorphous silicon solar cell has the main advantages of generating electricity under the condition of weak light. However, the amorphous silicon solar cell has a main problem that the photoelectric conversion efficiency is low, the international advanced level is about 10%, and the amorphous silicon solar cell is not stable enough, and the conversion efficiency is attenuated with the extension of time.
All current battery packs are essentially: packaged together by silicon chip series or parallel combination. Consists of a transparent top surface, a colloid sealing material, a silicon wafer connecting group, a back layer and an external frame. The photoelectric conversion efficiency of the photovoltaic cell panel with the packaging structure is generally about 15%, and the high photovoltaic cell panel can only reach about 16.5%. In addition, for the double-sided solar cell module packaged by double glass, the light of the cell gap cannot be utilized, and the power loss in the process of packaging the module from the cell is large, so that the double-sided photovoltaic cell module with double glass has been generated.
