Abstract
The utility model provides a combined type thin -film solar cell, glass roof and glass bottom plate including parallel arrangement, the glass roof with be provided with the combined type thin layer between the glass bottom plate, the combined type thin layer is including locating the magnesium alloy of glass bottom plate upper surface heat dissipation layer, locate the EVA layer of magnesium alloy heat dissipation layer upper surface and locating the electricity generation based bulk layer of EVA layer upper surface. Choose magnesium alloy conduct heat dissipation layer for use, better spread the heat of ability has effectively avoided the local temperature too high, and the magnesium alloy has good reflection of light effect in addition to effectively reduce the hot spot effect, makeed solar cell's life obviously prolong. So this combined type thin -film solar cell has design science, effective advantage of dispelling the heat, effectively reducing the hot spot effect.
Description
Technical field
The utility model relates to a kind of solar cell, specifically, relate to a kind of composite film solar cell of effective reduction hot spot effect.
Background technology
Solar cell is the device directly light energy conversion being become electric energy by photoelectric effect or Photochemical effects.There is hot spot effect in current solar cell, hot spot effect refers in the application: under certain condition, the solar module of crested in a series arm, will be taken as other energy having the solar module of illumination to produce of load consumption.The solar module of crested now can generate heat, Here it is hot spot effect, the destruction solar cell that this effect can be serious.Have the portion of energy that the solar cell of illumination produces, the battery of all possibility cresteds consumed.Use in solar cell in reality, the solder joint on battery component will be made to melt and damage grid line if the temperature that hot spot effect produces has exceeded certain limit, thus causing scrapping of whole solar module, hot spot effect makes at least reduce 10% the actual life of solar module.Although all will consider the impact of shade when solar module is installed, and add and join protective device to reduce the impact of hot spot, hot spot phenomenon is inevitable.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus provides the composite film solar cell of a kind of design science, efficiently radiates heat, effectively reduction hot spot effect.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of composite film solar cell, comprise the glass top plate and glass film plates that be arranged in parallel, be provided with composite film layer between described glass top plate and described glass film plates, described composite film layer comprises the magnesium alloy heat radiation layer being located at described glass film plates upper surface, the EVA layer being located at described magnesium alloy heat radiation layer upper surface and is located at the generating body layer of described EVA layer upper surface.Wherein, " EVA " in the utility model refers to that EVA is ethylene-vinyl acetate copolymer.
Based on above-mentioned, described magnesium alloy heat radiation layer is provided with electric current both positive and negative polarity output.
The utility model hinge structure has substantive distinguishing features and progress, specifically, the conductive coefficient of the magnesium alloy materials of the described magnesium alloy heat radiation layer in described composite film solar cell is lower, be not easy to assemble the heat in solar cell, easily heat diffusion gone out, effectively avoid the local temperature of solar cell too high, magnesium alloy heat radiation layer has good reflection action in addition, thus effectively reduce hot spot effect, the useful life of solar cell is obviously extended.Therefore, described composite film solar cell has the advantage of design science, efficiently radiates heat, effectively reduction hot spot effect.
