Abstract
The utility model provides an integrated film solid storage battery integrated with a film solar cell. The integrated film solid storage battery comprises a panel, a protective layer and a terminal box, wherein the protective layer is arranged at the front face of the panel and the terminal box is arranged at the back face of the panel; the protective layer, a functional layer and a conductive film layer are overlapped in sequence from bottom to top so as to form a film solar cell; ends of two leading-out leads on the same side are connected with the film solar cell and the other ends of the leading-out leads on the same side are connected with the terminal box. The film solar cell adopts an amorphous silicon film solar cell or a crystalline silicon film solar cell; and the sum of the thicknesses of the protective layer, the functional layer and the conductive film layer is less than 5 microns. After the technical scheme is adopted, the film solar cell is inseparably integrated on the film solid storage battery and is organically combined with the film solid storage battery so that the film solar cell and the film solid storage battery are integrally mounted in a modularized way; therefore, great convenience for mounting and maintenance of the storage battery are obtained, and lower costs of corresponding building-integrated photovolatic products are caused. It can be predicated that integrated combination of the film solid storage battery and the film solar cell is the future technical development tendency.
Description
Technical field
The utility model relates to a kind of integrated film solid accumulator of integrated thin-film solar cell.
Background technology
Solar energy is to use a kind of comparatively widely renewable, clear energy sources, is the eco-friendly power source that generally promote in the whole world.
At present, thin-film solar cells has two kinds on occupation mode.A kind of is to insert electrical network after the polylith connection in series-parallel, becomes the large-sized solar power station; Another kind can provide electric energy to BIPV product (as: solar street light, solar billboard etc.), and it is the independent power supply device that is in from net state.
Described independent power supply device comprises storage battery, monolithic or the some thin-film solar cells that link to each other through lead; Storage battery in this device is indispensable; But itself and thin-film solar cells are separated from each other, are installed separately; This safeguards for this Unit Installation and brings inconvenience, and causes the cost of corresponding BIPV product higher.
In addition, existing storage battery is when temperature is higher than 60 degrees centigrade, and capacity is significantly decayed, and also exist outgas, leak, defective such as explosive under the high temperature.
The utility model content
The utility model technical problem to be solved provides a kind of integrated film solid accumulator of integrated thin-film solar cell convenient for installation and maintenance.
For solving the problems of the technologies described above; The utility model provides a kind of integrated film solid accumulator of integrated thin-film solar cell; It comprises backboard, be arranged on the positive protective layer of backboard, be arranged on the terminal box at the backboard back side; Protective layer, functional layer, conductive film layer are cascading from bottom to top, so that the three forms thin-film solar cells, draw homonymy one end of lead and thin-film solar cells is joined, the homonymy other end and terminal box are joined for two.
For the purpose of the concise description problem, below the integrated film solid accumulator of the said integrated thin-film solar cell of the utility model is all abbreviated as this storage battery.
After adopting above technical scheme; Thin-film solar cells is integrated on the film solid accumulator inseparably; The above two are carried out organic assembling; Make both realize the modularization integral installation, this brings many convenience for the installation and maintenance of this storage battery, and causes the cost of corresponding BIPV product lower.
As everyone knows, the film solid accumulator shows excellent temperature stability.They can be in-40 to 150 degrees centigrade temperature range operate as normal, use very extensively (the high-temperature transducer that comprises semicon industry, oil drilling, space exploration etc.), have great potential.The film solid accumulator shows very high cycle life simultaneously.Use extremely thin negative electrode (0.05 μ m), this battery surpassed for 45000 cycles, 45000 all after dates, and capacity still can keep 95% of former capacity.When using thicker negative electrode, the cycle performance of this battery is still considerably beyond conventional batteries.Use thicker negative electrode (2 μ m), after surpassing the recycling of 2000 cycles, performance still, it has exceeded 2 times of the optimum performances of conventional batteries.
The manufacturer of film solid accumulator is: U.S. Excellatron Solid State LLC. company, details are with reference to http://www.excellatron.com/directions.htm.At home, for the film solid accumulator, chemical engineering institute of University Of Tianjin and China Electronics Technology Group Corporation No.18 Institute's chemistry were all done research with physical power source key lab.
Said thin-film solar cells adopts amorphous silicon thin-film solar cell or crystal silicon thin film solar cell, and the thickness sum of protective layer, functional layer, conductive film layer is less than 5 μ m.
Can predict, the film solid accumulator is used in combination with the integrated of thin-film solar cells, is following technology trends.
Description of drawings
Fig. 1 is the structural representation of this storage battery.
Embodiment
To combine accompanying drawing that the execution mode of the utility model is specifically described below:
Referring to Fig. 1; This storage battery comprises film solid accumulator 1; The depositional fabric form of film solid accumulator 1 is followed successively by from bottom to top: backboard 11, negative current collector 12, negative pole 13, electrolyte 14, positive pole 15, plus plate current-collecting body 16, protective layer 17, the about 0.3 μ m of thickness of negative current collector 12 and negative pole 13.Terminal box 18 is arranged on the back side of backboard 11.Protective layer 17, functional layer 2, conductive film layer 3 are cascading from bottom to top, so that the three forms thin-film solar cells A.Two homonymy one end and thin-film solar cells A that draw lead 4 join, the homonymy other end and terminal box 18 are joined.Thin-film solar cells A adopts amorphous silicon thin-film solar cell or crystal silicon thin film solar cell, and the thickness sum of protective layer 17, functional layer 2, conductive film layer 3 is less than 5 μ m.
Protective layer 17 adopts polymer aluminium foil (heat-insulating material), and because of heat-insulating material can use low temperature manufacturing process, this has reduced the manufacturing cost of this storage battery to a great extent.The preparation of thin-film solar cells A can be adopted conventional pecvd.Also can place charging-discharging controller (not shown in the accompanying drawing) in the terminal box 18, discharge and recharge and off-grid function with control.Charging-discharging controller is the prior art part.
