Definitions
- the invention relates to a carrier body for solar cells.
- a solar cell is understood to mean a photovoltaic cell.
- the invention has for its object to improve a carrier body for solar cells so that the thermal resistance of the connection between the solar cell and the carrier body or a heat sink is significantly reduced.
- the carrier body consists of a ceramic material with sintered Metallmaschines Siemensen, on the carrier body at least one solar cell soldered or sintered and electrically connected to the metallization and the carrier body has ceramic cooling elements.
- the thermal resistance is significantly improved, the solar cells are sufficiently cooled, improves the efficiency and extends the life.
- Carrier body made of a ceramic material with sintered metallization rapidly dissipate heat and distribute it in the carrier body. The cooling elements of the carrier body ultimately dissipate the heat to the environment.
- the support body may have a three-dimensional structure as cooling elements that produce the largest possible surface, such as fins for air cooling or the cooling elements are closed inner channels or chambers with supply ports for externally supplied cooling with gas or liquid.
- the inner channels and chambers have the largest possible surface area. It can be done either a cooling with a gas, in particular an air cooling, or cooling with liquids.
- the carrier body is plate-shaped and thus has an upper side, a lower side and side surfaces, wherein sintered metallization regions are arranged both on the upper side and on the lower side and are electrically connected via sintered metallization regions on the side surfaces and at the corners.
- the connection of the metallization from top to bottom can also be done by one or more via holes (vias).
- one or more solar cells are soldered onto one of the upper and lower sides and electrical or electronic control elements for the at least one solar cell are soldered onto the metallizations on the respective other upper and lower side. This separation of the solar cells from the electrical or electronic controls has the advantage that the electrical or electronic controls are decoupled from the heat of the solar cells, i. are not exposed to increased heat load.
- the ceramic material is preferably Al 2 O 3, MgO, SiO 2, mixed oxide ceramics, or nitride ceramics such as AIN, Si 3 N 4.
- An inventive method for producing a carrier body according to any one of claims 1 to 5 is characterized in that the Carrier body is made with inner channels or chambers and forms a cooling unit and printed by screen, pad or stencil printing process with AgPt paste and baked and then a solar cell on its back side electroplated with Ag and then cooling unit and solar cell by, for example, an interposed Lotfolie be connected.
- Another inventive method for producing a carrier body according to any one of claims 1 to 5 is characterized in that the carrier body is manufactured with inner channels or chambers and forms a cooling unit and printed by screen, pad or stencil printing process with AgPt paste and baked and a solar cell is degreased and a paste with the finest silver particles is screen printed on the cooling unit and then the solar cell is laid and a solid metallic composite is produced.
- Solar cells are soldered or sintered onto the sintered metallization regions of the ceramic carrier body.
- the heat sinks connected to the carrier body may be simple ceramic substrates, they may have a three-dimensional structure (eg fins) or they may also have closed channels or chambers (with supply connections) to the outside.
- the cooling itself can be done by a gas or a liquid.
- Metallizations can be filled and cured coatings, the usual thick film metallizations such as tungsten, molybdenum, silver, silver-palladium, silver-platinum, etc., but also AMB or DCB composites.
- the heat sinks may be made of the usual ceramics such as Al 2 O 3, MgO, SiO 2, mixed oxide ceramics, or nitride ceramics such as AlN, Si 3 N 4 be prepared.
- the molding can be by film casting, extrusion, dry pressing, injection molding, hot casting, die casting, additive or generative shaping (3D printing) directly or by mechanical processing of blankets of ceramic materials or unsintered moldings (green compacts), which are subsequently sintered in the required shape to be brought.
- a cooling unit made of AIN is screen printed with AgPt paste and baked.
- a solar cell is galvanically coated with Ag on the rear side. At approx. 265 ° C, the cooling unit and the solar cell are connected by a solder foil placed between them.
- a cooling unit made of AIN is screen printed with AgPt paste and baked at approx. 860 ° C.
- a solar cell is degreased. Then a paste with the finest silver particles is screen-printed on the cooling unit. The solar cell is placed on top and at about 400 ° C with access of air a solid metallic composite is produced.
- FIG. 1 shows an embodiment according to the invention of a carrier body 1 made of a ceramic material.
- the carrier body 1 has an upper side 5, a lower side 6 and side surfaces 7.
- the reference numeral 3 are denoted by the carrier body 1 sintered metallization, forming a circuit board.
- these metallization regions 3 are arranged on the upper side 5 as well as on the underside 6 and the side surfaces 7 and the corners 8.
- Solar cells 2 are arranged only on the top 5.
- Figure 1 is not to scale.
- cooling channels arranged, which are connected to the supply terminals 4. Cooling fluid is conducted into the carrier body 1 via these supply ports 4, which cools the carrier body.
- the metallization areas 3 5 solar cells 2 are soldered here only on the top.
