And the znO film is a neotype broad stopband compound semiconductor material, and the raw materials is cheaply easy, has higher fusing point, exciton binding energy and good electromechanical coupling nature and lower electron moreover and lures living defect.
Description
Technical field
The utility model belongs to solar cell preparation field, particularly relates to a kind of solar panel.
Background technology
Solar panel traditional is at present by Monocrystalline silicon cell piece, or polycrystalline silicon battery plate, and ultrawhite toughened glass, these material layers, through solar panels laminating machine high temperature lamination, force together and form by TPT, EVA.Solar energy layer pressing plate is under sunlight, and absorb sunlight, be translated into electric energy and be used for rechargeable battery or solar product, or be connected with electrical network, electricity is existed in electrical network, evening on daytime can provide electric power for user.
But traditional solar panel adopts white toughened glass as component lamination when lamination, then in use Al-alloy metal frame packaging, its quality is very large, is inconvenient to carry and move.The cell panel that these shortcomings make have received very large restriction in use.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rubber that adopts to replace thick and heavy toughened glass, the high efficiency solar panel that lamination is prepared.
The utility model realizes like this, a kind of solar panel, comprise the transparent rubber layer, an EVA layer, cell piece, the 2nd EVA layer and the backboard that stack gradually by being laminated together to form complex, wherein, cell piece comprises ZnO/Al composite back electrode, the first transparent conductive film, N-type Nano silicon-crystal thin film, intrinsic undoped Nano silicon-crystal thin film as intermediate layer, P type Nano silicon-crystal thin film, the second transparent conductive film, insulating layer of thin-film and polyimide flex substrate successively from upper lower floor.
Further, the first transparent conductive film and the second transparent conductive film are ZnO transparent conductive thin film.
Further, the outer surface of transparent rubber layer has Semi-cylindrical hil ls.
Further, described insulating layer of thin-film is diamond thin.
Compared with prior art, beneficial effect is the utility model: the present invention adopts ZnO-based transparent conductive film material as the Si based solar battery sheet of electrode, and adopt rubber to replace thick and heavy toughened glass, lamination prepares high efficiency solar panel.And ZnO film is a kind of novel wide bandgap compound semiconductor material, raw material is easy to get cheapness, and there is higher fusing point, exciton bind energy and good mechanical-electric coupling and lower electronics induced defects, in addition, the epitaxial growth temperature of film is lower, be conducive to reducing equipment cost, suppress solid phase outdiffusion, improve film quality, also be easy to realize doping, wherein substitute traditional aluminium electrode by ZnO/Al composite back electrode and light absorption can be made to strengthen, thus increase short circuit current, improve the transformation efficiency of solar cell, improve the stability of battery.
