Abstract
The utility model relates to a novel thin -film solar cell subassembly, including substrate layer, front electrode layer, electric layer, back electrode layer, back electrode, last conversion layer and the transparent protection layer who sets gradually from bottom to top, last conversion layer is yb3+ ion and the tm3+ ionic sensitizing agent of having mixed, the back electrode is a printing formula structure, the back electrode layer is the AZO thin layer, front electrode layer is the metal nanowire structure. The conversion layer turns into the short -wavelength light with the long wavelength light through increasing upward, has increased the absorptive light of solar cell, has improved conversion efficiency, through with the back electrode printing on the back electrode layer, improved material utilization rate greatly to save the equipment investment, thereby practiced thrift manufacturing cost.
Description
Technical field
This utility model relates to technical field of solar cell manufacturing, particularly relates to a kind of novel thin film solar module.
Background technology
Solar energy is popular to people as a kind of new forms of energy, and the most various solar products constantly occur, conversion efficiency is more and more higher, the most just include thin-film solar cells.Thin-film solar cells in the market is varied, but more or less has some defects, and on the one hand only with the luminous energy of a certain wave band of sunlight, the light that wavelength is longer or wavelength is shorter all can not be utilized effectively；The fado that does of the most general dorsum electrode layer is to be realized by chemical deposition or physical sputtering, but the equipment price of vacuum coating is expensive, and target utilization is low, and production cost is too high.
Utility model content
The technical problems to be solved in the utility model is to provide the thin-film solar cells that a kind of light that the light of long wavelength can be converted into short wavelength carries out absorbing, and arranges back electrode by printing on dorsum electrode layer simultaneously, is substantially reduced production cost.
For solving above-mentioned technical problem, this utility model relates to a kind of novel thin film solar module, including the substrate layer set gradually from bottom to top, front electrode layer, electric layer, dorsum electrode layer, back electrode, upper conversion layer and protective clear layer；Described upper conversion layer is to be doped with Yb3+ ion and the sensitizer of Tm3+ ion；Described back electrode is printing-type structure；Described dorsum electrode layer is AZO thin layer；Described front electrode layer is metal nano line structure.
As preferred version of the present utility model, described substrate layer is the one in ultra-thin stainless steel, pottery or glass.
As preferred version of the present utility model, described dorsum electrode layer is aluminum film layer or nickel thin layer.
As preferred version of the present utility model, described protective clear layer is convex lens glassy layer.
The beneficial effects of the utility model are: by increasing upper conversion layer, long wavelength light is converted into short-wavelength light, adds the light that solaode absorbs, improve transformation efficiency；Assembled by the light becoming the protective clear layer of lens-shaped to make to be radiated at thin-film solar cells, thus reduce dissipating of light, improve absorbance；By back electrode is printed on dorsum electrode layer, substantially increases stock utilization, and save equipment investment, thus saved production cost.

Description of reference numerals
1-substrate layer, electrode layer before 2-, 3-electric layer, 4-dorsum electrode layer, the upper conversion layer of 5-, 6-noctilucence bisque, 7-protective clear layer.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.It should be noted that the word "front", "rear" used in describing below, "left", "right", "up" and "down" refer to the direction in accompanying drawing, word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center.
Seeing Fig. 1, this utility model relates to a kind of novel thin film solar module, including the substrate layer 1 set gradually from bottom to top, front electrode layer 2, electric layer 3, dorsum electrode layer 4, back electrode 5, upper conversion layer 6 and protective clear layer 7.
Substrate layer 1 is the one in ultra-thin stainless steel, pottery or glass.One layer of Ag films layer can be coated on electric layer 3, increase light transmittance and conductivity.Front electrode layer 2 is metal nano line structure, can make nano silver wire or copper nano-wire.
Dorsum electrode layer 4 is AZO thin layer.By back electrode 5 is printed on dorsum electrode layer 4, substantially increases stock utilization, and save equipment investment, thus saved production cost.
Upper conversion layer 6 is for being doped with Yb3+
Ion and the sensitizer of Tm3+ ion.By increasing upper conversion layer 6, long wavelength light is converted into short-wavelength light, adds the light that solaode absorbs, improve transformation efficiency.
Protective clear layer 7 is convex lens glassy layer, the light being radiated at thin-film solar cells can be made to assemble, thus reduce dissipating of light, improve absorbance.
It is above better embodiment of the present utility model, but protection domain of the present utility model is not limited to this.Any those of ordinary skill in the art in the technical scope disclosed by this utility model, the conversion expected without creative work or replacement, all should contain within protection domain of the present utility model.Protection domain the most of the present utility model should be as the criterion with the protection domain that claim is limited.
