The utility model is that the technical scheme that its technical problem of solution adopts is: a kind of thin-film solar cells, comprise substrate, described substrate is provided with front electrode layer, described front electrode layer is provided with electric layer, described electric layer is provided with transparent dorsum electrode layer, it is characterized in that: between described electric layer and transparent dorsum electrode layer, be provided with silver-colored thin layer, described transparent dorsum electrode layer is provided with conversion layer, described upper conversion layer is provided with glassy layer, and described glassy layer becomes lens-shaped.
As further improvement of the utility model, described glassy layer thickness is 30nm.
As further improvement of the utility model, the thickness of described silver-colored thin layer is 12nm, and its optical transmittance is greater than 80%, and square resistance is less than every square 6 Ω.
As further improvement of the utility model, described upper conversion layer is the Yb that adulterated
3+ion and Tm
3+the sensitizer of ion.
As further improvement of the utility model, described substrate is ultra-thin stainless steel.
As further improvement of the utility model, described transparent dorsum electrode layer is aluminum film layer.
The beneficial effects of the utility model are: the utility model is by increasing the more silver-colored thin layer of high permeability, more excellent electric conductivity, the electric conductivity of thin-film solar cells is improved greatly, by increasing upper conversion layer, long wavelength light is converted into short-wavelength light, increased the light that solar cell absorbs, improved transformation efficiency, by becoming the glassy layer of lens-shaped that the light that is radiated at thin-film solar cells is assembled, thereby reduce dispersing of light, improved absorptivity.
Accompanying drawing explanation

Described glassy layer 7 thickness are 30nm.
The thickness of described silver-colored thin layer 4 is 12nm, and its optical transmittance is greater than 80%, and square resistance is less than every square 6 Ω, and described silver-colored thin layer 4 optical transmittances are 90%, and square resistance is every square 4 Ω.
Described upper conversion layer 6 is the Yb that adulterated
3+ion and Tm
3+the sensitizer of ion.These two kinds of ion dopings, in sensitizer, can make Tm
3+the Up-conversion Intensity of ion improves 3 more than the order of magnitude.
Described substrate 1 is ultra-thin stainless steel.Also can be pottery, glass etc.
Described transparent dorsum electrode layer 5 is aluminum film layer.Also can be nickel thin layer.
Above-described embodiment is preferably execution mode of the utility model; but execution mode of the present utility model is not subject to the restriction of embodiment; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify and all should be equivalent substitute mode, within being included in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claim was defined.
