Abstract
A TCO (Transparent Conducting Oxide) glass structure with improved light transmissibility aims to technically improve the visible light transmissibility of TCO glass, increase light energy projected on a solar cell film and improve the conversion efficiency of a solar cell. The TCO glass structure comprises a glass substrate and a transparent conductive film layer on the glass substrate, and has the key points that a lattice structure formed by burr distribution is arranged on one end surface of the glass substrate, and the transparent conductive film layer is positioned on the side of the glass substrate with burrs.

Therefore, the TCO glass structure provided by the utility model has better spectral transmissibility and haze.
Description
Technical field
The utility model belongs to the solar cell preparing technical field, relates to a kind of novel TCO glass, and this TCO glass is made up of with the glass substrate and the transparent conductive film layer of circular burr a surface, and what transparent conductive film layer was positioned at base plate glass has a burr side.
Background technology
At present; Because the exploration amount of world's energy capable of using such as coal, oil etc. reduces significantly; How to find available new forms of energy to become the problem of World Focusing; And solar energy is pollution-free and inexhaustible as a kind of novel energy, and that uses becomes the focus energy of paying close attention to the most at present not to the utmost.Solar power generation has a lot of advantages, and as safe and reliable, the construction period is short, and easy maintenance can unattended operation etc., and disclosed solar photovoltaic conversion is the battery sheet of the solar module that relies on.Because amorphous silicon can absorb more light intensity than crystal silicon, so the amorphous silicon battery assembly becomes the focus of present research.The TCO transparent conductive film is applied in amorphous silicon battery film field widely owing to have good electrical conductivity and high visible light transmissivity.
Though the TCO transparent conductive film has good electrical conductivity and high visible light transmissivity; But some light is absorbed or reflection by glass; In order to improve the photoelectric conversion efficiency that increases battery that sees through of light, we can reach the purpose that reduces the light reflection through the light path that increases light transmission glass.
Summary of the invention
The purpose of the utility model is in order to improve the visible light transmissivity of TCO glass; Improve and be incident upon the light energy on the solar cell rete; Improve the technical problem of conversion efficiency of solar cell; Designed a kind of structure that improves the TCO glass of light transmission rate, increased the light path of light transmission glass through burr is set on glass substrate, and then improve light transmission rate.
The utility model for realizing the technical scheme that goal of the invention adopts is; A kind of structure that improves the TCO glass of light transmission rate; Comprise glass substrate and the transparent conductive film layer on glass substrate; Key is: an end face of described glass substrate is provided with the lattice structure that distributes and form with burr, and transparent conductive film layer is positioned at a side that has burr.
The utility model has the advantages that: compare with conventional TCO glass manufacture craft, saved TCO film top layer etching process, simplified the making technology process, saved production cost.Therefore the design does not need etching in process of production, has reduced environmental pollution and to the injury of the person.The surface promptly has hemispherical dome structure after film forming, compares with " pyramid " type of the prior art and conical face, has better spectral transmittance and mist degree.What conventional TCO glass adopted is the base plate glass on plane, and the surface is very smooth, and in the film forming incipient stage, nucleus forms relatively difficulty.The design's base plate glass adopts the glass of surface band burr as substrate, and surface roughness is big, forms a lot of ledge structures, for TCO rete nucleus forms the condition of providing convenience, therefore, can under lower process temperatures, carry out.
Below in conjunction with accompanying drawing the utility model is elaborated.
