Description

Be used to intercept the thin-film solar cells composition structure of infrared light
Technical field
The utility model relates to a kind of thin-film solar cells composition structure that is used to intercept infrared light, refers to a kind of effective obstruct infrared light especially and has the thin-film solar cells composition structure of high conductivity.
Background technology
Grow up because of the global solar market demand, when the river rises the boat goes up to cause silicon starving, silicon wafer solar cell and module production cost.And advantages such as thin-film solar cells is frivolous because of having, low-cost, deflection, various appearances design become after the silicon wafer solar cell, are considered to the most potential current heliotechnics.
The technology of solar power generation mainly is divided into silicon metal (Wafer base) and film (Thin Film base) solar cell two big classes according to the manufacturing process differentiation.Wherein because of silicon has advantages such as avirulence, oxide are stable, add that the existing mature and stable industrial treatment technology of industrial circle handles silicon materials, therefore, the silicon wafer solar cell is the existing market application mainstream, accounts for the world market and reaches ninety percent approximately.
Yet, since in recent years states such as Germany, Spain under the solar boosted policy implication, powerful the raising of the solar cell module market demand, 2007, the demand of solar cell module heated, once cause the silicon raw material seriously the short supply, price skyrockets.Though since 2008 second half year, left successively because of polysilicon manufacturer production capacity, add that the market demand eases up, impel the silicon cost of material to downgrade gradually, the unsettled experience of silicon cost of material has allowed solar energy manufacturer realize the importance of scattered risks more; Moreover the silicon wafer solar energy industry is low because of equipment and manufacturing process technology maturation, entry threshold, and in numerous competitors' industry, the high gross profit epoch in the past have been difficult to see again, impels solar energy manufacturer to quicken to research and develop feeler turning film area of solar cell.
Thin-film solar cells as its name suggests, is to form to produce photoelectric film on plastic cement, glass or metal substrate, and thickness only needs number μ m, therefore can significantly reduce the consumption of raw material under same light-receiving area than the Silicon Wafer solar cell.Thin-film solar cells is not to be the product of new ideas, in fact, artificial satellite generally adopted the high conversion efficiency thin-film solar cell panel made with GaAs (GaAs) (with monocrystalline silicon as substrate already in the past, conversion usefulness can reach more than 30%) generate electricity, but its cost costliness, be used to the too industry of navigating more, can't popularize now.So present industry main flow adopts amorphous silicon (a-Si) to make the light absorbing zone of thin-film solar cells (being semiconductor layer) more.Thin-film solar cells can be made on cheap glass, plastic cement or stainless steel substrate in a large number, to produce large-area solar cell, and its manufacturing process more can directly import quite ripe TFT-LCD manufacturing process, this is one of its advantage, so industry falls over each other to drop into the research in this field invariably.
Basically, the solar cell manufacturing process of the relative other types of thin-film solar cells is comparatively simple, has that cost is low, the mass producible advantage.With regard to the composition of thin-film solar cell substrate, its basic manufacturing process can be through three layers of deposition (deposition), three road laser scribing (scribe) formalities, as described below: at first, on the glass substrate of subscribing size, plate layer of transparent conductive film (Transparent Conductive Oxide with physical gas-phase deposition (PVD) earlier, TCO), it selects light transmission height and the good material of conductivity, as tin indium oxide (ITO), tin oxide (SnO2) or zinc oxide (ZnO) etc.Then with its preceding electrode pattern (patterning) of infrared laser line definition.So far be first road deposition and line formality.Second stage is the making of main absorbed layer (Active layer), it is generally with plasma-assisted chemical vapour deposition (PlasmaEnhanced Chemical Vapor Deposition, PECVD) technology grows the hydrogenated amorphous silicon structure (p-a-Si:H/i-a-Si:H/n-a-Si:H) of one deck p-i-n type arrangement on electrode surface, and this main absorbed layer is with the agent structure of p-n semiconductor junction (p-n junction) as light absorption and power conversion.Can carry out the laser scribing step equally after this step, be the main absorbed layer define pattern of producing, so far be second road deposition and line formality.Form the back electrode (back contact) of aluminium/silver-colored material at last again based on sputter (sputter) technology thereon, and carry out the 3rd road laser scribing and define its back electrode figure.
So because of using transparency conducting layer in the transparency of visible region, the semiconductor of selected transparency conducting layer must be the semiconductor of wide energy gap, so select for use the energy gap width must be greater than the semiconductor of the transparency conducting layer of visible light energy scope, so increased the integral thickness of thin-film solar cells, and for increasing the conduction property of transparency conducting layer, general mode by the doping trace impurity, promote its conductivity, so technology comparatively bothers, therefore, how effectively to intercept infrared light reaching energy-saving effect, and how to reduce the thin film solar integral thickness and how to improve light transmittance and the efficient of absorptivity and opto-electronic conversion, industry is needed the problem of solution badly for this reason.
