Description
Technical field
The invention belongs to the solar cell field of new, particularly a kind of crystal silicon solar batteries front electrode forms with lead-free silver electrocondution slurry and preparation method thereof.
Background technology
Crystal silicon solar batteries is a kind of semipermanent physical battery that solar energy is converted into electric energy; Along with fossil (oil; Coal; Natural gas etc.) the extreme consumption of the energy, the lack of energy of generation and serious day by day greenhouse effect, human demand to novel clean energy resource becomes more and more urgent.In very long time in future; The sun will be effective supplier of human clean energy resource; At present, crystal silicon solar batteries is to be one of domestic energy active parts with conversion of solar energy, and its range of application just expands to daily life from space flight, military affairs; When not producing new pollution, the reduction of cost will make solar cell obtain using more widely.
Common screen printing crystalline silicon solar cell is divided into two kinds of monocrystalline silicon and polysilicons, and except minority N type crystalline silicon battery, main product is a P type battery.General manufacture craft is following: the silicon chip of buying from producer that is mixed with boron; At first remove the lattice damage part that causes because of slicing processes through cleaning and removing; Form the matte structure of low surface reflectivity; Form 0.2-0.5 μ m dark phosphorus heavily doped region as diffuse source at silicon chip surface with POCl3 then, be referred to as emitter (emitter), emitter and P mold base joint form the P/N knot; Pass through plasma enhanced vapor deposition (PECVD) in emitter surface in addition, form the SiN of the about 80nm of thickness on the surface
X(silicon nitride) antireflection film stamps aluminum conductive electric slurry and conductive silver slurry (back of the body silver) at the cell back face then, behind sintering, can form the back of the body (BSF) and welding zone electrode, at positive SiN
XLast printing front side silver paste material (positive silver) forms gate line electrode (finger) and main electrode (busbar) realization collected current and the welding zone electrode is provided through sintering.
Front side silver paste will burn the SiN of (fire through) insulation in sintering process
X(silicon nitride) antireflection rete forms ohmic contact with silicon substrate.Good Ohmic contact shows two aspects, one of which, alap contact resistance, its two, do not produce the phenomenon of burning that impurity causes to the emitter excess diffusion, this wherein glass dust play crucial effects.Theory thinks that like this conductive silver slurry baked film is burning 400-600 ℃ at present, and glass has wherein begun softening and soaked into silver powder, and can dissolve part silver powder, and along with temperature further raises, the glass that contains silver begins to corrode SiN
X, to silicon substrate diffusion and reaction, in temperature-fall period, be dissolved in silver in the glass at first and can be inverted pyramid type crystal grain at silicon face and separate out, form directly with silicon and contact.There is one deck glassy layer (became uneven) between silicon substrate and the upper strata silver; Silver crystal grain directly contacts conducting with upper strata silver and exists hardly; Main conducting principle is the tunneling effect through thin layer of glass; That is to say that contact resistance depends on the silver-colored grain size separated out on the unit are silicon face under the silver layer and the thickness of quantity and intermediate glass layer, and PbO is considered to determine to corrode the key factor of SiNX and dissolving silver amount, therefore all positive silver pastes have all adopted flint glass at present.
From on July 1st, 2006, all were leaded, cadmium, and mercury, Cr VI gathers dibromodiphenyl ether and gathers bromo biphenyl, and the household electrical appliances of six kinds of harmful substances and other electronic electric equipments have been forbidden the market sale in European Union.For reducing harmful effect to environment; Electronic material also must be realized unleaded; The crystal silicon solar batteries front electrode is formed the conductive silver slurry of usefulness; To adopt crown glass exactly, therefore need the environment-friendly type crystal silicon solar batteries front electrode formation of a kind of function admirable of development to use conductive silver slurry.
Summary of the invention
