Description
Technical field
The invention belongs to technical field of solar batteries, and in particular to a kind of graphite boat saturation process of solar cell.
Background technology
At present, polysilicon solar cell technique has reached its maturity, and realizes standardized production, main technological steps are such as
Under:Acid corrosion making herbs into wool → diffusion → wet etching → PECVD coated with antireflection film → silk-screen printing → sintering → testing, sorting.
Wherein, PECVD coating process plays a decisive role to the color appearance of solar battery sheet, and the saturation quality of graphite boat is direct
Influence the uniformity of plated film color.Graphite boat saturation mode is a traditional saturation process in industry, after this technique saturation
Graphite boat service life is shorter, first five boat color distortion is larger after new boat saturation after cleaning, and mainly color distortion is deposited greatly in piece
In the thin bad order in the red center of silicon chip edge, bad order ratio is up to more than 80%.Graphite boat using the present invention is satisfied
And method, new boat plated film color uniformity consistency can be made good, color distortion in piece caused by greatly reducing new boat uses this
Method can reduce plating boat cost, and the component used in saturation graphite boat may be reused for ceramic jacket in graphite boat component.
The content of the invention
It is an object of the invention to provide a kind of graphite boat saturation process of solar cell, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides following technical solution:The graphite boat saturation process of solar cell, including
Remove silicon nitride layer, rinsing, drying, assembling, saturation, again dismounting, saturation and plated film.
In addition, the graphite boat saturation process of solar cell of the present invention comprises the following steps:
S1, removal silicon nitride layer:Silicon nitride layer is plated using 5%-20% hydrofluoric acid solutions removal graphite boat piece;
S2, rinsing:Graphite boat piece is rinsed using pure water, rinsing 4 times every time 2 it is small when;
S3, drying:Graphite boat piece is dried with baking oven, drying temperature 80-120 degree;
S4, assembling:Graphite boat and installation card point protection component are assembled, ceramic card point protection component internal diameter is entangled graphite boat card
Point, protects all graphite stuck points according to the method, and porcelain bushing is used for that graphite stuck point border is avoided to be coated with silicon nitride film;
S5, saturation:Saturation graphite boat carries out graphite boat using PECVD plating boat saturation, and saturated gas used is ammonia and silicon
Alkane;
S6, dismounting:It removes stuck point protection component and completes boat integral installation with checking;
S7, again saturation:Satisfy again and saturation mainly is carried out to graphite clamping point, saturated gas used is ammonia and silane;
S8, plated film:It is normally carried out coating process.
The technique effect and advantage of the present invention:The graphite boat saturation process of the solar cell, passes through installation card point protection
So as to reach protection graphite boat card, stuck point protection component for ceramic jacket can recycle, first graphite boat piece is grown component
Time silicon nitride layer saturation, then by stuck point protection component removed after secondary plating boat saturation, use two kinds of saturation mode knots
Conjunction has fully carried out saturation to graphite boat piece, in turn avoids in long-time saturation history stuck point partial silicon nitride plated film to battery
The influence of piece color generates the more uniform monolithic no color differnece of silicon chip film-coated color, and plated film colour consistency improves, and plated film is done over again
Ratio reduces, and can substantially reduce saturation graphite boat cost, and new boat plated film color is uniform after saturation, colour consistency between piece inner sheet
Good, the finished battery factor of merit is promoted.
