Definitions
- the invention relates to a method for the simultaneous microstructuring and passivation of silicon-containing solids by means of a liquid jet guided laser process.
- the laser beam localized heating of the solid surface, while in the liquid jet, a precursor for the passivation of the solid surface is included.
- the invention relates to a device for simultaneous microstructuring and passivation. The process is used in particular in the production of solar cells.
- a method for the simultaneous microstructuring and passivation of silicon-containing solids in which a liquid jet directed onto the solid surface and containing at least one precursor for the passivation of the solid surface is guided over the regions of the solid to be structured, wherein a laser beam enters the liquid jet is coupled, whereby the solid surface is locally heated by the laser beam and thereby at least partially structured and are saturated by the precursor formed by the structuring free surface bonds and so a passivation layer is formed on the structured areas of the solid surface.
- the inventive method is based on a liquid jet, in which a laser beam is coupled, wherein the laser beam in the liquid jet, which preferably has a diameter of ⁇ 100 microns, is guided. At the point of impact of the liquid jet on the solid surface, the laser beam likewise strikes and locally heats the solid. In this way, in this region of the solid surface, the temperatures necessary for the melting and e-vaporation of the solid can be generated.
- the carrier liquid in the liquid jet hits the molten one
- a crystal damage of the solid is avoided in the local microstructuring, as achieved by the use of short-pulse laser radiation, preferably with pulses ⁇ 15 ns, a rapid re-solidification of the surface melt and thus a movement of the melt is avoided by the liquid jet.
- the carrier liquid essentially contains the chemical elements hydrogen, oxygen, nitrogen or carbon
- their thermal decomposition on the hot solid surface can be used to saturate free surface bonds and to grow a passivation layer.
- the precursor is preferably selected from the group consisting of ammonium salts, in particular ammonium nitrite, ammonium nitrate, ammonium hydroxide or ammonium chloride, alkali metal salts of nitrous acid, N 2 O in an organic or aqueous solvent, especially in water, and mixtures hereof.
- ammonium salts in particular ammonium nitrite, ammonium nitrate, ammonium hydroxide or ammonium chloride, alkali metal salts of nitrous acid, N 2 O in an organic or aqueous solvent, especially in water, and mixtures hereof.
- the precursor is preferably selected from the group consisting of
- inorganic acids in particular nitric acid, hydrochloric acid or persulfuric acid, also in dilute form, organic acids, in particular peracetic acid, trichloroacetic acid or formic acid, BHF with oxidizing agent and mixtures thereof.
- the precursor is preferably selected from the group consisting of formic acid, glycol, glycerol, polyethylene glycol and mixtures thereof.
- the substrate is selected from the group consisting of silicon, glass, siliceous ceramics and their composite systems.
- liquid jet may preferably also comprise further additives, for example cleaning media, such as hydrochloric acid, for cleaning the structured areas.
- cleaning media such as hydrochloric acid
- a liquid jet that is as laminar as possible is used to carry out the method.
- the laser beam can then be guided in a particularly effective manner by total reflection in the liquid jet, so that the latter performs the function of a light guide.
- the coupling of the laser beam can e.g. by a window oriented perpendicular to a jet direction of the liquid jet in a nozzle unit.
- the window can also be designed as a lens for focusing the laser beam.
- a lens independent of the window can also be used for focusing or shaping the laser beam.
- the nozzle unit can be designed in a particularly simple embodiment of the invention so that the liquid is supplied from one side or from several sides in the jet direction radial direction.
- Preferred laser types are:
- solid-state lasers in particular the commercially frequently used Nd-YAG lasers of wavelength 1064 nm, 532 nm, 355 nm, 266 nm and 213 nm, diode lasers with wavelengths ⁇ 1000 nm, argon ion lasers of wavelength 514 to 458 nm and excimer lasers (wavelengths: 157 to 351 nm).
- the quality of the microstructuring tends to increase with decreasing wavelength because increasingly the energy induced by the laser in the surface layer is increasingly concentrated on the surface, which tends to reduce the heat-affected zone and thus to reduce it.
- the crystalline damage in the material, especially in the phosphorous-doped silicon below the passivation layer leads.
- blue lasers and lasers in the near UV range are particularly effective.
- the use of shortwave laser light in particular offers the option of a direct generation of electron / hole pairs in silicon, which can be used for the electrochemical process in nickel deposition (photochemical activation).
- free electrons generated in the silicon by laser light can directly contribute to the reduction of nickel on the surface.
- This electron / hole generation can be permanently maintained by permanent illumination of the sample with defined wavelengths (especially in the near UV with ⁇ 355 nm) during the structuring process and sustainably promote the metal nucleation process.
- the solar cell property can be exploited in order to separate the superconducting charge carriers via the p-n junction and thus negatively charge the n-conducting surface.
- the liquid jet has a
- sintering of the passivated regions of the solid state Surface is performed.
- sintering under forming gas is used in particular.
- the method according to the invention is suitable in particular for the structuring of silicon solar cells, and in particular for the edge isolation of solar cells.
- the surface can be locally melted or removed by a laser beam contained in the liquid jet acts on the surface.
- a suitable carrier liquid in the liquid jet a thin passivation layer can be produced on the surface. This passivation layer reduces the recombination activity on the one hand and an insulating one on the other hand
- the latter can e.g. be advantageous in the case of back contact cells or for subsequent metallization steps in the process chain.
- An apparatus for carrying out a method of the type described can be embodied such that it comprises a nozzle unit with a window for coupling a laser beam, a liquid feed and a nozzle opening, the nozzle unit being held by a guide device for controlled, preferably automated, guiding Nozzle unit over the surface layer to be structured.
- the device typically also includes a laser beam source with a light exit surface corresponding to the window, which may be provided, for example, by one end of a light guide.
- an apparatus for carrying out a method according to the invention can comprise a nozzle for generating the liquid jet and a laser light source. in which the nozzle and the laser light source are each held by a guide device or by a common guide device for guiding the nozzle and the laser light source over the same regions of the surface layer to be structured.
- Passivitations Mrs is used as a carrier liquid for the liquid jet, an aqueous solution with ammonium nitrite in a concentration of 3 mol / 1.
- the laser light source used is a 1064 nm Nd: YAG laser and a beam power of 76 watts.
- the travel speed of the substrate relative to the liquid jet is 100 mm / s.
- the beam diameter is 80 ⁇ m.
- a second embodiment of the front division of the emitter, followed by depositing a thin SiN x layer provides as a solvent for the nitrogen source perfluorodecalin.
- the nitrogen source used is nitrous oxide (N 2 O), which is dissolved in the liquid in a concentration of 0.1 mol / l.
- the laser light source is an Nd: YAG
- Laser of wavelength 1064 nm and the beam power of 76 watts The travel speed of the substrate relative to the liquid jet is 200 mm / s.
- the beam diameter is 80 ⁇ m.
- An exemplary embodiment for the front-side separation of the emitter with subsequent deposition of a thin SiO x layer provides as blasting medium a dilute aqueous solution of hydrochloric acid and hydrogen peroxide (H 2 O 2 ).
- the concentration of the hydrochloric acid is 0.01 mol / L, that of the hydrogen peroxide is 0.1 mol / L.
- the laser light source is a frequency doubled Nd: YAG laser with a wavelength of 532 nm and a beam power of 11 watts.
- the travel speed of the substrate relative to the liquid jet is 100 mm / s.
- the beam diameter is 60 ⁇ m.
