Definitions
- the invention relates to a method and an arrangement for producing thin metal chalcogenide layers, for example for use as absorber or buffer layers in solar cells.
- CBD chemical bath deposition
- a substrate is immersed in succession in solutions of a metal salt and a readily soluble chalcogenide.
- the substrate is expediently rinsed after each bath.
- the metal ions adsorbed on the surface of the substrate in the first bath react with the chalcogenide ions in the second bath to form a poorly soluble metal chalcogenide.
- This treatment cycle is repeated until the desired layer thickness is reached (see M.P. Valkonen, T. Kanniainen, S. Lindros, M. Leskelä, E. Rauhala; Applied Surface Science, 115 (1997) pp. 386-392).
- the disadvantage of this method is the lack of uniformity (homogeneity) of the metal chalcogenide layer. In the case of substrates with porous surfaces in particular, a pronounced crust formation of the applied layer is evident.
- chalcogeno-urea is thermally decomposed in a bath of a dissolved metal salt or metal complex.
- Chalcogenide ions are released, which react with the metal ions adsorbed on the surface of the immersed substrate to form a poorly soluble metal chalcogenide (see TM Friedelmeier, D. Braunger, D. Hariskos, M. Kaiser, HM Wanka, HW Schock; Proceedings 25th PVSC, May 13-17, 1996, Washington DC, USA, pp. 845-848 ).
- the disadvantage here is that the process of metal chalcogenide formation occurs not only on the substrate surface but in the entire solution. It is therefore no longer usable after one run, although only a very small part of the solution has been used to coat the substrate.
- the process requires a very precise temperature control and the quality of the coating is very much dependent on the quality of the chalcogeno-urea used.
- different batches of chalcogeno-urea from the same manufacturer can lead to layers of very different quality. The causes of these quality fluctuations have not yet been clarified.
- the invention is therefore based on the object of specifying a method and an arrangement for the simple production of homogeneous metal chalcogenide layers of constant quality, taking economic and ecological aspects into account.
- Adsorption of metal ions 2. Removal of moisture from the substrate with the metal ions adsorbed on its surface, 3. Introduction of a gas containing chalcogen to react with the adsorbed metal ions.
- the solution of the metal compound can be applied to the substrate in an advantageous manner by spraying or by immersing the substrate in the solution.
- Ti0 2 , CulnS 2 , CuGaSe 2 , chalcopyrites in general or glass can be used as the substrate.
- a metal compound dissolved compounds of metals such as Cd, Cu, In, Pb, Ag, Sb or Bi are used individually or mixtures thereof, which form poorly soluble metal chalcogenides in reaction with hydrochloride.
- the metal compounds are usually dissolved in a volatile solvent such as methanol, ethanol, acetonitrile or mixtures thereof.
- a volatile solvent such as methanol, ethanol, acetonitrile or mixtures thereof.
- water can also be used as a solvent.
- water is particularly appropriate when a substrate with a defined residual moisture content is to be used for the chalcogenization of the adsorbed metal ions.
- the temperature regime for the process sequence is determined differently. The optimal one
- the process temperature can therefore also be above or below the usual room temperature.
- a subsequent drying in a gas stream from inert gases such as e.g. Noble gases or molecular nitrogen can be used.
- Dehumidification can also take place by evaporation of the solvent up to a defined residual moisture of the substrate.
- the evaporation can also take place during intermediate storage of the substrate covered with metal ions or during transport of the substrate.
- the reaction gas for the reaction with the adsorbed metal ions contains the hydrogen compounds of the chalcogens S, Se or Te.
- a rinse for the coated substrate in a solvent, preferably methanol, can expediently subsequently be carried out in order to remove excess reaction products and possibly. drying may be provided.
- the achievable layer thicknesses range from monomolecular to the ⁇ range. Depending on the desired layer thickness, the process cycle is repeated a corresponding number of times. Compared to the known methods described above, the method according to the invention has the advantages listed below:
- the metal salts used can be fully used instead of fewer percentages in the chalcogeno-urea process.
- the process according to the invention is therefore more economical and also more ecological (in particular in the case of toxic starting materials such as cadmium salts).
- the process sequence can be automated without great effort.
- the method according to the invention can in principle be used for all poorly soluble chalcogenides.
- the arrangement for carrying out the method according to the invention which has a movable substrate holder in all three levels, a bath of a dissolved metal compound, a drying vessel, a reaction vessel and a rinsing bath, is provided on the substrate holder with a cover which, after the substrate has been introduced into the reaction vessel Lowering the substrate holder ensures a gas-tight closure of the reaction vessel.
- the drawing shows a schematic representation of an arrangement for the automatic deposition of metal chalcogenide layers by the method according to the invention.
- An extremely porous Ti0 2 substrate is introduced into a metal salt bath of CdCl 2 dissolved in 90% methanol.
- the residence time is approx. 20 seconds.
- sufficient Cd ions have been adsorbed on the substrate surface.
- rapid drying max. 2 min
- H 2 S-containing gas stream The reaction time is approx. 10 - 20 sec.
- CdS is formed from the Cd ions adsorbed on the Ti0 2 surface.
- a rinsing in a methanol bath to remove excess reaction products.
- a final drying in an argon gas stream at high gas velocity is not absolutely necessary.
- individual layers of Cu x S and In 2 S 3 can also be applied sequentially to a substrate, which layers are converted into CulnS 2 by a subsequent annealing process.
- buffer layers made of CdS were applied to the absorber layer for CulnS 2 solar cells using the process parameters mentioned above.
- a substrate holder 2 with a substrate 3 which is movable in all three planes by means of a guide 1 is provided with a cover 4.
- CdCI 2 - solution bath 5 Cd ions are adsorbed on the substrate surface.
- the downstream drying vessel 6 is used for drying using argon.
- the CdS is formed by introducing H 2 S.
- the reaction vessel 7 is sealed gas-tight by the cover 4 attached to the substrate holder 2.
- the supply of H 2 S gas only begins when the reaction vessel 7 is closed gas-tight and the suction pump is switched on.
- the rinsing bath 8 follows. Here, the excess reaction products are washed out using methanol.
