摘要:
The invention relates to a method for producing a doped silicon layer on a substrate, comprising the steps of (a) providing a liquid silane formulation and a substrate, (b) applying the liquid silane formulation to the substrate, (c) applying electromagnetic and/or thermal energy, wherein an at least partially polymorphic silicon layer is obtained, (d) providing a liquid preparation comprising at least one metal complex compound comprising aluminum, (e) applying said preparation to the silicon layer obtained in step (c), and subsequently (f) heating the coating obtained in step (e) by applying electromagnetic and/or thermal energy, wherein the preparation obtained in step (d) breaks down at least to metal and hydrogen, and subsequently (g) cooling the coating obtained according to step (f), wherein a silicon layer doped with Al or Al and metal is obtained, to doped silicon coatings that can be obtained according to the method, and to the use thereof for producing light-sensitive elements and electronic components.
摘要:
The present invention relates to a method for decreasing or increasing the band gap shift in the production of photovoltaic devices by means of coating a substrate with a formulation containing a silicon compound, e.g., in the production of a solar cell comprising a step in which a substrate is coated with a liquid-silane formulation, the invention being characterized in that the formulation also contains at least one germanium compound. The invention further relates to the method for producing such a photovoltaic device.
