太陽電池の製造方法
Document Type and Number:
Japanese Patent JP4650842
Kind Code:
B2
Abstract:
To provide a method of manufacturing a solar battery of excellent characteristics in a simple process by using a phosphor based dopant coating liquid in a form suitable for application by an inkjet method.
The method of manufacturing the solar battery includes: a step of applying the alcoholic solution of phosphorous acid to a p-type semiconductor substrate by the inkjet method so that the dots of the alcoholic solution of the phosphorous acid partially overlap; and a step of forming the n-type diffusion layer of a different phosphor concentration on the p-type semiconductor substrate by thermally diffusing phosphor.
