<p><P>PROBLEM TO BE SOLVED: To provide a method of inexpensively manufacturing a solar cell with higher photoelectric conversion efficiency capable of raising the dopant concentration only for a portion in contact with an electrode without using many processes as in photolithography when an application agent is coated and a dopant is diffused at a high temperature. <P>SOLUTION: The manufacturing method of the solar cell is adapted such that in the solar cell including a pn junction formed with the aid of an application/ diffusion method using a single crystal silicon substrate or a polycrystalline silicon substrate as a substrate, there are used as the application agent ones containing a plurality of kinds of the dopants or ones having a plurality of dopant containing concentrations, and the application agents are independently applied on the substrate by making use of an ink jet method taking the application agent as ink. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
