<p><P>PROBLEM TO BE SOLVED: To provide a conductive composition for a solar cell electrode which can manufacture the solar cell having both the high electrical performance and the bonding strength of the electrode. <P>SOLUTION: Conductive paste comprises glass containing 0.1-7.0 (mol%) of a copper oxide, and in applying the conductive paste to a substrate to execute heat treatment to form a light-receiving face electrode, the excessive diffusion of silver can be suppressed. Thus, parallel resistance is reduced due to the excessive diffusion of silver and a curve factor becomes small, and a pn-junction is prevented from being damaged in an extreme case. Furthermore, since the copper oxide is contained in a range of the described mol%, a softening point of the glass is reduced, and the bonding strength of the light-receiving face electrode to be formed is improved. Accordingly, the conductive paste capable of manufacturing the solar cell having both the high electrical performance and the bonding strength of the light-receiving face electrode is obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
