导电性组成物及其制造方法、太阳电池;CONDUCTIVE COMPOSITION AND METHOD FOR MANUFACTURING THE SAME, SOLAR CELL

摘要

本发明的课题在于提供一种于形成太阳电池的电极时可实现良好的电接合的导电性组成物的制造方法。本发明是用以形成太阳电池的电极的导电性组成物的制造方法，其包括：准备银粉末、含碲组成物、及碲价数调整材料；以将该导电性组成物涂布于太阳电池的基板并进行了煅烧时的该基板与导电性组成物的界面所含的碲(Te)的平均价数成为4.3以上且5.1以下的方式，调整银粉末、含碲组成物及碲价数调整材料的配方而制备导电性组成物。; and adjusting a mixture of the silver powders, the tellurium-containing composition and the tellurium valence adjusting material in a manner that an average valence of tellurium containing in an interface of a substrate and the conductive composition when the conductive composition is coated on the substrate of the solar cell, and calcined is 4.3 to 5.1 so as to prepare the conductive composition.
