SOLAR BATTERY CELL AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a solar battery cell together with its manufacturing method, wherein a relatively minute electrode is easily formed on a solar light receiving surface in a simple process. SOLUTION: Each of a plurality of comb-like electrodes 30 provided on a solar light receiving surface 28 comprises an electroless plating conductive layer 39 which is directly fitted to the solar light receiving surface 28 of a semiconductor body in an electroless plating process P7. So, the electroless plating conductive layer 39 is selectively formed only by touching electroless plating liquid. Compared to a conventional process in which a metal vapor- deposition layer is formed before forming a plating conductive layer 40, the expensive manufacturing facility for metal vapor deposition in a vacuum chamber and a relatively large space therefor are not required, resulting in a relatively simple process, while the decrease in the number of processes lowers a manufacturing cost. The mask alignment for forming an electrode is not required. Such a inconvenience as increase in the number of process or decrease in yield caused by variation in the alignment is settled.
