ABSTRACT:
A metal layer (102) is formed on an insulating substrate (101), and a first transparent conductive layer (103) containing fluorine is formed on the metal layer (102). The metal layer (102) and the transparent conductive layer (103) are electrically divided by laser irradiation to prepare lower electrodes. A photoelectric conversion layer (105) is formed on the first transparent conductive layer (103), and a second transparent conductive layer (106) is formed on the photoelectric conversion layer (105). The transparent conductive layer (106) is electrically divided by laser irradiation to form upper electrodes. Then, lower and upper electrodes adjacent to each other are electrically connected by laser irradiation. According to this method of fabricating a photovoltaic element array, the resistivity of a connecting portion which electrically connects the lower and upper electrodes can be decreased. When the connecting portion is made narrow not to decrease a light-receiving area, an increase in resistance value of the connecting portion can be prevented.
