Abstract
This invention relates to a method of manufacturing a thin-film solar battery comprising a plurality of photo-electric power generating elements connected in series. It comprises a process of arranging two or more photoelectric power generating elements each including a junction electrode, back electrode, semiconductive layer, light-permeable electrode, (and current collecting electrode) laminated in this order on an insulative and light-permeable substrate and a process of irradiating a laser beam from the substrate side to the junction electrode of one of adjacent photoelectric power generating elements to melt the junction electrode and to connect the back electrode of one of the adjacent photo-electric power generating elements and the light-permeable electrode (or current collecting electrode) of the other of the adjacent photoelectric power generating elements with the coagulation of the melt. Accordingly, since the back electrode can be patterned prior to the formation of the semiconductive layer and since the series connection of adjacent photoelectric generating elements can be made by laser bonding from the substrate side, the photovoltaic characteristics of the semiconductive layer are never impaired.
