Abstract
A transparent conductive film is formed on a glass substrate covering substantially its entire surface area and this transparent conductive film is divided into a plurality of transparent conductive parts per each photoelectric converting region. The photoelectric converting region is of a nearly rectangular shape, and accordingly, in order to divide the transparent conductive film into respective transparent conductive film parts, a laser beam is irradiated along all longitudinal and lateral sides of the rectangle. Thereby, the transparent conductive film parts corresponding to the photoelectric converting regions are formed as island regions. Semiconductor film parts are formed on the transparent conductive film parts divided into island regions corresponding to respective photoelectric converting regions and subsequently aluminum film parts are formed on these semiconductor film parts. Transparent conductive film parts are electrically connected to aluminum film parts of adjacent photoelectric converting regions. Thus, a photovoltaic device is manufactured wherein a plurality of photoelectric converting regions are formed on the substrate and respective photoelectric converting regions are connected in a series fashion.
