Abstract

The present invention provides an inspecting apparatus for photovoltaic devices, which is able to identify a zonal defect position in a photovoltaic cell. The inspecting apparatus for photovoltaic devices of the present invention includes an identifying means of the position of the zonal defect with applying a suitable search window (43) to an image representing a photovoltaic cell in an electrified state. The search window (43) includes a first area (40a) and a second area (40b) separated into two parts by the first area (40a). The identifying means of the zonal defect position identifies the zonal defect extending toward the same direction with the first area based on the brightness within the first area (40a) and the second area (40b) while the search window (43) is applied to the photovoltaic cell.
