Apparatus for measuring transmittance of cover glass for photovoltaic cell

摘要

An apparatus for measuring the transmittance of a piece of cover glass for a photovoltaic cell which can measure an accurate transmittance irrespective of whether or not the cover glass has a pattern and irrespective of the shape of the pattern. The apparatus includes a light source part disposed in front of the piece of cover glass. The light source part directs light into the piece of cover glass. A detector is disposed in the rear of the piece of cover glass, and detects light that has been directed into the piece of cover glass and then has passed through the piece of cover glass. The detector is disposed within a range where the intensity of the light that has passed through the piece of cover glass is uniform.
