Adding a dielectric Secondary Optical Element (SOE) to a Concentrating Photovoltaic (CPV) system provides several advantages. Besides increasing the concentration-acceptance angle product attainable by the system, a more uniform irradiance on the solar cell can also be achieved. The most common solution to glue the SOE and the solar cell consists in using an elastomer such as silicone. In this case, the silicone is acting both as an optical coupler to reduce Fresnel losses and as a mechanical bond. In this paper, we present a new approach to fix the thickness of the silicone in order to ensure a good adherence.
