This paper presents the new module generation (CX-75-III), which was developed in an all-embracing cost optimization. The single primary lens was refined for optical efficiency and its size increased to 5.7×5.7cm 2, thus dramatically reducing the part count. Thermal simulations were used in order to dimension the heat spreader and ensure the reliability due to a low cell temperature. Furthermore, recent developments for cost optimization and high module efficiencies are presented. Results on prototype modules with a new heat spreader design, a new primary lens and also with refractive secondary optical elements are shown. The use of reflective secondaries has lead to an STC efficiency of 30.6%. Furthermore, different anti-reflection coatings have been examined in order to assess their impact on performance and reliability
