Title: Performance of a Prototype Stationary Catadioptric Concentrating Photovoltaic Module

A stationary catadioptric concentrating photovoltaic module with aperture area over 100 cm2, geometric concentration of 180x, and collection within 60° of polar incidence was designed, prototyped, and characterized. The module performance followed modeling closely with a peak power conversion efficiency of 26% for direct irradiance. Tracking of the sun is accomplished via translational micro-tracking completely internal to the module, avoiding the cost and complexity of mechanical two-axis trackers that point towards the sun. This study demonstrates the potential for concentrating photovoltaic modules with significantly higher efficiency than industry standard silicon photovoltaic modules that could be installed in stationary configurations on rooftops.
