Juan Francisco Martínez Sánchez Receives the Student Award for his Development of a New PV Hybrid Concentrator Module

At the 14th International CPV Conference in Puertollano, Spain, Juan Francisco Martínez Sánchez, doctoral student at Fraunhofer ISE, was distinguished with the Student Award for his talk »4-Terminal CPV Module Capable of Converting Global Normal Irradiance into Electricity.« Decisive is that his module not only uses the direct sunlight that is concentrated by lenses onto the miniature concentrator solar cells no bigger than several millimeters in size, but also the scattered light and diffuse radiation. This allows the module to achieve conversion efficiencies (with respect to global normal irradiance) that are unparalleled worldwide. Up to 36.8 percent module efficiency has already been measured on the roof of Fraunhofer ISE, and the development continues.
