Concentrating Photovoltaics


For small to medium size solar thermal systems the special thermodynamic engines tend to suffer from high specific operating and maintenance efforts, or from too low efficiency. This creates a very attractive gap for the application of PV modules able to withstand concentrated solar beams and convert the sunlight directly into electricity at attractive efficiency levels. The concentrator quality becomes a critical issue, and the PV cells need to be special high-performance with appropriate cooling.
