| Description: |
Concentrator photovoltaic (CPV) technology, because of the extremely high efficiencies achieved by CPV systems, is nowadays widespread all over the world. Recently, the strong development in the methods and processes used to manufacture both solar cells and optical systems for CPV opened the door to the new frontier of the micro-CPV, that are systems that employs solar cell with a surface aperture smaller than 1 mm2 [1]. The reduction in size of the solar cell implies the proportional shrinking of all the other components, which in turn made possible the implementation of novel features such as the integrated tracking. This technology has been conceived to avoid the use of the external tracking system. Hence, the primary optical element (POE) is designed in order to maintain the shape of the light spot also when sunlight impinges the lens with high incident angles (i.e. ±60º). Obviously, the spot position with respect to the lens varies requiring that the solar cells inside the module follow the spot (see figure 1a). Nowadays, several possible architectures for integrated tracking are being investigated around the world. However, the closest to industrialization is the concept developed by the Swiss company Insolight SA which is currently being developed within the framework of the European project HIPERION (https://hiperion-project.eu/) [2]. Along the project, the modules continuously evolved from the first generation (called GEN0 and developed before the beginning of the project) to the current configuration (GEN2) implementing a series of overall improvement based on the experience learned along the technology development. This work is mainly focused on the difference between GEN1 and GEN2, where the optical design drastically changed. |
