Concentrator photovoltaic (CPV) modules are composed of many components and interfaces, which require complex assembling processes, resulting in fabrication complexity and often lack of reliability. The present work addresses these issues, by proposing an innovative low concentration photovoltaic (LCPV) concept. In particular, the purpose here is to develop a module with a high level of integration by lowering the number of components and interfaces. The mirror used as the concentrator optic is multifunctional, as it combines thermal, structural and optical function. Moreover, the proposed design claims to demonstrate the applicability of reliable flat PV processes (such as lamination and cells interconnections), for the manufacturing of this LCPV module. The paper describes both indoor and outdoor characterization of a new prototype. Performances by means of IV curves tracing will be discussed regarding the losses distribution within the optical chain. © 2017 Author(s).
