Nowadays, the photovoltaic conversion is a consolidated technology and can be efficiently combined with solar concentration. In this study, a new concept of photovoltaic solar concentrator based on nonconventional mirrors coupled with high efficiency triple-junctions cells is described and discussed. More in details, as for the optical design, deformations are applied to classical spherical mirrors to control solar aberrations and boost efficiency of a receiver consisting in a dense array of cells. The efficiency enhance is obtained by high matching between the collected solar irradiance and the receiver electrical features. The concentrator is able to produce both electrical and thermal energy: the system requires in fact an active cooling circuit to maintain the cells performance. This behavior makes the system suitable for combined heat and power applications with particular reference to high direct irradiance environments. An analytical study, considering a residential utility has been performed in order to understand the energetic and economic performance of the system. In particular, a simulation has been carried out by the use of an in-house-developed calculation code considering a whole year of operation.||Conference Name:||Clean, Efficient and Affordable Energy for a Sustainable Future: The 7th International Conference on Applied Energy (ICAE2015)||Conference Place:||Abu Dhabi, United Arab Emirates||Conference Date:||March 28-31, 2015||URI:||http://hdl.handle.net/20.500.12386/23433||URL:||https://www.sciencedirect.com/science/article/pii/S1876610215011595?via%3Dihub||ISSN:||1876-6102||ISBN:||9781510812246||DOI:||10.1016/j.egypro.2015.07.391||Fulltext:||open|
