Paper Abstract

High-concentration PV systems offer a viable alternative to conventional modules mainly because of the high energy density produced for unit surface of photovoltaic cells. Optimal performances can be obtained by employing simultaneously receivers sensitive to different wavelengths by a proper partitioning of the concentrated solar spectrum. At the same time secondary concentrators with the ability to homogenize the illumination field must be employed to maximize cells performances. The use of a dichroic mirror and compound parabolic concentrator (CPC) homogenizers allows to forecast overall system performances capable of justifying the development of systems for residential applications. Moreover the concentrating systems may open prospects for large scale energy applications.
