Seven configurations of Photovoltaic (PV) energy conversion systems were investigated and their performances compared to direct solar PV conversion. The systems involved use of filters, concentrator lens, fiber transport, and direct use of PV. Transmission of concentrated light onto PV cell proved to be the most efficient, but also the most expensive. However, transmission of filtered light onto PV cell using a plastic optical fiber (POF) bundle was the most affordable. The current price of fiber optic for light transport, though interesting, renders them economically not viable for energy conversion. (C) 2011 Elsevier Ltd. All rights reserved.
