Abstract

New Concentrated Optical Water Filter (COWF) for Photovoltaic (PV) applications is investigated. The COWF is placed in front of the PV module in order to reduce the thermal load on the PV. The COWF acts as a spectrum splitter to absorb the unwanted radiation and convert it to heat, and allow the useful radiation to reach the PV. The COWF consists of two parts; Optical Water Filter (OWF) and V-trough Solar Concentrator (VTSC). The OWF consists of two glass panels with specific gab filled with water which flows carrying away the heat and preventing it from reaching the PV. However, the disadvantage of using the OWF with PV is some reduction in the electrical power output of the PV due to optical losses. Therefore, VTSCs are developed to be integrated with OWF to overcome the optical losses. The VTSC consists of two reflectors placed as a (V) letter in front of the OWF in order to increase the solar radiation received by the PV to overcome the optical losses by the OWF. Overall, it can be concluded that COWF can enhance the electrical performance of the PV and reduce the PV temperature simultaneously relative to the PV module without COWF.
